Belfast Harbour Office

Belfast Harbour Office is a freestanding, symmetrical two-storey Italianate Palazzo style building with attic storeys to the wings and a partial basement, constructed in stages between 1852 and 1895. The east front was built around 1852 to designs by George Smith, Belfast's harbour engineer from 1839 to 1863, and the south entrance front and west wing were added between 1890 and 1895 to designs by the Belfast architect William Henry Lynn. The building is one of the finest architectural set pieces in the city, expressing the confidence and ambition of Belfast's industrial and commercial expansion, centred on its rapidly developing port. The listing extends to the building itself, its lamp standards, and the boundary railings.

George Smith (c.1792–1869) came to Belfast after working as engineer to the Leeds and Selby Railway, and during his tenure at the harbour he was responsible for major works including the cut that created Queen's Island, Clarendon Dock, Queen's Quay, and the timber wharfs along the River Lagan. The building was constructed on the former site of William Ritchie's shipyard. Ritchie (1756–1834), born in Ayrshire, had been invited to Belfast in 1791 and, with his brother Hugh, established the first major shipbuilding enterprise in the city. The decision to build the new Harbour Office on this site was taken in 1851, once the adjacent wet dock had been completed. Prior to this, the Harbour Commissioners had met at the Ballast Office, which was considered both too small and inconveniently positioned; it was subsequently demolished and replaced by the Custom House.

The original building cost £7,000 to erect and was valued at £460 in Griffith's Valuation of 1860. The second edition of the Ordnance Survey map of 1858 records only the south-east wing in existence at that time. The 1890–95 extension, designed by Lynn and carried out by builders H. & J. Martin, absorbed two-thirds of Smith's original block, though the seaward elevation remains largely intact. Lynn (1829–1915) had previously entered into partnership with Charles Lanyon in 1854; the firm of Lanyon and Lynn was responsible for numerous important civic buildings in Belfast, including the Custom House. After the partnership dissolved in 1872, Lynn practised independently and continued working into the early 20th century, notably completing an extension to Queen's University in 1910. The extension to the Harbour Office cost £14,369 in total and was opened on 18 January 1896, with the stated aim of achieving a level of splendour and grandeur befitting the confidence and success of Belfast's expanding port. It introduced the Ionic portico entrance, the Grand Staircase, and the immense Public Hall. The value of the building rose to £1,050 following the extension works, and to £1,650 by the First General Revaluation of Northern Ireland in 1935. A further and more disruptive phase of work came in 1971, when a modern extension was completed to the north of the Victorian blocks. This addition was named the William Ritchie Building in honour of the pioneer shipbuilder, and Ritchie is also commemorated by an Ulster History Circle plaque on its façade. Commentary on this extension has been unfavourable; it has been described as a mundane four-storey office block contributing little to the overall appearance of the site.

Architecturally, the building has been described as appearing as if it were standing in Florence, following the model of the Renaissance palaces of Italy — homes of the great merchants and financiers of early modern Europe — that was favoured for Belfast's mid-19th-century public buildings concerned with trade and commerce.

The building is located between Clarendon Dock and Corporation Square, overlooking Donegall Quay, and has a U-shaped footprint facing south. The east wing is wider and longer, and is attached by a link block to the modern northern extension. The west block is abutted to the rear by a lower return. The roofs are a complex arrangement of hipped and pitched natural slate with leaded hips and ridges, and pitched rooflights over the stairwells; all concealed behind a parapet. A stone cupola sits at the internal angle of the central and east blocks, with a polygonal leaded roof. It comprises a square ashlar sandstone base with filleted corners, carrying full-height round-headed 2/2 sash windows to each face — partially infilled with a timber-sheeted door to the east face — each flanked by pilasters that pierce a cornice and rise to a clock face (an ornate replacement stone carving survives over the south clock only). Above this is a polygonal lantern stage with rebated round-headed openings to each facet, impost mouldings, and keyblocks, topped by a moulded stone architrave and overhanging cornice. Tall ashlar sandstone chimneystacks of varied form rise from the parapet, with tapered stone caps. Rainwater goods comprise leaded parapet gutters and cast-iron downpipes.

All walling is ashlar sandstone except where noted otherwise. The ground floor is band-rusticated on a deep plinth, with narrow string courses at sill level and a heavy moulded string course between the floors. A heavy overhanging cornice supported on stone console brackets runs throughout, topped by attic storeys to the wings and a balustraded parapet to the central block and east elevation. The attic storeys have a dentil cornice and a balustraded parapet. Ground-floor windows are round-headed 1/1 sashes with panelled aprons set in alcoved surrounds with keyblocks. First-floor windows are rectangular side-hung casements with toplights, generally with projecting bracketed cills and pediments above. Diocletian windows appear at attic storey level, set in moulded reveals and surmounted with carved stone festoons.

The south entrance elevation is symmetrically arranged, comprising a recessed central block six windows wide, fronted by a portico and flanked by projecting wings with attic storeys. The portico is Ionic prostyle tetrastyle in antis, topped by a balustraded parapet, and reached by six stone steps; the antae have round-headed statuary alcoves with scallop shell motifs to their heads. A stone-flagged platform has a door at either end flanking three irregularly spaced casement windows with chamfered cills, and a coffered ceiling above. The principal access doors are double-leaf and half-glazed; to the right is a single varnished timber door. At the right end is a staged recessed opening descending to the basement; a window appears at the left end. First-floor windows on this elevation are arranged as an arcade, set in round-headed recesses with ornately carved tympana, archivolt, and keyblock. The flanking wings are three windows wide at each floor, with the outer first-floor windows carrying triangular pediments and the central ones segmental pediments on console brackets. The attic storeys are terminated by panelled piers supporting clustered chimneystacks; the Diocletian windows — leaded and stained to the west wing — are divided by dwarf piers.

The west elevation is symmetrical and dominated by a full-height bowed bay with a balustraded parapet. Detailing follows that of the south elevation, with three windows to each floor at the bowed bay flanked by two windows to either side. Cast-iron ventilation grilles appear at low level. The north elevation of the west wing is abutted by the lower return, which is plainly detailed with ruled-and-lined rendered walling and a plain parapet over a cornice, with a dentilled cornice between ground floor and mezzanine level and upper storey. Windows on this return are arranged irregularly to each elevation, all 1/1 sashes with plain reveals and a continuous stone sill course to the upper floor. A four-panelled timber door appears to the north, with a lift shaft extension and a modern glazed porch to the east.

The main rear (north) elevation is L-shaped, forming the rear of the central block and the west face of the east wing. Detailing here differs slightly, with a lighter cornice supported on small reeded brackets with paterae between and a dentil course below, and a balustraded parapet above with a continuous sill course to the first floor and chamfered sills to the ground floor. Windows have plain reveals and the plinth is tall and undercut. To the right side at each floor is a leaded-and-stained glass Serliana window; to the left are two round-headed windows above two pairs of narrow rectangular windows with multi-paned square lights over. A multi-faceted corner sits beneath the cupola. The west-facing section of this rear elevation has three 2/2 sash windows to each floor — the left-side first-floor window margin-paned — and camber-headed openings to the basement with plain rectangular openings to the right. The north elevation of the east wing is partly abutted by the modern extension; there is a single window to each floor at the right, two windows to each floor at the left, and multi-paned basement openings at ground level, with the right side blind. The east elevation is symmetrically arranged over the basement, with the cupola forming its central feature when viewed from this direction. It comprises a recessed central section four windows wide, flanked by projecting end bays one window wide. First-floor windows to the projecting bays have segmental pediments and balustraded balconettes; ground-floor windows have square-headed sidelights. The south cheek of the left projecting bay is one window deep, recessed behind the principal elevation when seen from the south.

The opulent interior is of particular note. The Board Room has been described as one of the handsomest rooms in Belfast, with excellent stucco design. The Grand Staircase and immense Public Hall were introduced in the 1895 extension, though the latter, along with the entrance hall, has been described as too consciously splendiferous. Of especial interest are the hand-painted stained glass windows, which give expression to the ideals of the Victorian industrial era in Belfast and represent the city's status as a centre of international trade and commerce.

The building is set on the west side of Belfast Harbour, accessed from Corporation Square, set back from Donegall Quay and forming part of the Clarendon Dock complex, which also includes two late 18th- and early 19th-century graving docks and the Clarendon Buildings. To the east is a car park and a vacant lot enclosed by steel security fencing, with views towards the Odyssey and Titanic Quarter. To the west is Sinclair Seamen's Presbyterian Church, and to the north are car parks and the Clarendon Dock development. The front of the building is bounded by cast-iron railings with matching entrance gates; similar railings terminate the entrance steps at granite pedestals supporting lamp standards.
