Australia’s first cross-laminated timber commercial office building is on pace for completion next year in Sydney.
To be called International House Sydney (IHS), the six-story structure and Glulam building will be located at the gateway to Lendlease’s multi-billion dollar Barangaroo development and will be the construction firm’s third project in Australia that utilizes the sustainable building material, reports website Architecture and Design.
The building has been designed by Sydney architect Alec Tzannes, of Tzannes Associates, and will feature a clear-glass skin, leaving the engineered timber, including 2,000 meters³ of cross-laminated timber, in full exposure as floor frames, beams and columns.
The 7,910-square-meter office will sit behind the three “International Towers” designed by Rogers Stirk Harbour at Barangaroo South, which was recently awarded a 6-Star Green Star - Communities rating by the Green Building Council Australia.
IHS will be targeting a 6-Star Green Star Office Design and As Built (v3) rating of its own and its heavy dosage (not literally) of CLT will be a key factor in it achieving that. According to Lendlease's Barangaroo South managing director Andrew Wilson, all engineered timbers will sourced from sustainably managed forests in Austria and the timber will have a PEFC chain of custody certification.
That is expected to go a long way to lowering the building’s carbon footprint, which, according to Tzannes, is the driving force behind the project.
"The architecture of International House Sydney reflects a new form of beauty,” he said.
“Beyond shape and surface, it is 'deep design' renewing architecture's role to serve the greater social purpose of lowering carbon emissions.”
The building will be built on a concrete slab and share a basement with the International Towers behind.
This will be Lendlease’s third CLT project after the 10-story Forte apartments, Australia’s first CLT building, and the public Library at the Dock, in Melbourne's Docklands, which is Australia’s first public CLT building.
