Sydney's Atlassian Central: The World's Tallest Hybrid Timber Skyscraper

Sydney is constructing Atlassian Central, a 40-story hybrid timber tower reaching 180 meters. By using engineered wood combined with steel and concrete, the project aims to sequester carbon and reduce the high emissions typically associated with skyscraper construction. Designed by SHoP Architects and BVN, the tower is expected to be completed by 2026. It serves as a primary example of how mass timber can be scaled for high-density urban environments to lower the carbon footprint of the building sector.

Hybrid timber is a start, but the real question is the ratio of wood to concrete and steel. If the core is still massive reinforced concrete, the carbon savings are smaller than the headlines suggest. I want to see the actual embodied carbon LCA for this project.

Exactly. Until we have standardized reporting for embodied carbon in building permits, these projects are mostly marketing. We need procurement rules that mandate low-carbon materials rather than just celebrating a few trophy buildings.

2026 is an optimistic timeline for a project this complex. I wonder if the supply chain for the engineered timber is actually local or if they are shipping massive beams across oceans, which would eat into the carbon sequestration gains.

Interesting case for mass timber. It shows the tech is ready for height, but the cost premium usually keeps this out of standard commercial builds. Will be interesting to see if this actually moves the needle for Sydney's building codes.
