354 George Street, Sydney, Heritage bank building in Sydney, Australia.

354 George Street is a heritage-listed former Bank of Australasia building designed by Edward Raht and completed in 1904. Its three street facades are built entirely of Bowral trachyte from Mount Gibraltar, with a rusticated rock-faced surface contrasting with a polished base. The facade shows Renaissance and Baroque influences, and the banking chamber inside is decorated with bronze, marble, cedar, wrought iron and gold leaf.

American architect Edward Raht designed the building in 1904 for the Bank of Australasia. It was among the first Australian structures with completely trachyte-clad exterior walls.

The building carries several names: Bank of Australasia, Australasia Chambers by 1940, 2 Martin Place, and 354-360 George Street. Ownership passed from the bank to Tenzon Pty. Ltd. in August 1980, then to the United Permanent Building Society weeks later, to the Government Insurance Office in 1984, and today to Paspaley Pearls Properties. The banking chamber kept its patterned interlocking rubber flooring, bronze, marble, cedar and gold leaf.

The building now houses professional offices while preserving its original banking hall, which remains visible to visitors. Historic details are easily seen from the street and its George Street location makes it convenient to access.

The trachyte for the walls came from the Bowral quarries on Mount Gibraltar, owned by the contractors Loveridge and Hudson. These were the first buildings with entire external walls of trachyte, a stone usually reserved for arches and columns.
