Turning the building inside out.

Brief

The Old Treasury Building of Perth required a renewal of its interiors and overall layout. While it has served its purpose well, several of its spaces and functions were dated—and newly updated facilities and open workspaces in need. New design touches were also placed upon its internal layout and façade to elevate its architectural presence in Perth’s urban city centre skyline.

Solution

For the re-design of the Old Treasury Building (it was originally created by Kerry Hill Architects), we worked closely with a contractor at the tender design stage to create a pragmatic and cost-efficient proposal. We looked at simplifying the layout of spaces and circulation of the building and decided to re-think the lift cores throughout the building. By reducing the number of lifts in operation, we were able to free up further open workspaces for the building’s inhabitants. The structural skeleton of the building was a focal element of our proposal and is expressed on the building’s façade. Encased within a sleek glass curtain wall system, the building is also elevated on a raised platform. The platform is a finely engineered braced frame that opens up the spaces on ground level onto the new public plaza adjacent to it, all while revealing the breathtaking heritage frontages of the original Treasury Building.
