Atlassian Sydney Headquarters

“We have worked with some of the world’s best structural engineers Eckersley O’Callaghan and TTW to develop the structural solution. This will be the tallest hybrid timber structure in the world.” BVN co-CEO Ninotschka Titchkosky

Located in Sydney's CBD new Innovation and Technology Precinct.

Located in Sydney’s new Innovation and Technology Precinct, Atlassian Sydney Headquarters will be a 40-storey building at approx. 180 metres tall and includes a youth hostel occupying the lower levels.  To be completed by 2025 and attracting 25,000 workers, the new 40,000m2 world-first commercial tower is a groundbreaking global first.

The benchmark design of timber, with a glass and steel facade, includes a mix of outdoor and indoor spaces, and reaches over 40 storeys high. The State Significant Development’s design includes lateral stability, steel composite design, timber design and exoskeleton steel design. Being directly adjacent to platform 1 at Central Station, the development required approval from Transport for NSW (TfNSW). Expert in transport and infrastructure, TTW is the TfNSW Approved Engineering Organisation (AEO) for the project.

Unique design features include:

  • 4 storey CLT timber buildings with multiple cantilevers
  • Steel Exoskeleton with mega transfer to core
  • Heritage lower levels that allow for reinstatement of the parcel shed
  • Retention and excavation adjacent platform 1 central station
  • Tunnelling underneath Devonshire pedestrian tunnel
  • Building in a live environment including rail and pedestrian tunnels

TTW overcame many challenges such as large overturning moments due to gravity. This was avoided by repositioning the core which eliminated the need for ground anchors and pulled out significant concrete volume.

The project has ambitious targets for Sustainability; 50% less embodied carbon in construction compared to a conventional building. 50% less energy consumption compared with a new conventionally operated building and solar panels in the vertical facades, to generate green power on-site. Also, the building will operate on 100% renewable energy from day one and include solar panels built into the facade.
