Details emphasize the tower’s height, design intent, and its potential impact on Sydney’s architectural landscape.

Locational impact places the tower in Sydney’s Central Station area, where it will dominate the skyline and influence the city’s tech precinct.

Atlassian’s Central tower in Sydney has structurally topped out, reaching the highest point of a 39-storey building designed as the world’s tallest hybrid timber structure, dubbed a ‘plyscraper,’ with the core now at the skyline’s peak.

Designed by BVN and SHoP Architects, the tower features open, interconnected workspaces, floating timber floors, and a central park-like atrium intended to redefine in-office work versus remote arrangements.

At street level, a reconstructed Parcels Shed will house a 480-bed YHA youth hostel, and the build uses 10,000 cubic metres of timber from Austria, 8,000 tonnes of steel, and 30,000 cubic metres of green concrete.

Practical completion is anticipated by year’s end, with central services underway and the build marked by a traditional evergreen tree topping ceremony.

A note from Atlassian leadership, including Mike Cannon-Brookes, reflects growth and ongoing commitment to the new HQ despite a workforce reduction of about 1,600 employees.

The tower combines mass timber, steel, and concrete, featuring four-storey timber ‘habitats’ within a steel exoskeleton to enable natural ventilation and a connected, city-integrated workspace.

Valued at about $1.45 billion, the project positions Atlassian as the flagship tenant at Tech Central, with other tech firms taking space and a smaller footprint than initially planned.

The project is described as set to become the world’s tallest hybrid timber building.

The project sits within Atlassian’s broader development and Sydney’s construction boom, highlighting milestones in architecture and engineering.
