Construction has officially wrapped on the $915 million Powerhouse Parramatta, marking a major milestone for Western Sydney and one of the most significant cultural infrastructure projects in Australia.

The 30,000-square-metre museum has now been handed over to the Powerhouse team by builder Lendlease, transitioning the project from construction into exhibition fit-out and final activation works ahead of its anticipated opening later in 2026.

The landmark development forms part of the broader $1.3 billion Powerhouse renewal program and is being recognised as the largest cultural infrastructure investment in NSW since the Sydney Opera House.

Once open, the museum will feature seven expansive exhibition zones, including a dramatic 18-metre-high gallery space designed for large-scale installations such as the Task Eternal space exhibition. Additional features include a rooftop garden, learning and demonstration spaces, and accommodation for visiting students and researchers.

Officials say the museum is expected to attract up to two million visitors annually, positioning it as a major cultural and tourism driver for Parramatta and the wider Western Sydney region. The project has also delivered significant economic impact during construction, with thousands of workers involved and a strong proportion of contracts awarded to Western Sydney businesses.

Final exhibition installation works are now underway, with an opening expected later in 2026.
