The Treasury Building, or the Colonial Treasury Building, The Old Treasury Building, or the Treasury Building & Premier's Office, is a heritage-listed former government administration building and now hotel located at the junction of Macquarie and Bridge streets in the central business district of Sydney in New South Wales, Australia. Commenced in 1849 and completed in stages in 1851, 1853, 1900 and 1919 in the Victorian Neo-Classical and Italian Palazzo styles by NSW Colonial and Government architects Mortimer Lewis, Edmund Blacket, Walter Liberty Vernon, and George McRae, the building has been used variously by the NSW Treasury, the Audit Office, the Premier's Department, the Police Department, and the Ministry of Transport. In 1981 the building was sold to the InterContinental Hotel group, with a major hotel complex built on part of the site and much of the heritage building restored.

History

In 1849, just before the gold rush, a new building for the Colonial Treasurer and Auditor was commissioned from the Colonial Architect, Mortimer Lewis. The building, in the former garden of First Government House, was finished in 1851, with two frontages, one to Bridge Street for the Audit Office, the other to Macquarie Street for the Treasury. Its design owed a great deal to the Travellers' Club of 1829 in London's Pall Mall. The two separate offices were demarcated by an interior dividing wall. Lewis's successor, Edmund Blacket, added a coach-house and stables to the north by 1853.

The party wall was breached in 1873 when the Treasury took over the Audit Office's area, as well as erecting temporary buildings between the main offices and the stables. The Government Architect, Walter Vernon, added a large fire-proof Strong Room for the safety of documents in 1896–1898 to the north of the stables and in 1898–1900 he provided a Link Building, connecting the Strong Room to the Lewis building along Macquarie Street. This demolished the eastern part of Blacket's stables (and most of the western end went in 1967), leaving archaeological remains of significance. The present Macquarie Street portico dates to these Vernon works of 1898–1900. The Bridge Street wing was altered and extended for the Premier's Department in 1916–1919, to the design, as modified, of the then Government Architect George McRae. The Premier's Department continued to be there until 1967, when the State Office Block was erected.

Thereafter from 1967 until 1982, the Police Department occupied the Bridge Street space created by Lewis and McRae, while the Ministry of Transport had the Macquarie Street sector, where the Strong Room space had already been filled in during the 1940s. An auditorium for the Conservatorium of Music was constructed on the upper level of Lewis's building in 1977. Under Police and Transport, the buildings deteriorated, with undesirable changes to the fabric, until they were vacated in 1981. To accommodate a 31-storey hotel on the western part of the site, largely beyond the area protected by the PCO in 1985, conservation works were undertaken between 1981 and 1985. During 1983 archaeological work uncovered evidence of the 1850s Blacket stable block.

Description

The former Treasury building has fine Georgian elevations of exceptional scale, proportion and detailing. It occupies an important location in central Sydney. It contributes greatly to the sandstone townscape aesthetic of the Government precinct as well as being an excellent example of the craft work of its period.
