The skyline in Sydney, Australia, is undergoing a transformation as Atlassian Central nears completion. This ambitious “plyscraper” is set to become the world’s tallest hybrid timber tower, reaching a staggering height of 183 meters. For comparison, the previous record-holder, Milwaukee’s Ascent, stands at 86.6 meters. Designed by BVN and SHoP Architects, the tower utilizes a hybrid structural system that combines concrete and steel with engineered wood. …While buildings like Norway’s Mjøstårnet rely more exclusively on timber, Atlassian Central incorporates significant steel and concrete components. This combination provides the structural stability required to support a 39-story frame. The project incorporates approximately 10,000 cubic meters of engineered wood. This includes glued-laminated timber columns and cross-laminated timber slabs, which are being imported from Europe. These timber elements are integrated into the floor plates and internal support structures of the tower.
