The following excerpt is taken from a historic building survey of the site in 2017, prior to redevelopment. "The east and west extensions were designed by the architect G. Raymond and built by G. Segrue and built from 1930-31. The east extension measures 29m in length and 12m by width and is four storeys tall. It is built in an institutional classical style and four windows wide on the north elevation. There are two entrances into the building with the one on the east side the main entrance embellished with a cornice and the other through a two storey link between the original listed building and the new extension. The building has a flat roof behind a plain parapet with the building rendered on all elevations. The fenestration is more or less uniform with variegated sash type windows to the first, second and third storeys with the ground floor having modern replacement top opening four pane casement windows.
The exterior of the building is embellished with sections of moulded cornices on the east and west elevation returns intersected by the fourth storey windows. The interior of the building is dominated by the stairwell with access to all four storeys and leading off from the staircase are classrooms with tall ceilings and ample light from the large windows. On the ground floor is a large hall and stage.
The west extension measures 14m in length and 8.25m in width and has a more domestic design than its contemporary east extension. It is three storeys high with a pitched pantile roof pierced by a dormer on the west facade and is rendered on all elevations. The fenestration is uniform with variegated sash type windows on the three storeys. The main entrance is located on the south side up a flight of external iron stairs and into a central stairwell similar in scale the stairwell in the east extension. The interior rooms are uniform in design and decoration and are clearly institutional in appearance.
To the rear of the west extension is the chapel building which measures 21m in length and 14.50m in width. The building is two storeys high and has rendered exterior walls with a pitched pantile roof. The south elevation is apsed with two external brick buttresses and the central west façade embellished with a crucifixion tableau in stone set on a brick panel and topped by a barrel vaulted dormer dressed with lead sheeting. The fenestration on the ground floor is of timber casement windows with the fanlights divided by muntins. Two of the windows on the ground floor south elevation are pierced by fire doors.
The interior of the chapel building comprises classrooms on the ground floor and a chapel on the first floor with a white marble altar located in the west apse and with the roof structure partly exposed of laminated timber beams tensioned with diagonal steel rods.
The brick infill building built in the 1960s measures 11.50m in length and 6.50m in width and is wholly utilitarian in appearance with buff brick walls laid in a stretcher bond and exposed concrete lintels to the crittal steel windows on the first floor and UPVC replacement windows on the ground floor. The roof is flat and covered in mineral felt with no parapet and drainage to the west and east sides. The interior ground floor is an open space used as a reception with the first floor divided into offices" (from the original report, 1).
