Photos: World’s tallest 39-floor hybrid timber tower reaches final construction phase

The Atlassian Central tower in Sydney is set to become the world’s tallest hybrid timber skyscraper, reaching 183 meters (600 feet) with 39 floors. Designed by BVN and SHoP Architects, the building employs a hybrid structural system combining concrete, steel, and engineered wood—specifically glued-laminated timber columns and cross-laminated timber slabs imported from Europe. This hybrid approach ensures the necessary stability for the tall structure, differentiating it from other timber buildings like Norway’s Mjøstårnet, which rely more heavily on timber alone. Sustainability is a core focus of Atlassian Central, which aims for a 6 Star Green Star rating and a 5.5 Star NABERS Energy commitment. The project has achieved a 50% reduction in embodied carbon compared to traditional construction methods and will operate on renewable energy. An advanced automated facade system with solar panels, window actuators, and extensive cabling is being installed to optimize natural ventilation and reduce mechanical
