Powerhouse Parramatta: Inside Western Sydney’s $1B Museum Set To Transform The Cultural Landscape

Located on Dharug land, Powerhouse Parramatta is shaping up to be one of the most significant new museum projects anywhere in the world—and the largest investment in cultural infrastructure in NSW since the Sydney Opera House.

Set to open in late 2026, the new museum will become the first NSW State Cultural Institution based in Western Sydney, anchoring a major new cultural precinct along the Parramatta River. With more than 18,000 square metres of exhibition and public space across seven storeys, and projections of two million visitors annually, this is far more than a relocation—it’s a recalibration of where culture lives in Sydney.

When Will Powerhouse Parramatta Open?

The design for Powerhouse Parramatta was selected following an international competition launched by Create NSW in January 2019. Construction has since progressed through one of the largest and most architecturally complex cultural infrastructure builds currently underway in Australia.

The project is expected open its doors in late 2026. Once operational, it will become the largest museum in NSW—welcoming locals, interstate visitors and international audiences alike.

What Is Powerhouse Parramatta?

Powerhouse is already the largest museum group in Australia, sitting at the intersection of arts, design, science and technology. Custodian to more than half a million objects of national and international significance, its collection offers a deep insight into stories of innovation and achievement across the applied arts and sciences.

Powerhouse Parramatta will bring that collection into one of Australia’s fastest-growing and most diverse communities.

As the first major cultural institution to be permanently based in Western Sydney, the museum is designed to create a dynamic program where community, industry and collection intersect—redefining what a contemporary museum can be.

Expect immersive exhibitions, large-scale installations, live programming and hands-on engagement that demonstrates the continued impact of design, engineering, technology and scientific thinking on our everyday lives.

Key Features Of Powerhouse Parramatta

The Lang Walker Family Academy will deliver world-class immersive STEM education programs, industry engagement and even overnight stays within the museum. Designed as a dedicated play-and-learning space for science, technology, engineering, arts and mathematics (STEAM), it positions the museum as an active learning hub—not just an exhibition space.

Vitocco Kitchen: A 200-Seat Culinary Theatre

Food will also take centre stage. The Vitocco Kitchen features a 200-seat demonstration theatre designed to bring together Australian and international chefs and producers. It’s a bold integration of culinary arts into a museum setting—blurring the line between exhibition, performance and shared experience.

Holdmark Gallery: Monumental Exhibition Space

The Holdmark Gallery will offer 2,300 square metres of floor space with soaring eight-metre-high ceilings, allowing for large-scale installations and ambitious exhibitions rarely seen in Australia. This scale positions Parramatta as a serious global exhibition destination.

Event Spaces & 24-Hour Activation

Beyond exhibitions, Powerhouse Parramatta will include event and function spaces, generating revenue that is reinvested directly into programming and the collection. The broader precinct is designed to operate as a seven-day, 24-hour tourist drawcard—stimulating cafés, bars and retail in the surrounding area.

The Exoskeleton Design & Sustainability Credentials

Designed by Moreau Kusunoki (Lead Design Architect) and Genton (Local Design Architect), the building’s striking steel exoskeleton is one of its defining features. Rather than concealing its structure, the museum celebrates it—the machine-like superstructure articulating the façade and shaping the building’s identity.

Powerhouse Parramatta is also targeting a 6 Star Green Star Buildings rating—the first public building in Australia to aim for this benchmark. Sustainability measures include climate-ready design, high-performance building systems and integrated landscape connections to the Parramatta River foreshore.

How Will Powerhouse Parramatta Impact Western Sydney’s Economy?

The museum forms part of the broader River Foreshore precinct, developed through collaboration between the City of Parramatta Council and the NSW Government. Alongside a redeveloped Riverside Theatres, the area is set to become a major arts, culture and innovation hub.

Economic modelling suggests the precinct could contribute between $106 million and $422 million to the local economy by 2028—supporting jobs, tourism and long-term growth in Western Sydney.

More importantly, it signals a structural shift: world-class cultural infrastructure embedded in one of Australia’s most diverse and rapidly expanding communities.
