Tumbalong Green Stage

Designed by Hassell in collaboration with TTW and delivered by Kane Construction, the Tumbalong Green Stage hosts live concerts, performances, festivals, exhibitions and community events.

Situated on the edge of Sydney’s CBD, the striking diagrid timber shell features an anchored system at just three points to create a light, open feeling. The diagrid shell comprises 314 unique glue-laminated (GLT) beams made from sustainable European spruce and 1,298 bespoke steel plates all and delivered in record time. The stunning GLT shell is clad in a modern, high-tech PVC fabric and framed by a sleek steel ring beam.

Theca Timber played a key role in transforming the ambitious design into a manufacturable, transportable, and easily assembled structure. The complexity was immense—every single GLT element is uniquely shaped with varying dimensions, angles and connections, supported by 1,298 bespoke steel plates. Adding to the challenge, Theca Timber, through its specialist consultant team of timber professionals, delivered the entire structure within just four months of final design approval.

Completed in time for the 2023 FIFA Women’s World Cup, the stage welcomed hundreds of passionate football fans who gathered beneath its canopy to watch the action unfold on massive screens.

“The sound shell at Tumbalong Park is Sydney’s first major purpose-built, live outdoor cultural venue in the heart of the city. It is destined to become an iconic landmark rivalling sites such as the Sidney Myer Music Bowl or Federation Square in Melbourne or the HOTA Outdoor Area at the Gold Coast.”
