The metamorphosis of the 1850s Mint from a cluster of ruinous and neglected shells to a superb ensemble of restored, adapted and invented forms and spaces... [is] a gift to Sydney... an exemplary collaboration of minds and skills: talented design architects, gifted specialist consultants and a client with a reputation for expertise and innovation in such projects.
— RAIA Jury

The once vacant and almost ruinous Mint Coining Factory and associated buildings, located behind the Mint Offices on Macquarie Street, were transformed into a campus-like headquarters for the Historic Houses Trust.

Facilities include an exhibition space, flexible theatrette/function space, bar, library, and contemporary workplace, all created by adaptively reusing existing buildings and sensitively inserting contemporary architectural forms.

The project has received many awards including winning the RAIA’s Sir John Sulman Medallion for Outstanding Public Architecture and the Francis Greenway Award for Conservation simultaneously (for the first time in the Institute’s history), and the Lachlan Macquarie Award for Heritage. It was also nominated by the UK’s Building Services Journal as one of the “top 30 ground breaking buildings of the world”.
