The main building at Graceville had a butterfly roof formed with a reinforced concrete slab lined with bituminous felt and supported on ten pre-cast, reinforced concrete beams that cantilevered off a continuous lintel resting on ten brick piers. A range of materials were used to fill the gaps between the brick frame: including orange-coloured face brick, screened openings, some small sections of render and various aluminium-framed windows. On either side of this building, two wide butterfly-roofed, steel-framed shelters with built-in seating were erected. Each was made up of four sets of steel columns and cantilevered steel tapering I-beams bolted together. The seating, made with timber slats and a steel and timber frame, was placed back-to- back facing each track. Dividing each row of seating were metal ribbed screens. Fitted to each steel column and under each beam were panels framed in steel and filled with glass above the seat level and sheet steel below. The other narrower platform necessitated smaller butterfly-roofed awnings be built there. They were essentially the same construction as the larger ones with only three bays, two of which were given over to seating. The subway system with its street ramps and stairs to both platforms was constructed with reinforced concrete.
