EBSA - Australia
Atlassian Central has reached another significant milestone, with the world's tallest hybrid timber commercial building officially topping out at 39 storeys and more than 180 metres above Sydney.
Featured on Channel Nine News, the project continues to attract global attention for demonstrating what is possible when innovation, sustainability and collaboration come together on a large commercial development.
Developed by Dexus for co-owner Atlassian and delivered by Built in joint venture with Obayashi Corporation, the tower has been designed by SHoP Architects in collaboration with BVN. As the centrepiece of Sydney's Tech Central precinct, the project combines hybrid mass timber construction with an advanced operable façade strategy, targeting a 50% reduction in embodied carbon compared with a conventional commercial tower while operating entirely on renewable energy.
EBSA has been involved since the early contractor engagement phase, working alongside the project team to deliver the façade automation package that supports the building's natural ventilation and smoke relief strategies. Our scope includes:
• 4,757 CDC window actuators
• 18 CPS-M control panels
• 56 distribution boxes
• Approximately 42 kilometres of cabling
This represents the largest window automation package undertaken in Australia, to date, and reflects the importance of integrating automation early in the design process to support the building's ambitious environmental and operational performance targets.
Congratulations to Atlassian, Dexus, Built, Obayashi Corporation, SHoP Architects, BVN and everyone involved in reaching this outstanding milestone. We look forward to seeing the project completed in 2026.
