The Depression-era brick school building is a long, two-storey building with a full undercroft.
The building faces southwest and, as the undercroft is below the level of Bayswater Street, it is accessed via a wide walkway and steps to the main entrance in the centre of the first floor facade.
Symmetrical in plan, the building comprises a long central wing with projecting entrance bay, flanked by shorter wings to the northwest and southeast, which are parallel but set back from the central wing.
Secondary entrances are located at the corners of the intersecting wings, with stairs leading to first floor porticos at the front of the building, and ground floor porticos leading to the undercroft at the rear.
A two-storey extension (1959–60) which adjoins the southern end of the block is not of heritage significance.

Ornamented with a Spanish Mission-style decorative treatment, the building is constructed from red face brick walls with rough-cast concrete render to the entrance bay walls and smooth render to undercroft walls, window sills and lintels, and panels below the first and second floor windows.
The second floor has arched windows to the entrance bay, main façade of the central wing, and to the stairwells and corridors on the east elevation, constructed from semi-circular brick arches with brick or concrete keystones.
The entrance bay features a cantilevered balcony over the main entrance door, accessed by French doors, and a decorative parapet with small louvred ventilation panel.
An un-rendered version of this parapet also ornaments the northeast side of the central wing.
Early iron balustrades survive on the balcony; along the entrance walkway; and to the secondary entrance stairs.
The hipped roof is clad in terracotta tiles, and the raked eaves are lined with timber V-jointed (VJ) tongue and groove (T&G) boards.
First and second floor windows along the northeast elevation are protected by hipped window hoods clad in terracotta tiles and featuring decorative timber brackets.
The northwest and southwest end walls of the wings are largely blank.
An early school bell is fixed to the underside of the first floor window hood in the centre of the northeast elevation.

Windows openings are regularly spaced and generally comprise three tall casement windows with square fanlights above.
Arched windows have a fixed, semi-circular fanlight.
Walls to the toilets in the undercroft have high rectangular openings which formerly contained fixed louvres in timber frames, however the glass has been removed and modern screens fixed to the outside.
The main entrance double door, set back from the front façade, is a panelled, low-waisted door glazed with six-lights and retains early door hardware.
The secondary entrance doors to the first floor have been replaced, but retain their original two-light fanlights with patterned glass.

Non-significant features of the exterior include: a lift attached to the northwest wall of the central wing; air-conditioning units, cables and ducting; modern downpipes and rainwater tanks; and modern doors, gates and screens to doors and windows of the undercroft.

Internally, rooms are arranged along the northeast side of the wings, linked by wide corridors along the southwest side.
Vertical circulation is provided by stairwells at each end of the central wing.
Next to the stairwells are rectangular rooms formerly used for play space on the undercroft level and hat and cloak rooms on the upper levels.
The entrance bay contains rooms of varying size used for staff and office purposes.

The undercroft contains toilets in the northwest and southwest wings and was originally open play space in the central wing; however, in 2017 the southern portion of the space is enclosed for a tuck shop and music room.
This level has a concrete floor with coved edges, rendered masonry walls with rounded corners, and flat rendered ceilings.
The toilets largely retain their original layout; partition walls (some with high openings with wire grille infill panels); and flat-sheeted ceilings with batten cover strips.
