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 30,000 square metres of space and more than 18,000 square metres dedicated to exhibition and public areas across seven storeys, this is far more than a relocation—it’s a recalibration of where culture lives in Sydney.

Powerhouse Parramatta Completion Date

The project is officially on track to open in late 2026, with construction—led by delivery partner Lendlease—now reaching a major milestone. The main building is complete, with interior exhibition fit-outs underway and final works continuing across the public domain.

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 expands that vision. As the first major cultural institution permanently based in Western Sydney, it’s designed as a dynamic, evolving museum model—one that brings together industry, community and collection in new ways.

Expect immersive, large-scale exhibitions and live programming, including opening showcase Task Eternal, which explores humanity’s enduring quest to defy gravity, take flight and journey into space. Five major international exhibitions are currently in development, with the full opening program to be revealed later this year.

Powerhouse Parramatta Architects

The design, led by Moreau Kusunoki (Lead Designer) alongside Australian firm Genton (Local Architect), was selected following an international competition launched in 2019. Once open, it’s expected to welcome millions of visitors annually, cementing its place as a global cultural destination for Western Sydney.

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.

More than 50 Australian designers have been commissioned to shape the experience of the museum itself. Multidisciplinary Australian firm Tyrrell Studio has shaped the exterior, connecting public domain to the surrounding landscape in an exploration of the neighbouring river through weaving stones, pools of rainwater and vegetation. 

There are also overnight accomodation spaces, designed by architecture and interior design studio YSG, and an onsite restaurant by George Livissianis (of Olympus Dining)—led by a pallet of aluminium, leather and cork.

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.

Key Features Of Powerhouse Parramatta

The Lang Walker Family Academy will deliver world-class immersive STEM education programs, including overnight residencies for up to 10,000 secondary students each year—positioning 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 is a 200-seat demonstration theatre designed to bring together chefs and producers, embedding the science and culture of food into the museum’s programming.

Monumental Exhibition Spaces

Powerhouse Parramatta will feature one of the largest column-free exhibition spaces in Australia, spanning more than 2,000 square metres with an 18-metre ceiling—allowing for ambitious, large-scale installations rarely seen locally.

Rooftop Terrace & Observatory

A rooftop terrace will offer sweeping views across Parramatta to the Sydney CBD, alongside a productive garden with Indigenous plant species, a greenhouse, and an observatory with telescopes beneath a retractable roof. The ING Pavilion will host talks, workshops and public programs.

Residencies & Collaboration

The museum will house 30 residential studios, bringing together artists, scientists and researchers from around the world to collaborate on-site.

Sustainability & Design

Powerhouse Parramatta will open with net-zero emissions from day one and is the first public building in Australia—and the first project in Western Sydney—to achieve a 6 Star Designed rating under the Green Building Council of Australia’s Green Star Buildings framework.

Sustainability is embedded across every layer of the project, from water harvesting and renewable energy to zero-waste exhibition practices and Caring for Country principles developed in collaboration with First Nations communities.

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.

 

Powerhouse Parramatta Parking

While there's no on-site parking available at the Powerhouse, there are various 24-hour parking stations across Parramatta CBD—and within a walkable distance of the venue. 

If you'd prefer not to try your luck, you can easily jump on the metro or lightrail from Sydney CBD.

The museum forms part of a broader river foreshore precinct and represents a transformative investment in Western Sydney—one of Australia’s fastest-growing and most diverse regions.

Beyond exhibitions, it’s expected to drive tourism, support jobs and expand access to arts and culture across the region. More broadly, it signals a structural shift: world-class cultural infrastructure embedded in the heart of Western Sydney.
