Glenwood Primary School, 4-22 Upper Riga Street, Belfast, Co Antrim, BT13 3GW

Glenwood Primary School was built in 1928 to the designs of R.S. Wilshere, architect to the Belfast Education Committee, whose work transformed school building design throughout the city. It stands on an expansive urban site between Tennent Street and Shankill Road in West Belfast, on ground formerly occupied by the Glenwood Corn and Flour Mill. The school is a largely symmetrical two-storey building arranged on a quadrangular plan, comprising four rectangular blocks orientated around a central open-air courtyard. The four blocks are connected at each corner of the quadrangle by flat-roofed, parapet-topped links containing stairs, secondary exits and service rooms. The courtyard has been partially infilled by an octagonal two-storey extension dating from around the 1960s, and further flat-roofed modern additions occupy the south-west corner of the original building.

Wilshere's plan is notably innovative: classrooms are arranged around the outer perimeter of the quadrangle, while an enclosed two-storey perimeter corridor runs around the inner courtyard elevation of each block. This corridor is lit at ground floor level by expansive timber-framed, segmental-arch-headed windows and at first floor level by square-headed casements, with a clerestory above. The arrangement ensures that both the classrooms and the circulation spaces are well lit and well ventilated — a direct reflection of Wilshere's commitment to fresh air and natural light, which was driven by health concerns about school buildings of previous decades.

Roofs are generally hipped and slated, with the entrance block to the west being gabled and featuring raised reconstituted stone verges. Dark roll-moulded ridge tiles are used throughout. Half-round cast iron rainwater goods are mounted on timber fascias at eaves level, with decorative cast iron hoppers and fixtures. External walling is of rusticated brick in Flemish bond with a soldier course at the base, and dressings throughout in reconstituted stone. Windows are large multi-light replacement timber casements set in reconstituted stone mullioned surrounds, painted white unless otherwise noted.

The principal elevation of the western block is three bays wide to each floor, with a projecting entrance bay at the centre that extends through two storeys with diminishing parapets breaking the eaves line. At first floor level this central bay features a large mullioned and transomed window, flanked either side by four-over-two-light windows with decorative brick and tile sills. The entrance itself is formed by an advancing, round-arched porch with a deeply recessed opening, chamfered jambs and an in-stepped head. The round-headed timber door has decorative moulding and is approached by steps and a ramp running along the left side of the elevation. A rectangular sandstone panel surmounting the entrance porch carries three carved figures. Either side of the central opening at ground level are two narrow blind loops with tile detailing, and a vertical window with glazing bars. Three expansive mullioned windows appear at both ground and first floor levels to each side, with metal grilles across some. The right gable of the western block is abutted by a modern extension of no architectural interest. The left gable contains a three-light rectangular mullioned window with a square rendered panel above inscribed 'TG', and a five-light window of similar style at ground floor level with blind openings to its lower half. A square brick chimney rises from the left side, and the flat-roofed connecting link to the north block abuts at this point.

The north elevation of the connecting link to the north-west has a round-arched recessed doorway similar to the main entrance, with a square-headed door surmounted by two mullioned two-over-four-light windows to the right. The canted left side is lit by two windows to each floor. The north block is detailed similarly to the west block but is asymmetrical, being five bays wide to each floor. The entrance, of the same character as that described above, is contained in a breakfront bay positioned second from the left, with a low parapet breaking the eaves. The original fixed lettering reading 'Glenwood Primary School' is retained over this entrance. The second opening from the right has been slightly remodelled to incorporate a door opening. To the left gable, a single-storey wall with a round-headed blocked opening abuts, with two first floor windows visible above and a restricted view of the ground floor. A pitched roof link corridor connects the north and east blocks, though this is not visible from the street. The eastern block is double height with a half-hipped roof structure; its right gable is blank. Five tall narrow casement windows with fanlights appear to the east elevation, and three similar windows with a larger central window are on the left gable. This block is abutted to the south by Tennent Street Baptist Church. It is attached to the southern block by a single-storey corridor that incorporates an exposed walkway at upper level.

The southern block has four expansive windows to each floor. Its right gable is abutted by the flat-roofed connecting link to the eastern block, which contains a recessed metal door surmounted by a window. The left gable is abutted by a modern extension that extends to the south-west and is of no architectural interest.

The inner courtyard elevations are broadly consistent in character, with square-headed windows at first floor level to the perimeter corridor, clerestory windows behind, and expansive timber-framed segmental-arched windows at regular intervals at ground floor level. Central openings in the corridor contain doors giving access to the courtyard. The enclosed corridor to the east is single-storey with an exposed walkway above. The centre of the west courtyard elevation is obscured by a modern two-storey extension that advances into the courtyard, accompanied by a brick storehouse and canopy; a further modern structure spans much of the north elevation above ground floor level. All these later additions are of no architectural interest.

The school is set within a large site and is accessed via two modern gates from Upper Riga Street at the north-west corner. A former pedestrian entrance to the north, with brick piers and a cast iron gate, is no longer in use. Playgrounds occupy the areas to the north, south and west of the building. The site boundary to the west is defined by modern railings, and to the north by a dwarf wall with cast iron railings. The elevated position of the western block affords views out to the surrounding hills. Neighbouring buildings to the south and east include Tennent Street Baptist Church. A secondary access from Shankill Road, comprising a gate with tall piers that passes beneath the modern two-storey extension, does not appear to be in current use. A two-storey caretaker's house of brick construction stands within the north-west corner of the grounds; it contains uPVC windows, doors and rainwater goods and appears to be of a later construction date than the school.

The school was built in response to the Education Act of 1923, under which the newly established Government of Northern Ireland — taking its lead from English educational reforms — made schooling compulsory for children aged four to fourteen. This drove a significant rise in pupil numbers, prompted the transfer of schools to the control of local education authorities, and led to a substantial programme of school building. Glenwood broke from the tradition of numerous small national schools by providing a large, purpose-designed building capable of meeting both the increased demand and the growing concern about health conditions in earlier school buildings. The First Revaluation of 1930 records it as a 'Public Elementary School, Yard and Grounds' with a rateable value of £609, in the ownership of the Belfast Regional Education Committee; prior to construction, the site had been recorded simply as 'building ground'. The school first appears on the fourth edition Ordnance Survey map of 1931 captioned 'Glenwood School'. During the Second World War the building served as a refuge for those displaced by German bombing raids and as a training base for the Home Guard. By 1950–51 it had become an intermediate school under the Belfast County Borough Education Committee, with a rateable value of £840. In 1967 it adopted its current name of Glenwood Primary School. During the 1950s and 1970s the building was substantially extended to the south-west, and the large octagonal gymnasium was constructed, partially infilling the inner courtyard. The Second Revaluation of 1956–72 lists the property at £3,544 and includes a caretaker's house and garden. Much of the original historic fabric and detailing survives, and the school remains a good example of its type by a notable and influential architect.
