Belvoir Park Hospital, Hospital Road, Belfast, BT8 8JP

Belvoir Park Hospital is an extensive Edwardian hospital complex designed in English Renaissance Revival style by the Belfast architectural firm Young and Mackenzie. It was designed in 1900–01 and built between 1904 and 1906, with the contractor Robert Corry Ltd of Belfast, decorative stone carving by Winter and Thompson of Belfast, and an electric turret clock made by Sharman D. Neill of Belfast. The complex was built as the Infectious Diseases Hospital by Belfast City Corporation — the city's first municipal hospital — on a portion of the Purdysburn Estate that had been re-allocated under the City of Belfast Hospitals Act, which became law on 1st July 1903. Young and Mackenzie were appointed on 10 May 1900, following which John Mackenzie visited the principal fever hospitals in England and Scotland to study the most up-to-date approach to such buildings. The plans were approved in August 1901, and the complex was officially opened on 2 August 1906 by the Lord Lieutenant, Lord Aberdeen, Viceroy of Ireland, who planted an oak tree to mark the occasion. What was originally Pavilion A (now Pavilion 1) was named the Ishbel Aberdeen Pavilion in honour of the Viceroy's wife, at the request of the Public Health Committee of the city council.

The complex is laid out according to the pavilion system of hospital planning — a rational arrangement of separate ward blocks designed to minimise cross-infection — of which there are few surviving examples in Northern Ireland. The buildings are constructed in red brick with sandstone dressings and are generally plain in character, with English Renaissance detailing concentrated on the principal public-facing elevations. The six main ward pavilions are aligned north–south in pairs, with their main entrances facing east or west, connected by a covered open-air corridor system extending from the main administrative block. The main entrance gateway faces east and forms a group with two flanking lodges.

Not all of the intended complex was complete by the time of the 1906 opening. At that stage the complex comprised the main entrance gateway and lodges, the administrative block, four ward pavilions (the two on the east side for diphtheria and enteric diseases, the two on the west side for scarlet fever, with the southernmost pavilion on each side originally completed as a single-storey building), an observation pavilion to the extreme south, and a disinfecting house, laundry, engine and boiler house, stables, and mortuary to the west. The lodges originally functioned as a residential lodge on one side and a shelter for the admittance of authorised persons and patients on the other. The administrative block originally housed offices, consultation rooms, residential accommodation for the matron, assistant medical officers, and servants, a nurses' home, dining room, and kitchens. Ward floors were originally of tongued and grooved teak laid on concrete.

Later additions, all designed by Young and Mackenzie, included the covered open corridor system (date unknown), two-storey wings to the administrative block (date unknown), new pavilions in 1911 and 1914, and a new Nurses' Home in 1926, designed by James R. Young of Young and Mackenzie. The hospital was previously known as Purdysburn Fever Hospital, later as the Northern Ireland Fever Hospital and Radiotherapy Centre, before becoming Belvoir Park Hospital. Within the grounds stands a monument (SMR Down 9:32).

MAIN ENTRANCE GATEWAY

The main entrance gateway comprises a pair of original square-section red brick piers with large gabled sandstone caps surmounted by modern lamp fittings; the original gates have been removed. Extending to the north of the right-hand main pier is a low screen wall, cement rendered with chamfered sandstone coping, surmounted by original wrought iron railings, which curve forward to terminate in a square red brick end pier matching the main piers but without a lamp. The railings and pedestrian gate have curved finials, and both runs of railings carry the name of the hospital in later painted steel letters. Extending to the south of the left-hand main pier is an original wrought iron pedestrian gate connected to a matching pier without a lamp standard, beyond which a screen wall with terminal pier matches those to the north. The southern screen railings include a large curvilinear wrought iron stay connected to the screen wall. The two central main piers have modern steel security gates mounted on their rear faces. The rear face of the southern main pier also carries a run of original railings connecting to the open porch of the South Gate Lodge.

SOUTH GATE LODGE

The South Gate Lodge is a single-storey building comprising a main rectangular gabled block with a later lower gabled rear return, a later flat-roofed rear extension, and a lean-to open porch to the front. The main entrance faces north onto the main driveway, while the main gable faces east to the public road.

The entrance front has a roof of Bangor blue slates in regular courses with terracotta ridge tiles of serrated profile, a central chimney of red brick with a sandstone cap and two pots, and walls of red brick. Two rectangular timber panelled doorways are provided, the left-hand one containing a small later rectangular spy hole; both have plain timber architraves in plain reveals, chamfered sandstone lintels, and modern metal handles and locks. A concrete step serves the left-hand door. A lean-to open porch projects at the left-hand portion, with a swept roof supported on two circular corner cast iron posts, a decorative tongued and grooved frieze, and a decorative tongued and grooved cheek to the west side (the east side cheek is now missing).

The main gable has a curved coping of shaped sandstone with a shallow central curved bay containing three windows — modern PVC fixed lights with top-hung vents in plain reveals — set on a continuous curved sandstone cill beneath a chamfered continuous lintel, surmounted by a small ogee lead roof with a concealed gutter. The apex of the gable contains a carved sandstone shield depicting the arms of Belfast.

The rear elevation matches the entrance front in roof and walling materials, with one window to the right-hand side. To the left is a later lower gabled rear return of red brick with one rectangular two-panel timber doorway in the east side (without handle, with a plain concrete lintel) and a window with a flat brick arch lintel and sandstone cill. The south gable is blank. The flat-roofed extension has a rectangular timber louvred doorway in its south side and a small window in its west side, with a modern zinc-painted flat roof covering turned down over the fascia. The west gable of the main block has a large central modern rectangular PVC window with a projecting sandstone cill and chamfered sandstone lintel, and a smaller PVC window to its right in plain reveals with a concrete cill. A small concrete path runs around the lodge with a grassy bank to the rear.

NORTH GATE LODGE

The North Gate Lodge is a one- and two-storey building of asymmetrical plan, comprising a main rectangular two-storey block with a diagonal bay to the south-east corner and a single-storey block to the west. The main entrance faces south onto the main driveway.

Roofs are of Bangor blue slates in regular courses with terracotta ridge tiles. Two chimneys are present: one on the two-storey block of red brick with a sandstone cap (pots obscured by creeper) and one entirely covered by ivy. Walls are of red brick with a projecting brick plinth, projecting brick quoins to the extremities, a moulded sandstone stringcourse at first-floor level of the two-storey block, and moulded sandstone cornices. Rainwater goods are moulded cast iron gutters with circular cast iron downpipes.

The main entrance is a rectangular timber glazed and panelled door surmounted by a plain fanlight, set in a plain timber surround with projecting long-and-short brick surrounds; two moulded sandstone steps; and a slightly projecting rusticated sandstone flat arch to the head. One window at ground-floor level in each block: rectangular timber sliding sash, vertically hung, 1 over 1, with horns; projecting sandstone cills; rusticated brick surrounds with apron; slightly projecting rusticated sandstone heads of flat-arch type, the one to the left comprising long-and-short voussoirs and the one to the right cut from a single stone. The two-storey diagonal bay at the right-hand end contains one window to each floor; a curvilinear gable coping in sandstone with shaped kneelers and a ball finial to the apex; windows are sashed as elsewhere, with cills and aprons as elsewhere, in plain reveals to the sides; flat-arch head to the ground floor as elsewhere, with five voussoirs; three voussoirs to the first floor. The diagonal bay has blank sides except for cast iron downpipes on the right-hand side.

The west elevation has a brick gable with what appears to be a cement rendered barge, a shallow projecting bay to the right-hand side, and a window to the left of it: the window in the gable is rectangular sashed with rusticated surrounds, and the bay contains a similar window in plain reveals with a hipped roof of Bangor blue slates. To the right of the projecting bay is a ventilator brick with ornamental perforations. The rear elevation is completely covered in creeper with thick foliage at the base, making detailed recording impracticable. The east elevation has a brick gable with barge as on the west; one window to each floor, rectangular sashed, with rusticated surrounds and flat-arch heads — three voussoirs to the first floor rather than five. A narrow concrete path runs across the front and sides of the lodge; a tarmac path leads to the entrance, flanked by small lawns, with a thick laurel hedge abutting each side and to the rear.

ADMINISTRATIVE BLOCK

The administrative block is a two- and three-storey building of red brick with sandstone dressings in English Renaissance style, with a long rear return. The main entrance faces east.

The entrance elevation is symmetrical and comprises a central three-storey gabled eleven-bay block with later flanking two-storey end wings. The central block has a roof of Bangor blue slates with dark-toned ridge tiles, surmounted by a central octagonal lantern with a battered lead-covered base, an arcaded and louvred main stage with moulded cornice, and an ogee copper dome with weather vane. Two chimneys on the front ridge are of red brick with sandstone caps and red pots. The walls are of red brick with a projecting brick plinth, projecting moulded sandstone stringcourses at first-floor and eaves levels, rising to a brick parapet with ramped sandstone copings. A concealed gutter runs behind the parapet, with circular cast iron downpipes.

The central projecting entrance bay is of channel-rusticated sandstone to the ground and first floors, rising to rusticated quoins at second-floor level, which carry a broken curvilinear pediment with modillion cornice, all surmounted by a dressed stone rusticated chimney. The main entrance is a segmental arch containing a rectangular timber panelled door with panelled timber sidelights and a plain fanlight; six steps lead up to the doorway, their risers and treads finished with later modern tiles. The rusticated sandstone arch has moulded recessed panels, and an egg-and-dart moulding to the sandstone cornice, surmounted by a semi-circular tympanum containing the Belfast city arms in carved sandstone. Above the tympanum at first-floor level is a rectangular timber sliding sash window, 1 over 1 vertically hung with horns, set in a moulded sandstone heeled surround with a projecting keystone. Above at second-floor level is a similarly sashed window in a moulded rectangular sandstone surround with a richly ornamented keystone, surmounted by a clock face set in a carved sandstone laurel wreath surround. The rusticated chimney at the top contains a recessed semi-circular panel inscribed 1904 in raised sandstone numerals; six pots to the top of the stack.

The walls flanking the entrance bay are each two windows wide. Windows are sashed as described, except for basement windows in the plinth which are two-pane central-pivoting timber lights. All windows are set in plain reveals. Basement windows have projecting sandstone cills and flat-arched brick heads. Ground-floor windows have similar cills and rusticated sandstone flat-arch heads of five voussoirs. First-floor windows have a stringcourse cill and a flat sandstone arch of three voussoirs. Second-floor windows have projecting sandstone cills with brick aprons and similar heads to those at first-floor level.

Projecting to each side of the main front wall are three-storey canted bays, three windows wide with one window in each face; windows are detailed as elsewhere for each floor level, except that the ground- and first-floor windows of the right-hand canted bay have been replaced with modern rectangular timber fixed lights, or fixed lights with opening lights, 1 over 1. The flanking end wings are of two storeys with hipped slated roofs, walling as the central block, a central projecting chimney breast with sandstone kneelers; inner bays contain one window to each floor detailed as elsewhere; outer bays are blank. The left-hand wing has a single chimney pot projecting above parapet height.

The south elevation has a large shaped curvilinear gable to the right — with a moulded sandstone coping with scrolling ends and a ball finial to the apex, and a plain sandstone shield with Tudor drip moulding in its centre — and a three-storey canted bay to the left with a ramped parapet and hipped roof behind. Walling, roofing, and window detailing are as elsewhere. The two-storey wing referred to on the entrance front projects from the curved gable as a canted bay with two windows wide to the front face, sashed windows as elsewhere to each floor, in each face. This two-storey canted bay extends to the left as a two-storey rectangular bay with one window in each floor, sashed as elsewhere except at ground floor where it has been replaced by a PVC fixed light with a top-hung bottom light. To the left of the rectangular bay is a single-storey canted bay two windows wide to the front face, with all windows replaced by PVC as described; the parapet coping is of concrete, with a concealed gutter and a cast iron downpipe. To the left of that is a single-storey red brick block with a semi-circular arched opening from which projects a covered open corridor; modern PVC piping projects from the parapet. This block extends further left as another single-storey canted bay, four windows wide to the front face and one window to the sides, with all windows replaced by PVC, and concrete cills and parapet coping; the rusticated flat-arch window heads are of concrete. The west side of this block is four windows wide, all PVC as described, with concrete cills and plain concrete lintels.

The rear elevation is three storeys with a hipped slated roof; three chimneys on the ridge of red brick with sandstone haunching; three pots to the southern chimney and four to the northern. Two windows to the first floor and two to the second floor to the right of the rear return are sashed as elsewhere with similar heads. Walling is plain red brick without strings, terminating at the right-hand extremity in a projecting plain red brick chimneystack with sandstone cap and one pot. A plain parapet has a projecting sandstone coping. The rear elevation to the left of the rear return is seven chimneys wide, with sashed windows as elsewhere with keyed flat-arched heads, except for two windows which are coupled about a central mullion. The second opening from the left is a doorway containing a rectangular flush timber door with a plain fanlight, opening onto a fire escape stairway. Windows to the first floor are sashed as elsewhere.

The north elevation has a large shaped curvilinear gable to the left, matching that on the south elevation, with a two-storey canted bay projecting from it forming the two-storey wing visible on the entrance elevation, with a shallow projecting rectangular entrance bay set back to the right of it, extending to the right into a projecting three-storey canted bay. Canted bays have ramped parapets with hipped slated roofs behind. Walling and windows are as on the entrance front, except that the front face of the ground floor of the two-storey bay contains a large single timber fixed light window in place of two original windows, with cills connected by a sandstone block and rusticated heads rearranged to form a single head carried on a metal plate. The entrance bay contains a doorway at ground-floor level: a pair of rectangular timber glazed and panelled doors with modern metal push plate, set in a sandstone surround comprising plain Doric pilasters carrying a rusticated semi-circular arch containing a plain semi-circular sandstone tympanum, rising to form the apron of the window above. Four concrete steps are contained by red brick dwarf walls with chamfered sandstone copings and a modern tubular metal handrail. The first-floor window is a tall rectangular timber sash, vertically hung, 2 over 2 with horns, surmounted by a plain semi-circular headed fanlight, set in a rusticated sandstone arched surround. The second-floor window is rectangular sashed as elsewhere. A cast iron downpipe is on the right-hand side of the entrance bay.

At the right-hand end, set back, is a doorway containing a pair of double doors as elsewhere on this elevation, surmounted by a plain rectangular fanlight in plain brick reveals, with a segmental arched head below a parapet of single-storey height with concrete coping; six concrete steps lead up to it. This links with a later block of two storeys with a complete basement at lower ground level, reached by a flight of ten lateral steps. The modern block is of plain red brick with a chamfered projecting plinth. Its windows are rectangular timber sashes, 1 over 1 with horns, set in plain reveals with concrete cills and artificial stone lintels, with a concrete parapet, cast iron and PVC pipes, and a narrow timber panelled door in the basement. The south side of the modern block has two windows sashed as described to its west side.

The rear return comprises a U-shaped arrangement of four-storey blocks connected to the main building by a link block. The south elevation of the link has a slated roof with two storeys of white painted timber panelling containing large fixed light and top-hung windows. The south elevation of the main return block has a hipped slated roof, plain red brick walling with a projecting brick eaves course and a projecting plinth to the partly sunken basement storey set within a light well. Rainwater goods are moulded cast iron gutters with circular cast iron downpipes. Basement windows are segmental-headed timber sliding sashes, 1 over 1 with horns, with projecting cills and segmental brick arched heads. Upper-storey windows are mainly rectangular sashes with brick flat-arch heads, except for three rectangular PVC fixed lights with top-hung opening lights set in segmental arches at ground-floor level. Two doorways are provided: one at ground-floor level opening onto a concrete bridge, one at first-floor level opening onto an iron fire stair.

The west elevation has window heads as described for the south elevation, with sashed windows as elsewhere. Four rectangular flush timber doors — two with modern fanlights or sidelights — open onto metal escape stairs or ladders. A later elevated link block between the wings of the return has modern metal side-hung casement windows with large modern concrete lintels. Below is a pair of large diagonally-braced ledged timber doors; beyond is an open light well with elevations of similarly plain character to the exterior faces. The north elevation of the link has plain red brick walling containing two windows at first-storey level, rectangular timber sashed as elsewhere. The north elevation of the main return block is similar to the south, except that all windows are either original sashed or later metal-framed; the basement storey is fully exposed; and there are no escape stairways.

COVERED WAY

The covered way is an extensive open-sided corridor running longitudinally from north to south, from the administrative block to Montgomery House (the former observation pavilion), with three transverse corridors leading to the six free-standing ward pavilions — three to each side, east and west. It was constructed on the layout of the original underground electrical cable routes between buildings.

The corridor system comprises a screed floor contained by small kerbs, flanked by concrete gutters, with manhole covers giving access to the underground ducts. Paired iron girder posts at regular intervals, with curved flanges, support iron beams to each side, which carry light iron trusses braced at intervals, with a pitched roof of translucent glazed panels. The sides are filled to half height by fretted wooden railings with a moulded handrail. Rainwater goods are moulded cast iron gutters with circular cast iron downpipes. The pavement expands to an octagonal plan at the junctions of the longitudinal corridor with the transverse corridors.

At the north end the corridor abuts the administrative block, on axis with the transverse service corridor of that block. At the south end the original longitudinal corridor cants slightly to the west, where its originally open sides have been filled in with modern glazing; at its extremity it is abutted by a later modern corridor with a tongued-and-grooved timber-sheeted dado on a concrete plinth, surmounted by translucent glazed panels in timber frames with similar roofing on simple collar beams, PVC gutters, and downpipes. This modern continuation terminates in a modern lean-to passageway at the Northern Ireland Radiotherapy Centre.

The transverse corridors are of similar form to the longitudinal corridor, except that the one leading to Pavilion 5 has its originally open sides filled in with modern glazing. Each transverse corridor ends at a porch of higher ridge height, as described at each ward pavilion entrance front. At the north end on the east side there is an open pedestrian gateway leading onto a path branching from the main driveway, marked by a pair of shaped cast iron posts with ball finials.

PAVILION 1

Pavilion 1 is a two-storey building of red brick with sandstone dressings, with a symmetrical frontage comprising a central gabled three-bay entrance block projecting in front of a long rectangular block that extends to each side as two six-bay wings, each joined by short single-bay links to single-bay hipped end blocks. The main entrance faces west. This pavilion was named the Ishbel Aberdeen Pavilion in honour of the wife of the Lord Lieutenant who opened the hospital in 1906.

Roofs are of Bangor blue slates in regular courses with red ridge tiles. Three chimneys on the ridge of the main block are of red brick with sandstone caps; pots are present only on the central stack. Walls are of red brick with projecting brick eaves courses, a projecting brick plinth containing a basement, and a moulded sandstone stringcourse at first-floor level; the central entrance block has further dressed sandstone detailing. Rainwater goods are moulded cast iron gutters with original cast iron downpipes. Windows are original rectangular timber sliding sashes, 1 over 1 with horns, surmounted by a bottom-hung top vent, except where modernised, set in raised brick surrounds with projecting sandstone cills. Ground-floor windows have rusticated sandstone flat-arch heads of five voussoirs; first-floor windows have keyed flat-arch heads of three stones; basement openings have segmental brick arched heads with plain reveals, timber louvres, and projecting sandstone cills. Below the ground-floor windows in the wings and at the entrance gable are brick flat-arched recesses, presumably originally ventilators, now blocked with tinted render.

The west elevation of the central entrance block is a three-bay, two-storey red brick gable with rusticated sandstone quoins to the extremities, four rusticated pilasters to both storeys — the outer pair ending in sandstone blocks, the inner pair carrying a semi-circular sandstone panel inscribed 'Ishbel Aberdeen Pavilion' in incised characters — and a moulded sandstone coping to the gable. The central entrance is formed by a pair of modern rectangular timber glazed and panelled doors surmounted by a plain rectangular fanlight with a semi-circular fanlight above, all set in a rusticated sandstone surround topped by a shaped sandstone frieze and miniature swept triangular pediment. Five steps lead up to the front door, finished with later modern tiles. One window is provided to each side of the main entrance, with three windows to the first floor. The main entrance archway is abutted by a later open covered porch with iron posts; fretted wooden railings to the north side surmounted by modern glazing; a concrete ramp with modern metal railings to the south side; a hipped glazed roof surmounted by a scrolling ironwork finial; and part of an original ornamental cast iron ridge cresting, which connects to the central covered open corridor system in front of the building.

The north side of the central entrance block has a front plane two windows wide to each floor, with rusticated sandstone quoins to the right-hand extremity and raised brick quoins to the left, and a third bay of windows recessed to the left-hand side. The recess contains a circular window opening to the attic area, now bricked up; the west side of the recess is blank. The ground-floor window to the right-hand side appears to have been an original doorway later partly bricked up to form a smaller window. The south side of the central entrance block has similar elements to the north, except that the original recess has been filled in; at the base of the infill bay is a pair of small rectangular timber louvred doors to the basement, and the top of the infill wall rises above eaves level to a later flat parapet.

The right-hand wing of the main block is six bays wide, with a central two-storey bowed projection two windows wide. Between the windows is a central angled vertical brick moulding on a red sandstone corbel rising to meet a brick cornice with a ramped parapet above. The end gable is blank. A recessed single-bay link with one window to each floor in plain reveals connects to a projecting one-bay hipped end block with a blank wall next to the link and one window to each floor in the front face. The left-hand wing of the main block is a handed version of the right-hand wing, including link and end pavilion, except that a seventh bay with a window to each floor is hidden from frontal view in the recess behind the central entrance block. The north elevation of the northern end pavilion is blank.

The rear elevation is symmetrical and comprises a long two-storey gabled main block with a pair of deep projecting canted two-storey bays, and hipped end blocks joined by short links to each end. Roofs, walling, and window details are as on the entrance front, with all first-floor windows replaced by PVC. The canted bays have one window to each floor in their angled faces, with blank fronts and sides. Recessed in the main wall between the canted bays are three narrow windows to each floor, sashed as elsewhere but with later timber-framed mesh screens attached to top and bottom; the basement contains a pair of ledged timber doors approached by sunken steps. The main walls to each side of the canted bays are similar to the entrance front with central bowed projections, but overall five windows wide rather than six. End gables are blank. The recessed links are one opening wide, with a doorway on each floor: the ground-floor doorway is original, comprising a rectangular timber panelled door surmounted by a large plain fanlight with a rusticated sandstone flat-arch to the head; concrete ramps lead to each end block. The first-floor doorways each contain a rectangular flush timber door with a two-pane horizontally pivoting fanlight and a keyed flat arch, opening onto what appear to be later iron fire escape stairways. The east elevation of each end block has three windows to each floor; the two narrow windows on the ground floor of each end block have their rusticated sandstone heads cut from a single stone. The south elevation of the southern end block is blank.

PAVILION 2

Pavilion 2 is a two-storey building of red brick with sandstone dressings, of symmetrical frontage, comprising a central gabled three-bay entrance block projecting in front of a long rectangular block that extends to each side as two six-bay wings, each joined by short single-bay links to single-bay hipped end blocks. The main entrance faces east.

Roofs are of Bangor blue slates in regular courses with red ridge tiles. Three chimneys on the main ridge are of red brick with sandstone caps; pots are present only on the central stack. Walls, rainwater goods, window types, and detailing are as described for Pavilion 1. Below the ground-floor windows in the wings and at the entrance gable are brick flat-arched recesses, presumably originally ventilators, now blocked with tinted render.

The east elevation of the central entrance block is a three-bay, two-storey red brick gable with rusticated sandstone quoins to the extremities, four rusticated pilasters to both storeys — the outer pair ending in sandstone blocks, the inner pair carrying a semi-circular sandstone blind panel — and a moulded sandstone coping to the gable. The central entrance is formed by a pair of modern rectangular timber glazed and panelled doors surmounted by a plain rectangular fanlight with a semi-circular fanlight above, all set in a rusticated sandstone surround topped by a shaped sandstone frieze and miniature swept triangular pediment. Five steps lead up to the front doorway with original concrete finishes. One window is provided to each side of the main entrance, with three windows to the first floor. A modern PVC pipe is located alongside the left-hand upper window. The main entrance archway is abutted by a later open covered porch with iron posts, fretted wooden railings, modern glazed sides, and a hipped glazed roof surmounted by a scrolling ironwork finial and decorative cast iron ridge cresting, connecting to the central covered open corridor system.

The north side of the central entrance block has a front plane two windows wide to each floor, with rusticated sandstone quoins to the left-hand extremity and raised brick quoins to the right, and a third bay of windows recessed to the right-hand side. The recess contains a circular opening with a mesh grille and brick surround to the attic area; the east side of the recess is blind brickwork. The south side is of similar elements to the north, except that the original recess has been filled in; at the base of the infill bay is a pair of small rectangular timber louvred doors to the basement. The ground-floor window to the right-hand side appears to be an original doorway later partly bricked up to form a smaller window.

The left-hand wing of the main block is six bays wide, with a central two-storey bowed projection two windows wide, a central angled vertical brick moulding on a red sandstone corbel rising to a brick cornice with ramped parapet above, and a blank end gable. A recessed single-bay link with one window to each floor in plain reveals connects to a projecting one-bay hipped end block with a blank wall next to the link and one window to each floor in the front face. The right-hand wing is a handed version of the left-hand wing, including link and end block, except that a seventh bay with a window to each floor is hidden from frontal view in the recess behind the central entrance block. The south elevation of the southern end block is blank.

The rear elevation is symmetrical and comprises a long two-storey gabled main block with a pair of deep projecting canted two-storey bays and hipped end blocks joined by short links to each end. Roofs, walling, and window details are as on the entrance front. Two chimneys with pots, one rising from each canted bay. Canted bays have one window to each floor in their angled faces, with blank fronts and sides. Recessed in the main wall between the canted bays are three narrow windows to each floor, sashed as elsewhere but with later timber-framed mesh screens attached to top and bottom; the basement contains a pair of ledged timber doors approached by sunken steps. The main walls to each side of the canted bays are similar to the entrance front with central bowed projections, but overall five windows wide rather than six. End gables are blank. The recessed links are one opening wide, with a doorway on each floor: the ground-floor doorway is original, with an original rectangular timber panelled door surmounted by a large plain fanlight and a rusticated sandstone flat-arch to the head; five concrete steps serve the northern end block, and a concrete ramp the southern. First-floor doorways each contain a rectangular flush timber door with a two-pane metal horizontally pivoting fanlight above and a keyed flat arch, opening onto what appear to be later iron fire escape stairways. The west elevation of each end block has three windows to each floor; the two narrow ground-floor windows of each end block have their rusticated sandstone heads cut from a single stone. The north elevation of the northern end block is blank.

PAVILION 3

Pavilion 3 is a two-storey building of red brick with sandstone dressings, of symmetrical frontage, comprising a central gabled three-bay entrance block projecting in front of a long rectangular block that extends to each side as two six-bay wings, each joined by short single-bay links to single-bay hipped end blocks. The main entrance faces west.

Roofs are of Bangor blue slates in regular courses with red ridge tiles. Three chimneys on the main ridge are of red brick with sandstone caps and red pots. Walls, rainwater goods, window types, and detailing are as described for the earlier pavilions. Below the ground-floor windows in the wings and at the entrance gable are brick flat-arched recesses, presumably originally ventilators, now blocked with tinted render.

The west elevation of the central entrance block is a three-bay, two-storey red brick gable with rusticated sandstone quoins to the extremities, four rusticated pilasters to both storeys — the outer pair ending in sandstone blocks, the inner pair carrying a semi-circular sandstone blind panel — and a moulded sandstone coping to the gable. A modern rustic brickwork lift shaft is cantilevered out over the north side of the entrance block above the left-hand side of the gable. The central entrance is formed by a pair of modern rectangular timber glazed and panelled doors surmounted by a plain rectangular fanlight with a semi-circular fanlight above, all set in a rusticated sandstone surround topped by a shaped sandstone frieze and miniature swept triangular pediment. Five original concrete steps lead up to the front doorway. Originally one window was provided to each side of the main entrance; the left-hand one is now blocked with render at the top and opened at the base to accommodate a later lift. Originally three windows were provided to the first floor; the left-hand one is now blocked with render to contain a modern ventilator. The later lift opening at bottom left is enclosed in a modern glazed stud-partitioned porch of poor quality, with a slated roof and modern PVC rainwater goods. The main entrance archway is abutted by a later open covered porch with iron posts, fretted wooden railings, and modern glazed sides (the left-hand one now partly obscured by the lift porch gable), with a hipped glazed roof surmounted by a scrolling ironwork finial and decorative cast iron ridge cresting, connecting to the central covered open corridor system.

The north side of the central entrance block has a front plane two windows wide to each floor, with rusticated sandstone quoins to the right-hand extremity and raised brick quoins to the left, and a third bay slightly set back at ground- and first-floor level to the left-hand side in a later filled-in recess. The recess contains modern rectangular timber fixed lights with top-hung vents, concrete cills, a modern metal ventilator, all set in modern cement render, with PVC gutter and downpipe; no basement opening is retained. The attic storey of the recess contains a rectangular timber louvred opening with a concrete lintel. The main front plane contains two basement openings: the left-hand one retaining original timber louvres, the right-hand one blocked with render. The south side is of similar elements to the north, except that the bay next to the main block is an original recess of only slight set-back, and three basement openings all retain original timber louvres.

The left-hand wing of the main block is six bays wide, with a central two-storey bowed projection two windows wide, a central angled vertical brick moulding on a red sandstone corbel rising to a brick cornice with ramped parapet above, and an end gable that is blank except for a rectangular timber sheeted door at attic level opening onto the flat roof. A recessed single-bay link with one window to each floor in plain reveals connects to a projecting one-bay hipped end block with a blank wall next to the link and one window to each floor in the front face. The right-hand wing is a handed version of the left-hand wing, including link and end block. The north elevation of the northern end block is blank.

The rear elevation is symmetrical and comprises a long two-storey gabled main block with a pair of deep projecting canted two-storey bays and hipped end blocks joined by short links to each end. Roofs, walling, and window details are as on the entrance front. Two chimneys with pots, one rising from each canted bay. Canted bays have one window to each floor in their angled faces, with blank fronts and sides. Recessed in the main wall between the canted bays are three narrow windows to each floor, sashed as elsewhere but with later timber-framed mesh screens attached to top and bottom, and modern metal louvres; the basement contains a pair of ledged timber doors approached by sunken steps flanked by modern tubular metal railings. The main walls to each side of the canted bays are similar to the entrance front with central bowed projections, but overall five windows wide rather than six. End gables are blank except for the attic doorway noted on the entrance elevation. The recessed links are one opening wide with a doorway on each floor: the ground-floor doorway is original, comprising a rectangular timber panelled door surmounted by a large plain fanlight with a rusticated sandstone flat-arch to the head; five concrete steps serve the northern end block and a concrete ramp the southern. First-floor doorways each contain a rectangular flush timber door with a two-pane horizontally pivoting metal fanlight and a keyed flat arch, opening onto what appear to be later iron fire escape stairways. The east elevation of each end block has three windows to each floor; the two narrow ground-floor windows of each end block have their rusticated sandstone heads cut from a single stone. The south elevation of the southern end block is blank.

PAVILION 4

Pavilion 4 is a two-storey building of red brick with sandstone dressings, of symmetrical frontage, comprising a central gabled three-bay entrance block projecting in front of a long rectangular block that extends to each side as two six-bay wings, each joined by short single-bay links to single-bay hipped end blocks. The main entrance faces east.

Roofs are of Bangor blue slates in regular courses with red ridge tiles. Three chimneys on the main ridge are of red brick with sandstone caps, with pots only on the central stack; one additional chimney on the entrance block ridge, with pots. Walls, rainwater goods, window types, and detailing are as described for the earlier pavilions. Below the ground-floor windows in the wings and at the entrance gable are brick flat-arched recesses, presumably originally ventilators, now blocked with tinted render.

The east elevation of the central entrance block is a three-bay, two-storey red brick gable with rusticated sandstone quoins to the extremities, four rusticated pilasters to both storeys — the outer pair ending in sandstone blocks, the inner pair carrying a semi-circular sandstone blind panel — and a moulded sandstone coping to the gable. The central entrance is formed by a pair of modern rectangular timber glazed and panelled doors surmounted by a plain rectangular fanlight with a semi-circular fanlight above, all set in a rusticated sandstone surround topped by a shaped sandstone frieze and miniature swept triangular pediment. Five original concrete steps lead up to the front doorway. One window is provided to each side of the main entrance, with three windows to the first floor. The main entrance archway is abutted by a later open covered porch with iron posts, fretted wooden railings, modern glazed sides, and a hipped glazed roof surmounted by a scrolling ironwork finial and decorative cast iron ridge cresting, connecting to the central covered open corridor system.

The north side of the central entrance block has a front plane two windows wide to each floor, with rusticated sandstone quoins to the left-hand extremity and raised brick quoins to the right, and a third bay of windows recessed to the right-hand side. The recess contains a rectangular window glazed 3 over 3 (apparently a central pivoting window) with a plain concrete lintel to the attic area; the east side of the recess is blind brickwork at ground-floor level and glazed white tiling at first-floor level. The south side is of similar elements to the north, except that the original recess has been filled in at ground- and first-floor level; the attic of the recess contains a rectangular two-pane window with concrete lintel.

The left-hand wing of the main block is six bays wide, with a central two-storey bowed projection two windows wide, a central angled vertical brick moulding on a red sandstone corbel rising to a brick cornice with ramped parapet above, and an end gable that is blank except for a rectangular timber glazed and panelled door at attic level opening onto the roof of the link. A recessed single-bay link with one window to each floor in plain reveals connects to a projecting one-bay hipped end block with a blank wall next to the link and one window to each floor in the front face. The right-hand wing is a handed version of the left-hand wing, including link and end block, except that a seventh bay with a window to each floor is hidden from frontal view in the recess behind the central entrance block. The south elevation of the southern end block is blank.

The rear elevation comprises a long two-storey gabled main block with hipped end blocks joined by short links to each end, and one deep projecting canted two-storey bay to the right of a long two-storey rear return that contains an open vehicular archway. Roofs, walling, and window details are as on the entrance front. Two chimneys with pots: one rising from the canted bay, the other surmounting a gablet to the right of the left-hand bow.

The rear return is two storeys, carried over a vehicular driveway on a large semi-circular brick archway. The north side of the return has a hipped slated roof with terracotta ridge tiles, two chimneys with pots, walling, rainwater goods, and windows all as elsewhere. The elevation comprises a main face three windows wide to the first floor with one window to the left of the archway at ground-floor level, and a breakfront to the right containing a doorway and a first-floor window. The doorway is a rectangular timber glazed and panelled door with a two-pane timber fanlight above, leading onto what appears to be a later iron fire escape stairway; the window is tall, narrow, and sashed as elsewhere, with an opening light above. The west side of the rear return contains two windows to each floor: first-floor windows as elsewhere; ground-floor windows are later rectangular timber fixed lights with concrete lintels and brickwork cills set in plain brickwork filling in earlier semi-circular arched openings. The south side of the rear return contains the vehicular archway and an end breakfront as on the north, but without a recess; two later windows at ground floor fill in earlier semi-circular arches, and four first-floor windows have casements in place of sashed frames.

The canted bay on the rear elevation has one window to each floor in its angled faces, with blank front and sides. Recessed in the main wall between the canted bay and the rear return are three narrow windows to each floor, sashed as elsewhere but with later timber-framed mesh screens attached to top and bottom; the basement contains a pair of ledged timber doors approached by sunken steps. The main walls to each side of the canted bay are similar to the entrance front with central bowed projections, but overall five windows wide rather than six. End gables are blank except for the attic doorway onto the link flat roof noted on the entrance elevation. The recessed links are one opening wide with a doorway on each floor: the ground-floor doorway is original, comprising a rectangular timber panelled door surmounted by a large plain fanlight with a rusticated sandstone flat-arch to the head; five concrete steps serve the northern end block and a concrete ramp the southern. First-floor doorways each contain a rectangular flush timber door with a two-pane metal horizontally pivoting fanlight and a keyed flat arch, opening onto what appear to be later iron fire escape stairways. The west elevation of each end block has three windows to each floor; the two narrow ground-floor windows of each end block have their rusticated sandstone heads cut from a single stone. The north elevation of the northern end block is blank.

PAVILION 5

Pavilion 5 is a two-storey building of red brick with sandstone dressings, of symmetrical frontage, comprising a central gabled three-bay entrance block projecting in front of a long rectangular block that extends to each side as two six-bay wings, each joined by short single-bay links to single-bay hipped end blocks. The main entrance faces west.

Roofs are of Bangor blue slates in regular courses with red ridge tiles. Three chimneys on the main block ridge are of red brick with sandstone caps, without pots to the two on the end gables. Walls, rainwater goods, window types, and detailing are as described for the earlier pavilions, except where modernised. Below the ground-floor windows in the wings and at the entrance gable are brick flat-arched recesses, presumably originally ventilators, now blocked with tinted render.

The west elevation of the central entrance block is a three-bay, two-storey red brick gable with rusticated sandstone quoins to the extremities, four rusticated pilasters to both storeys — the outer pair ending in sandstone blocks, the inner pair carrying a semi-circular sandstone blind panel — and a moulded sandstone coping to the gable. A later glazed porch precedes the central entrance, which is formed by a pair of modern rectangular timber glazed and panelled doors surmounted by a plain rectangular fanlight with a semi-circular fanlight above, all set in a rusticated sandstone surround topped by a shaped sandstone frieze and miniature swept triangular pediment. One window to each side of the main entrance retains original timber sashes, the one to the right now partly enclosed by a modern corridor; three windows to the first floor have had their original timber sashes replaced by fixed lights with top-hung vents. A modern PVC pipe is located alongside the left-hand windows. The later porch has a glazed roof and front with a side entrance, timber fixed lights, modern flush timber glazed doors, six modern tiled steps, a rustic brick front plinth with dry-dash render of limestone chippings, and a hipped glazed roof surmounted by part of a decorative cast iron ridge cresting, connecting to the central covered open corridor system. Extending to the right of the later porch is a single-storey roofed block stretching across the rest of the building to the right-hand side.

The north side of the central entrance block has a front plane two window openings wide to each floor, with rusticated sandstone quoins to the right-hand extremity and raised brick quoins to the left, and a third bay slightly set back to the left-hand side in a later filled-in recess. The left-hand window openings in the front plane have been later bricked up; the right-hand ground-floor window is original, but the first-floor one has had its sashes replaced by a fixed light and a top-hung vent. The recess walling is of modern plain red brick with a rectangular flush timber door at ground floor and a modern rectangular fixed light with top-hung vent to the first floor. The south side is of similar elements to the north, except that the recess has been filled in with a modern red brick lift shaft rising to a flat roof, containing an attic opening with timber sheeted doors surmounted by a projecting steel girder. First-floor windows in the front plane have been modernised as on the north side; the ground floor is now absorbed in a modern flat-roofed block.

The left-hand wing of the main block is six bays wide, with a central two-storey bowed projection two windows wide. Ground-floor windows retain original sashes; first-floor windows have been modernised as elsewhere. The central angled vertical brick moulding on a red sandstone corbel rises to a brick cornice with ramped parapet above; the end gable is blank. A recessed single-bay link of later modern red brickwork with small rectangular PVC fixed lights with top-hung vents in plain reveals connects to a projecting two-bay hipped end block with two windows to each floor in the front face as elsewhere. The right-hand wing is a handed version of the left-hand wing, including link and end block, except that most of the ground floor is obscured by a modern single-storey flat-roofed block, with only the tops of windows visible on the exterior while the bottoms remain visible inside.

The north elevation of the northern end block contains one window to each floor; the first-floor window has been modernised as elsewhere; the ground-floor window appears originally to have been a doorway, with later brickwork showing the pattern of original brick quoins to the lower portion and the location of an original recessed step; it is now a timber fixed light with bottom-hung top vent in original surrounds, but with a concrete cill.

The rear elevation comprises a long two-storey gabled main block with hipped end blocks joined by short links to each end and a central two-storey rear return. Roofs, walling, and window details are as on the entrance front. The rear return is two-storey with a basement storey, hipped slated roof with ridge tiles, one chimney with pots, and walling, rainwater goods, and windows all as elsewhere. The north side comprises a main plane two windows wide, a breakfront to the right two windows wide, and a shallow recess to the left one window wide. Ground-floor windows in the main plane retain original timber sashes; first-floor windows are modern PVC replacements with top-hung central lights. The left-hand ground-floor window in the breakfront has been altered to create a doorway with modern glazed timber double doors opening onto a concrete ramp with tubular metal railings; a modern canopy over the ramp has timber fascia boards, a felt roof, and PVC gutter and downpipe. The east side of the return is two windows wide to each floor, windows as on the south side. The north side of the return is similar to the south but without the recess; the main wall has three large segmental-arched openings in rusticated sandstone to each floor. At first-floor level, from left to right: a pair of modern flush timber doors with plain fanlight opening onto a metal fire escape stairway, followed by two openings with coupled modern PVC replacement windows about a central mullion. At ground-floor level: two openings with coupled original timber sashes about a central mullion, followed by a later adaptation with a modern porch below a plain high-level fixed light, the porch leading to a glazed modern extension connecting to a modern single-storey brick building. A breakfront in the main wall to the right of the rear return contains three windows to each floor, sashed as elsewhere.

The main walls to each side of the rear return and breakfront are similar to the entrance front with central bowed projections, except that most of the wing to the north has its ground floor obscured from view by a later modern flat-roofed single-storey extension. End gables of the main block are blank. The recessed link to the south end has a doorway on each floor: the ground-floor door is original, with an original rectangular timber panelled door surmounted by a large plain fanlight, a rusticated sandstone flat-arch to the head, and five concrete steps. The first-floor doorway contains a rectangular flush timber door with a two-pane horizontally pivoting fanlight and a keyed flat arch, opening onto what appears to be a later iron fire escape stairway. The recessed link to the north end has a first-floor doorway only, the original ground-floor one now covered by the modern single-storey extension; the first-floor doorway contains a rectangular flush timber door with a two-pane horizontally pivoting fanlight and a keyed flat arch, opening onto what appears to be a later iron fire escape stairway. The east elevation of each end block has three windows to each floor, except that the northern end block has most of its ground floor abutted by the modern single-storey extension, leaving only three high-level openings at the heads of original windows: two containing plastic ventilators and one a top-hung metal window. The south elevation of the southern end block is similar to the north elevation, except that part of the ground floor including most of its window is obscured by a modern flat-roofed block.

PAVILION 6

Pavilion 6 is a two-storey building of red brick with sandstone dressings, of symmetrical frontage, comprising a central gabled three-bay entrance block projecting in front of a long rectangular block that extends to each side as two six-bay wings, each joined by short single-bay links to single-bay hipped end blocks. The main entrance faces east.

Roofs are of Bangor blue slates in regular courses with red ridge tiles. Three chimneys to the main block are of red brick with sandstone caps: one on each gable without pots, and one in the centre on the ridge with pots. Walls, rainwater goods, window types, and detailing are as described for the earlier pavilions, except where modernised. Below the ground-floor windows in the wings and at the entrance gable are brick flat-arched recesses, presumably originally ventilators, now blocked with tinted render.

The east elevation of the central entrance block is a three-bay, two-storey red brick gable with rusticated sandstone quoins to the extremities, four rusticated pilasters to both storeys — the outer pair ending in sandstone blocks, the inner pair carrying a semi-circular sandstone blind panel — and a moulded sandstone coping to the gable. The central entrance is formed by a pair of modern rectangular timber glazed and panelled doors surmounted by a plain rectangular fanlight with a semi-circular fanlight above, all set in a rusticated sandstone surround topped by a shaped sandstone frieze and miniature swept triangular pediment. Five original concrete steps lead up to the front doorway. One window is provided to each side of the main entrance, with three windows to the first floor. A modern PVC pipe is located alongside the left-hand upper window. The main entrance archway is abutted by a later open covered porch with iron posts, fretted wooden railings, modern glazed sides, and a hipped glazed roof surmounted by a scrolling ironwork finial and decorative cast iron ridge cresting, connecting to the central covered open corridor system.

The north side of the central entrance block has a front plane two windows wide to each floor, with rusticated sandstone quoins to the left-hand extremity and raised brick quoins to the right, and a third bay of windows recessed to the right-hand side. The recess contains a circular blind window opening with brick surround to the attic area; the east side of the recess is blind brickwork. The south side is of similar elements to the north, except that the circular attic window is glazed; the ground-floor window is partly obscured by a modern infill block in boarded timber with a metal window and PVC rainwater goods, and at the base of the infill block is a small timber sheeted door to the basement.

The left-hand wing of the main block is six bays wide as visible from the front, with a seventh bay hidden from direct frontal view in the recess behind the central entrance block; a central two-storey bowed projection two windows wide; a central angled vertical brick moulding on a red sandstone corbel rising to a brick cornice with ramped parapet above; and a blank end gable. A recessed single-bay link with one window to each floor in plain reveals connects to a projecting two-bay hipped end block with a blank wall next to the link and two windows to each floor in the front face, plus timber louvred basement openings in the plinth. The right-hand wing is a handed version of the left-hand wing, including link and end block. The south elevation of the southern end block contains one window to the first floor as elsewhere, and a doorway at ground-floor level containing a rectangular flush timber door with a plain fanlight, with a recessed high-level concrete step.

The rear elevation comprises a long two-storey gabled main block with hipped end blocks joined by short links to each end and a central two-storey rear return. Roofs, walling, and window details are as on the entrance front. The rear return is two-storey with a basement storey. The north side of the return has a hipped slated roof with terracotta ridge tiles, two chimneys with pots, walling, rainwater goods, and windows all as elsewhere. The elevation comprises a main plane three windows wide, a breakfront to the right two windows wide, and a shallow recess to the left one window wide. The west side of the return is two windows wide to each floor. The south side of the return is similar to the north but without the recess; the main wall has four large segmental-arched window openings in rusticated sandstone containing coupled sashed windows about a central mullion. The bay next to the main block has a plain flush doorway opening onto a modern concrete ramp; the top-left segmental-arched window contains a pair of flush timber doors opening onto what appears to be a later metal fire escape stairway. The breakfront in the main wall to the right of the rear return contains three windows to each floor, sashed as elsewhere but with later timber-framed mesh screens attached to top and bottom; the basement of the breakfront contains a pair of ledged timber doors approached by sunken steps.

The main walls to each side of the breakfront and rear return are similar to the entrance front with central bowed projections. End gables of the main block are blank. The recessed links are one opening wide with a doorway on each floor: the ground-floor doorway is original, comprising a rectangular timber panelled door surmounted by a large plain fanlight with a rusticated sandstone flat-arch to the head and five concrete steps to each end block. First-floor doorways each contain a rectangular flush timber door with a two-pane metal horizontally pivoting fanlight and a keyed flat arch, opening onto what appear to be later iron fire escape stairways. The west elevation of each end block has three windows to each floor. The north elevation of the northern end pavilion is similar to the south.

FORMER OBSERVATION PAVILION (NOW PART OF MONTGOMERY HOUSE)

The former observation pavilion is a single-storey building, now forming part of Montgomery House, consisting of the original Edwardian red brick observation ward block — which also contains a basement storey — with large modern extensions to the rear.

The main façade of the surviving original portion faces north and contains an entrance. The north elevation comprises a projecting gabled block to the right of a recessed entrance bay, three windows wide, and a hipped block to the left, also three windows wide. Roofs are of Bangor blue slates in regular courses with red terracotta ridge tiles. Walls are of red brick with projecting brick eaves courses, a projecting plinth, and projecting brick quoins to the extremities. Windows are original rectangular timber sliding sashes, 1 over 1 with horns, surmounted by bottom-hung toplights; projecting sandstone cills; rusticated sandstone flat-arched heads; both plain reveals and raised brick surrounds to reveals. Segmental arched heads to basement openings, with timber louvred and ledged timber doors. Rainwater goods are moulded cast iron gutters and cast iron downpipes.

The recessed entrance bay contains a later single-storey infill porch with a modern glazed timber door and plain sidelights; four original concrete steps serve the doorway. The north face of the hipped block has plain reveals to three windows; the east side has raised brick reveals to an original rectangular timber doorway with plain fanlight and a recessed concrete step, and to the left of this doorway is a pair of small coupled later metal windows. The north face of the gabled block has a shallow projecting curved bay with a ramped sandstone parapet, containing three original windows with raised surrounds, the two outer ones with flat-arched ventilator panels below them, later blocked up. The east and west sides of the gabled block each contain three original windows with raised surrounds, the southernmost of each now blocked with timber boarding. The rear elevation is now absorbed within the modern extensions.

FORMER STAFF HOUSE

The former Staff House is a two-storey red brick house of asymmetrical plan and plain character. The main entrance faces east.

The east elevation has a hipped roof of Bangor blue slates in regular courses with red tiles to the ridge of the hips, metal flashing to the main ridge, chimneys of red brick with sandstone haunching and red pots, and walls of red brick with raised brick quoins to the extremities and a projecting brick plinth. A moulded sandstone eaves course is provided, along with a stringcourse continuous as a first-floor cill. Rainwater goods appear to be moulded PVC gutters with square-section PVC downpipes. The main entrance comprises a wide rectangular timber panelled door with a plain rectangular fanlight, modern metal handle and letterbox, raised brick surround, two curved concrete steps, and a rusticated sandstone flat-arch head. Above the doorway at first-floor level is a rectangular timber sliding sash, vertically hung, 1 over 1 with horns, set in plain reveals with a keyed flat-arch to the head. To the left of the entrance bay is a shallow rectangular single-storey bay containing two windows with a lead-dressed hipped roof; windows are sashed as elsewhere, with plain reveals, projecting sandstone cills with brick aprons, and rusticated sandstone flat-arch heads. Above at first-floor level are two similar windows with keyed flat arches. To the right of the entrance bay is a canted two-storey bay with ramped sandstone copings to the parapet, one window in each face to each floor, windows detailed as elsewhere to the left-hand side of the entrance bay.

The south elevation has similar materials and details to the entrance front, with a two-storey canted bay to the right and two windows to each floor to the left, a cast iron soil pipe, and a doorway in the left-hand face of the canted bay at ground floor: a rectangular timber 18-pane glazed door with a plain rectangular fanlight and two semi-circular concrete steps. Extending to the left, set back slightly, is a single-storey gabled rear return containing one window as elsewhere at ground-floor level, with a slated roof, red ridge tiles, moulded cast iron gutter, and circular cast iron downpipe. Extending to the left, in the same plane, is a blank yard wall with shaped tile coping.

The rear elevation has similar materials and details to the front, with modern security bars to two upper windows, and cast iron and PVC downpipes. Projecting from the west wall of the yard is a later lean-to garage in red brick of light mottled tone to the south and west sides, with a roof of Bangor blue slates in regular courses, circular PVC gutter and downpipe, timber barge boards and fascia, a rectangular timber sheeted doorway in the south side, a three-light modern window in the west side with fixed lights and top-hung vent and a concrete cill and head, and a sliding glazed timber garage door in the north side, no longer functioning. The north wall of the yard contains a modern rectangular flush timber door approached by a concrete ramp with modern tubular handrails. The north elevation has similar materials and details to elsewhere, with a two-storey canted bay to the right projecting forward from the main wall, which contains a recessed entrance bay with a rectangular timber panelled door with surrounds, steps, and head as on the main entrance front. The building is surrounded by a tarmac area to three sides, with a stone chippings path across the south side leading onto a terraced lawn.

FORMER NURSES' HOME ('WEST HOUSE')

The former Nurses' Home, known as West House, is a building of two storeys and a basement in English Renaissance style, built of brick with sandstone dressings and laid out on a U-shaped plan. Designed by James R. Young of Young and Mackenzie, it was built in 1926. The main entrance faces north.

The entrance elevation comprises a long two-storey hipped-roof block with a large central projecting canted entrance bay and smaller canted bays to each end, with the main walls two windows wide between bays. The roof is of Bangor blue slates in regular courses. Four chimneys on the main ridge are of red brick with sandstone caps and original open-sided pots. Walls are of red brick with a projecting brick plinth, moulded sandstone eaves course, moulded sandstone stringcourse at first-floor level, and ramped sandstone copings to the parapets of the central and end bays. Rainwater goods are moulded cast iron gutters with cast iron downpipes. Windows are rectangular timber sliding sashes, vertically hung, 1 over 1 with horns, set in plain reveals with projecting sandstone cills; keyed sandstone flat-arch heads to the first floor; rusticated sandstone flat arches of five voussoirs to the ground floor and basement, except for the heads of narrow windows in the end bays, each cut from a single stone.

The main entrance comprises a pair of rectangular timber panelled and small-paned doors deep-set in a moulded lugged and heeled sandstone surround, with a pulvinated frieze and dentil cornice overlaid with a carved cartouche inscribed with the date 1926, all surmounted by a segmental pediment. This is located in a shallow breakfront whose first storey contains a window, sashed as elsewhere, set in a rusticated and lugged sandstone surround, all rising to a stepped segmental pedimented parapet containing the arms of Belfast sculpted in sandstone. A plain sandstone frieze and projecting chamfered sandstone plinth extend across the entrance bay. The main entrance is approached by a flight of eight rendered steps bounded by red brick dwarf walls with chamfered sandstone copings and modern tubular chromium handrails.

The east elevation is a long two-storey range with a basement storey where it returns from the entrance front. Roofing, rainwater goods, walling, and main windows are all as on the main block of the entrance front. The elevation contains two two-storey curved bays, each two windows wide, with curved glass and frames, curved sandstone cills, and rusticated heads. One doorway is provided at the right-hand end in the basement: a rectangular timber glazed and panelled door set in plain reveals with a plain concrete lintel, abutted by a glazed-roofed open passage constructed of iron posts and beams supported on red brick dwarf walls with chamfered sandstone copings.

The rear elevation consists of the south wall of the main block with a long wing returning at each end. The end elevations of the wings each contain a two-storey canted bay: the ground floor has two windows to the front face flanked by a single window in each angled face; the first floor has a single window in each angled face; windows are sashed as elsewhere with keyed and rusticated heads as elsewhere; the roof of each bay comprises hipped sandstone weatherings; a modern metal flue is present at the apex of the eastern wing's gable. The elevations facing onto the rear open area are plainer than the outer elevations: roofs and chimneys are similar, but walling is plainer, without a moulded cornice and with only short runs of moulded stringcourses to the southern end of each wing. Windows are sashed as elsewhere but set in brick flat-arch heads. The south wall of the front block is two-storey with a basement, containing two windows to each side of a single-storey canted bay with one window in each angled face and three in the main face. Projecting from the face of each wing is a short two-storey link, one window deep, connecting to a rectangular flat-roofed two-storey services tower each rising to a brick-encased water tank of utilitarian appearance. In each wing, a rectangular timber glazed and panelled door with plain fanlight opens onto an iron fire escape stairway.

The west elevation is a long two-storey range with a basement storey where it returns from the entrance front, with materials and detailing as on the east elevation but of plainer form, without curved bays.

LAUNDRY AND ENGINE HOUSE

The laundry and engine house is a single-storey red brick building of plain character with four gables to each end, and a later large single-storey flat-roofed extension along one side. Entrances to the laundry are on the north and east sides; the entrance to the engine house is on the west side.

Roofs are of Bangor blue slates in regular courses with continuous rooflights at the ridges. Walls are of red brick with moulded sandstone kneelers and plain sandstone copings to the gables. Modern steel ties are present to the engine house gable on the west elevation. Original window openings have segmental arched heads, plain reveals, and projecting sandstone cills; windows are mainly timber sliding sashes, 6 over 6 with horns, and also timber four-pane fixed lights. Doorways are rectangular, with modern flush timber doors and modern metal glazed doors in a modern metal glazed doorscreen. The west elevation also has a later high-level rectangular timber sheeted door surmounted by a projecting iron girder. A large brick chimney formerly stood attached to the east side of the boiler house. Detached to the east stands a single-storey gabled building of red brick with a later felt roof and later porch and canopy, originally the disinfecting house, now used as a staff tearoom.

---

MORTUARY

The mortuary is a single-storey gabled block of rectangular plan and plain character, built of red brick. The main entrance faces north.

The roof is of Bangor blue slates in regular courses with black ridge tiles. Two chimneys, one on each gable, are of red brick with sandstone caps and one pot each. Walls are of red brick with a projecting eaves course and a projecting plinth. Door and window openings have stop-chamfered reveals and rusticated sandstone flat-arch heads.

The north elevation has three doorways containing original rectangular ledged timber double doors with rectangular fanlights, the one at the extreme left having a fanlight of decorative Art Nouveau leaded lights. Four windows are provided: original rectangular timber sliding sashes, vertically hung, 1 over 1 with horns, with projecting sandstone cills and brick aprons. The window at the extreme left has decorative Art Nouveau leaded lights to each sash; the remaining windows have translucent glass. Rainwater goods are moulded cast iron gutter and downpipe. The east gable is blank. The west gable contains a later doorway at ground-floor level with a rectangular flush timber door, exposed iron girder lintel, and plain reveals; a modern flat canopy roof abuts at first-floor level, connecting with a modern single-storey red brick gabled block. The rear elevation contains original timber sashed windows, 1 over 1, with translucent glazing.

---

WORKSHOPS

The workshops form a two-storey red brick gabled building of plain character, used as joinery workshops. The roof is of Bangor blue slates in regular courses; windows are mainly later metal fixed lights and casements. One original feature survives: a pair of large double garage doors of ledged timber with multi-pane glazing, with a later wicket-door inserted. Later single-storey lean-to blocks abut the east and west sides.

---

SETTING

The hospital complex stands in a very rural setting characterised by dense woodland in part of the grounds, a substantial number of trees, shrubs, and hedges elsewhere within the grounds, and treed areas adjacent to the site. The main tarmac driveway winds up to the administrative block, bordered by original plantings and lawns extending to the central area between the ward pavilions and other buildings. Some post-Second World War residential and other blocks stand at the western end of the complex, with more recent buildings and a large tarmac car park at the south end.

At the end of a rear driveway stands a back gate known as the Ballylesson Gate, originally one of the entrances to Purdysburn House estate. It takes the form of a set of early Gothic Revival wrought iron gates with stone piers, built around 1825 to the design of Thomas Hopper, the architect of the contemporary Purdysburn House. The piers are now much overgrown with creeper, and one gate has had a wicket-gate for pedestrians cut into it with replacement metalwork.
