A landmark development transforming Sydney's skyline

Multiplex has transformed Quay Quarter Tower (QQT) from an existing 45-year-old 45,000 square metre office building into an 89,000 square metre world-class, highly sustainable commercial tower.

The 50-storey commercial building is a landmark site at Circular Quay and is a vibrant destination supporting workers, residents and visitors in Sydney. 

The revitalised tower pierces the skyline with a striking design, comprising a series of shifting, cantilevered glass volumes stacked upon each other. This unique design provides an atrium that cuts through the core of the building, offering expansive views of Sydney Harbour. 

In a world-first, Multiplex demolished and reconstructed one side of the tower, whilst simultaneously retaining and refurbishing the other side. This adaptive reuse retained 68% of the building’s core and enabled significant environmental and operational efficiencies.
