1999 D Block. Description Adjacent to the Main Gate at the southeast end of George Street and on alignment with the Main Drive, the three-storey, facebrick, hip-roofed former Commercial and Day School overlooks the City Botanic Gardens. Each elevation is composed of light red facebrick with contrasting dark red facebrick relieved quoining, flat window arches and banding marking the floor levels. Prominent metal rainwater heads and downpipes divide the elevations into bays. The main elevation to the city Botanic Gardens is symmetrical about a narrow pedimented breakfront of dressed stone enriched with stone carving. The flat arched, central entrance porch with a prominent keystone in stone is flanked by posts with decorative carved shields to the capitals beneath an open-bed segmental pediment with decorative carving to the tympanum. A decorative metal grille fanlight sits over the porch entranceway. An arched porch entrance to the south opens onto the central courtyard and the arched entrance to the west connects with the new D Block undercroft link to F Block. There is a new metal bridge link across to B Block from the second floor. There are double hung windows to the ground floor of the front elevation with multi- pane casements to the upper floors. The other elevations have both double hung and multi-pane casement windows to each level. Originally each floor accommodated classrooms and staff offices off a central corridor from east to west meeting a transverse corridor running along the rear wing from north to south connecting with the walkways which in the original master plan were to link with adjacent buildings. The internal spaces have been altered and are now organised off the original corridors as large studio spaces and smaller office spaces. Some original joinery remains, including six-pane glazed doors to the ground floor and nine-pane glazed doors to the first and second floors, skirtings to the corridors, high timber rails to A208, timber rails at two levels in A204. The original stair to the ground and first floors of polished concrete with exposed aggregate remains and continues in plain concrete to the extension second floor. A decorative steel balustrade with timber handrail runs along the whole stair. Chemistry and Geology (E Block) Constructed: 1911-1914. Architect: T.
