International House Sydney, NSW

The first commercial office building in Australia made completely from timber has been built by Lendlease as the gateway to the Barangaroo development in Sydney.

The six-story International House Sydney is made from Cross Laminated Timber (CLT) and Glulam, setting a new benchmark for the use of sustainable materials. A striking colonnade of hardwood columns front the street. Above those, all the floors, cores and lift shafts are CLT, while the columns and beams are Glulam which are exposed around the lifts. The raking columns are made of Ironbark reclaimed from old bridges, mostly in Queensland and a few in Goulburn.

Lendlease’s Barangaroo South managing director Andrew Wilson said that they were on the way to creating Australia’s first large scale carbon neutral community. “The source of materials is important. To use at scale, timber is the only renewable resource,” he said.

In addition to a much lower carbon footprint, the use of engineered timber will also help to produce zero waste, a safer environment and a significant reduction in construction time.
