International House, in Sydney Australia, is the world’s tallest engineered timber commercial office building. Designed by Tzannes in Sydney, the building has 6 floors of commercial office area which are constructed from timber, including floors, columns, walls, roof, lift shafts, egress stairs and bracing bays, supported by a single ground retail level of conventional concrete structure.
Around 3,500 cubic metres of sustainably grown and recycled timber were used in construction. By not using concrete, thousands of tonnes of greenhouse gases were avoided.
International House is part of the most important reinvention of Sydney’s historic centre for decades names ‘Barangaroo’. The precinct is a globally significant, 22-hectare, $6+ billion waterfront renewal project that redefines the western edge of Sydney CBD's waterfront. It will be a lasting legacy of 21st Century urban renewal for future generations.
When finished in 2024, half of Barangaroo will be public space, encompassing a continuous 2km waterfront walkway, new parks, plazas and coves – all connected to the central business district and wider Sydney through new transport links, including a ferry hub and a Metro station.
