Alterations to the building Between 1974 and 1980 the Reserve Bank was extended to the south, this extension to the original building involved substantial additions on each floor to incorporate the adjacent site to the south. The site consisted of two properties Washington House and Federation House, both properties were demolished for the extension. The addition replicated the original building in height, form, and finishes. From 1991–1995 upgrading of offices and basement areas, removal of asbestos requiring the stripping of all internal finishes, upgrading of building services and fire protection facilities, new ceilings, lighting and carpets and the extensive restoration and recladding of the external facade of the building. In November 1993 the original facades were overclad. The original Wombeyan marble cladding was deteriorating due to a combination of weathering and pollution. The new facade was a combination of Australian and Italian stone, with the original Imperial Black granite from South Australia being used for the Columns and Italian Bianco Sardo grey granite for the spandrels. The work was designed by Arup Facade Engineering and was designed to have a minimum visual impact on the building. At the same time, the eastern end of the ground floor was modified from a banking chamber to form the public exhibition area. In 2000 the Parliamentary Committee on Public Works approved changes to the building included conversion of the staff cafeteria, auditorium and staff facilities (level 3) to office accommodation; demolition of the two residential flats and creation of new cafeteria space; removal of the two squash courts and plant equipment (level 17) and conversion to office use including lowering of the high level windowsills to the north
