International House Sydney

Barangaroo, Sydney

International House Sydney, a seven-storey commercial building designed by Tzannes for Lendlease, is now complete at Barangaroo South in Sydney. The timber structure building will be the first modern commercial engineered timber building of its size and type in Australia.

The building makes extensive use of structural engineered timber and recycled hardwood timber. We have turned the structural limitations imposed by the use of timber to advantage and celebrated them, forming a unique colonnade form evocative of a forest of trees which gives the building its distinctive character.

The result is a poetic and dynamic celebration of the building’s structural resolution, forming the street edge and undercover pedestrian network.

Watch the video that reveals how the building explores a new form of beauty, one of unique and integral character, with outstanding green credentials.
