Blocks A and B are long, highset, prefabricated timber-framed buildings with gable roofs that continue over the north-facing verandahs.
A first floor covered walkway connects Block A with Block B to the south.
Both blocks have later extensions to the west (Block A, 1977; and Block B, 1962), which are not the Boulton & Paul type and are not of state cultural heritage significance.

The building exteriors are clad in timber chamferboards, including the southern and eastern sides of the understoreys, with the Boulton & Paul sections clearly distinguishable from later sections by vertical timber strips that define each panel of the prefabricated wall units on the first floor.
The eastern end of Block B is clad in modern corrugated metal.

Large areas of timber awning windows, with fanlights, line the southern Boulton & Paul walls, with brackets attached to the mullions and supporting the overhanging eaves.
The verandahs have timber floors, continuous timber posts, flat-sheeted raked ceilings and enclosed balustrades, which are either clad in chamferboards (Block A) or profiled metal-clad bag racks (Block B).

The Block A-B walkway aligns with the similar Block B-D walkway to the south.
The highset covered walkways have continuous timber posts, railed balustrades, timber floors and flat roofs with flat-sheeted ceilings.

The understoreys have concrete floors, and combine open play space with enclosed areas for various uses.
The floor structure of the classrooms above is exposed, with timber bearers supported on concrete piers.
Windows on the eastern and southern sides are a combination of louvred (Block A) and latticed (Blocks A & B).
