World's Tallest Timber Tower Tops Out at 591 Feet

A wooden skyscraper taller than a 50-story building just topped out in Sydney, Australia, proving that sustainable construction can literally reach new heights.

Atlassian Central soared to its final height of 180 meters (591 feet) this week, officially claiming the title of world's tallest hybrid timber tower. The 39-story building doesn't just edge out the competition. It smashes the previous record by more than double, towering over Milwaukee's Ascent tower, which stands at 86.6 meters.

The building uses roughly 10,000 cubic meters of engineered timber combined with a concrete core and steel exoskeleton. This hybrid approach gives the structure the strength it needs while delivering something remarkable: a 50% reduction in carbon emissions compared to traditional office towers.

"This is a moment of global significance," says Peter Titmus from BVN Architecture, one of the firms behind the design. The timber components arrived prefabricated, making construction faster, lighter, and cleaner than conventional methods.

Inside, workers will occupy most of the 39 floors, including a four-story collaboration space designed to flood the building with natural light. The tower will also house a hostel, multiple garden terraces, and a rooftop garden. Even an existing building on the site got new life, restored and woven into the lobby design.

The high-tech facade currently being installed incorporates solar panels and an automated cooling system, pushing the building's operational energy efficiency 50% beyond standard commercial towers.

The Ripple Effect

Atlassian Central represents more than just a record. It's a working blueprint for how cities can grow upward without destroying the planet in the process.

Every timber skyscraper that rises changes the conversation about what's possible in sustainable construction. Wood stores carbon rather than producing it during manufacturing, turning buildings into carbon sinks instead of carbon sources. As more architects and developers see timber towers succeeding at this scale, the approach becomes less experimental and more standard practice.

The project proves that environmental responsibility doesn't mean sacrificing ambition or capability. You can build tall, build fast, and build clean all at once.

Construction teams expect to complete the entire skyscraper by the end of 2026, adding a striking new landmark to Sydney's skyline and a powerful example to cities worldwide.
