Powerhouse Parramatta has officially reached a major construction milestone, as the monumental structure hits its full 75-metre height and the completion of its distinctive steel exoskeleton is announced. This marks a defining moment in the development of the largest museum in New South Wales history—and the first major cultural institution to be built in Western Sydney.
Spearheaded by the Minns Labor Government, the Powerhouse Parramatta represents the state’s most significant investment in cultural infrastructure since the opening of the Sydney Opera House in 1973.
A hallmark of the museum’s architectural design is its striking steel exoskeleton, comprising the majority of the 12,000 tonnes of steel used throughout the build. The innovative design enables all seven of the museum’s exhibition spaces to be completely column-free. Two of these expansive, open-plan areas have already been handed over to the Powerhouse Museum team to begin the exhibition fit-out phase.
Expected to draw in over 2 million visitors annually, Powerhouse Parramatta is set to become a world-class cultural anchor for Sydney’s west—driving not only cultural enrichment but also significant economic activity in the region.
Premier Chris Minns described the project as “a once-in-a-generation investment in Western Sydney’s cultural lifeblood.”
“Now that the building has reached its full height of 75-metres, you can truly see the scale and ambition of this project – staking its place proudly in the Parramatta skyline.”
The Premier reiterated his government’s commitment to redressing the historic underinvestment in Western Sydney, adding,
“From schools and hospitals to the Parramatta Powerhouse, we’re getting on with the job of delivering this new infrastructure.”
The construction project has so far engaged a workforce of more than 2,500 people, with over 1.45 million hours worked on site. In addition, more than $150 million in contracts have been awarded to businesses in Western Sydney, reflecting the project’s significant economic impact.
Arts Minister John Graham highlighted the museum’s role in positioning Western Sydney at the forefront of Australia’s cultural landscape.
“This site will celebrate and showcase the best of applied arts and sciences. It will ensure that Western Sydney is not just part of the cultural conversation, but leading it.”
The project has also attracted substantial philanthropic support, with the Neilson Foundation announcing a generous $5 million donation, securing naming and presentation rights for Exhibition Space 5. This brings the total raised through the Powerhouse Museum’s philanthropic campaign to $65.9 million, supplementing the $840 million investment by the NSW Government across the Powerhouse Parramatta and Castle Hill sites.
The Neilson Foundation’s contribution will fund the development of The Dark—an immersive and interactive exhibition for children. Created by award-winning Australian designers Kip Williams and Elizabeth Gadsby, the experience will be developed in collaboration with early learning experts and creative partners.
Kerr Neilson, Chair of the Neilson Foundation, said:
“We are proud to support Powerhouse Parramatta as exhibition partner for this immersive and innovative cultural experience for young audiences. This reflects our shared commitment to fostering curiosity and learning in the next generation.”
Minister for Lands and Property Steve Kamper celebrated the topping-out milestone:
“Once finished, Powerhouse Parramatta will be the largest museum in NSW, with 18,000 square metres of exhibition and public space — a true cultural and architectural icon for Parramatta and Western Sydney.”
Local Member for Parramatta Donna Davis added:
“We’ve been gradually watching the Powerhouse Museum reach new heights and today we celebrate that it’s one step closer to completion.”
As construction progresses toward finalisation by the end of this year, the site will then be handed over to the Powerhouse team for full exhibition fit-out, ahead of a public opening in late 2026.
Managing Director for Lendlease, Stephanie Graham, remarked:
“Our progress on this new cultural landmark for Western Sydney reflects our design and construction expertise, underpinned by strong partnerships with our customers and supply chain.”
From its visionary design and scale to its community impact and cultural significance, Powerhouse Parramatta is shaping up to be much more than a museum—it is a transformative force for Sydney’s west, celebrating innovation, inclusion, and imagination.
