The Department of Treasury and Finance performs its operations in two main buildings:
1 Treasury Place
1 Macarthur Street
Barry Patten designed 1 Treasury Place and built it in the 1960s according to the Internationalist style of architecture.
The building is also on the Victorian Heritage Register.
Since a skyway connects 1 Treasury Place to 1 Macarthur Street, both are often considered to be part of the same building.
The whole area linking Parliament House, St. Patrick's Cathedral, Fitzroy Gardens, and Treasury Gardens is called the Treasury Reserve, a heritage-listed precinct.

Before 1878, the Victorian Treasury was situated at the corner of Spring Street and Macarthur Street.
When the state treasurer and his officers moved to Treasury Place, the old building was renamed the Old Treasury.
Old Treasury was widely regarded as the finest 19th century public building in Australia.
Upstairs in the building, Treasury officials kept the colony’s accounts.
Below, in the basement, were bluestone vaults for storing the gold sent by government escort from the goldmining fields.
