Project Background

The three interconnected buildings, known as the State Buildings, lay empty and unused for nearly two decades before being reimagined and reinvigorated.

Over their 140-year history, the State Buildings (formerly known as the Old Treasury Buildings) have been used as public offices, a police court and cellblock, Treasury, Survey Department, GPO, immigration offices, Office of the Premier and Cabinet, Lands Department and titles building. However, towards the end of the 20th century, the buildings were vacated and stood empty for nearly two decades.

Project Details

One of the fundamental design principles was to ‘return’ the buildings to the public through creating a series of well-designed public places on the ground floor.

After some 15 years of complex planning discussions with successive state governments, we established our world-leading design team, including Kerry Hill Architects and Spaceagency. 

The focus of the project was to maintain as much heritage fabric as possible and further reinstate any heritage characteristics that had been lost over time. On completion of the project, 95 percent of the original buildings were maintained, with almost all original lost elements reinstated.

The project called for a sustainable approach in all areas, including adaptive repurposing of heritage buildings and materials.
