Restoration of this heritage building included the addition of two occupiable floors at the top of the building within a two-storey, steel-framed, glass roof dome and the installation of two unique glass shuttle lifts from the ground floor banking chamber to levels 10 and 11. 
The glass roof dome as installed was a triple-laminated glass with an aluminium mesh installed between layers one and two of each glazing panel. The dome roof consisted of more than 1000 panels, each individually installed by tower crane. This glazing created significant benefits from an ESD and thermal comfort perspective as the Solar Heat Gain Coefficient was as low as 0.18 for the meeting room glass. 
Two custom-made all glass circular elevators were designed to suit the existing heritage interior by concealing the elevator machinery and components. Each lift car was pre-assembled in Switzerland and transported to Australia as a single unit. 
The design development, manufacture and installation of this glazing and use of glass to an exceptionally high standard achieved by Brookfield Multiplex Constructions make this building a worthy winner of the Best Use of Glass award.
