Description The Reserve Bank building is at 65 Martin Place, corners with Macquarie and Phillip Streets, Sydney, a prominent corner position fronting Martin Place between Macquarie Street and Phillip Street. The Reserve Bank 1964, is a refined example of the Post War International style. The building is a 22-storey high-rise tower with three-level basement. It is constructed of a steel frame concrete encased with reinforced concrete slabs. The building contains some unusually long cantilever beams on the 1st to 3rd floors. The Reserve Bank provides a notable example of a characteristic of buildings of this era on less constrained sites, where the architect utilised the opportunity to define the base from the shaft using a podium. The Reserve Bank has a four-storey podium divided into two upper floors with projecting horizontal fins and two floors of full height recessed glazing to the mezzanine below. The building is entered via a bronzed railed grey and black granite terrace with steps to accommodate the site slope and adjacent footpath. The tower section above the second floor is set back from the site boundaries on the three street frontages. The rectangular building floor plate surrounds a central bank of lifts. The tower is capped with recessed balconies to level 20. Above this is a roof terrace with full height glazing and extensive cantilever roof. The facade treatment of the building is distinctive and derives from both the modular design created to allow office subdivision which is expressed in the window mullions and the use of materials including the extensive use of natural stone. The vertical columns faced in black granite and aluminium define the eight bays of the tower and extend up to form the supports for the balconies. The use of black polished granite cladding was a popular choice of the time, the Reserve Bank used Imperial Black granite for the columns. The subdivision of the facade into smaller vertical bays was characteristic of buildings where sun control was a central concern. Between the columns spandrel panels in grey granite alternated with recessed glazing. The glazing panels stop short of the corner. The basements contain vehicular access areas, the main switchboard as well as the three main strongrooms and a series of voucher
