Designed by 3XN and developed in collaboration with BVN, the Quay Quarter Tower in Sydney, Australia, is the first model of an adaptive reuse project for a skyscraper, showcasing the potential of redesigning existing buildings to reduce the environmental impact of construction and demolition.

The 206-meter-high building repurposed the 1976 AMP Center, preserving almost all its original structural elements, such as beams, columns, and panels, as well as 95% of its original core. This approach, along with other sustainable interventions like a self-shading facade and a removable flooring system, resulted in a savings of 12,000 metric tons of carbon dioxide. During the international conference of the Council on Tall Buildings and Urban Habitat (CTBUH) held in Singapore and Kuala Lumpur, the Quay Quarter Tower was awarded the Best Skyscraper Worldwide for 2023.

The building aims for sustainability in all aspects of its design, with a strong focus on community and connectivity. It functions as a vertical village to promote interaction among its inhabitants and serves as a cherished urban destination due to the green spaces it provides. The internal commercial area extends onto terraces, and the rooftop houses a public park.
