International House, Barangaroo, NSW

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

The six-story International House Sydney will be made from Cross Laminated Timber (CLT) and Glulam, setting a new benchmark for the use of sustainable materials. A striking colonnade of hardwood columns will front the street. Above those, all the floors will be CLT, the cores and lift shafts will also be CLT, while the columns and beams are Glulam and exposed around the lifts. Raking columns will be 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.
