The structure will incorporate 7,640 m³ of CLT floor slabs and 4,220 m³ of GLT glulam. These large timber elements will substantially reduce the building's overall carbon footprint, and the entire structure is wrapped in a steel exoskeleton.

The building is designed as seven timber "habitats," each consisting of four timber-framed levels with a naturally ventilated park. The ventilation strategy extends throughout the mixed-use spaces adjacent to each ventilated park, enhancing both sustainability and occupant comfort.

The CLT used in this project receives UV protection and water-repellent coatings on a fully automated coating line.

Manufacturing the CLT elements from PEFC-certified timber produced only 402 tonnes of greenhouse gas (CO₂) emissions. By contrast, 5,821 tonnes of carbon dioxide have been removed from the atmosphere and stored in the timber frames of the floors and roofs.

By substituting CLT for mineral-based materials such as concrete or structural steel, the project avoids an additional 8,732 tonnes of CO₂e in embodied emissions.

The primary reason CLT was selected for this project is its low carbon footprint. Transporting the CLT and LVL elements from Austria to Australia generated just over 200 tonnes of CO₂ — less than the emissions associated with overland transport to a nearby city such as Paris. This is because sea freight is more efficient and timber is a comparatively lightweight building material.

By importing CLT from a country like Austria, where the technology and expertise are well established, Australia gains access to advanced manufacturing techniques and high-quality materials that are not yet widely available domestically.

The project targets the highest environmental benchmarks, including Platinum LEED and Platinum WELL certifications, 6-Star Green Star, 5.5-Star NABERS Energy, and 4-Star NABERS Water ratings.
