Atlassian plans to build the world’s tallest hybrid timber tower for its new headquarters next to Central Station, reshaping the skyline at the southern end of Sydney’s CBD. The 40-storey building will become the centrepiece of the state government-planned tech hub… Comprising mass timber and a facade of glass and steel, the building will feature a staggered outdoor garden as well as self-shading to control temperatures. Once complete in 2025, it will accommodate up to 4000 Atlassian staff, and a YHA hostel on its lower levels. …Atlassian, a global software giant, billed it as the tallest “commercial hybrid timber” building in the world at 180 metres high, and featuring a mix of outdoor and indoor areas. …Atlassian’s Scott Hazard said sustainability was a key focus for the tower, which would be built to last 100 years. “Cross-laminated timber is an incredibly green material, and it helps us avoid massive amounts of concrete and steel,” he said.
