The Powerhouse at Castle Hill achieved a major construction milestone with the pouring of concrete foundations as part of its $30 million renewal project.

A span of 640sqm concrete, the equivalent of 88 trucks, was poured over two days to create two suspended slabs, marking the first step in the formation of public spaces for the museum.

Due to be completed in early 2023, the Powerhouse Castle Hill expansion includes “a new public-facing building, expanding storage space by 30 per cent, and a new level of access to the Powerhouse collection for the communities of the Hills Shire and Greater Sydney” according to Powerhouse Chief Executive Lisa Havilah.

The new building will also feature state-of-the-art conservation facilities and flexible spaces for learning, research and exhibition.

“Increasing community access to the Powerhouse collection lies at the heart of this expansion,” Ms Havilah said.

“Upon completion, Powerhouse Castle Hill will house more than 500,000 objects from the Powerhouse collection. With dedicated exhibition spaces, additional storage, production, conservation and operational facilities, Powerhouse Castle Hill will be a remarkable cultural asset for the local Castle Hill community and beyond.”

The expansion of Powerhouse Castle Hill forms an integral part of the Powerhouse renewal program which includes the construction of the new flagship museum Powerhouse Parramatta, the renewal of Powerhouse Ultimo and the digitisation of more than 330,000 thousand objects from the collection.

It is designed by NSW-based architecture firm Lahznimmo Architects and constructed by Taylor Construction Group. The new building is designed with an appreciation of concrete as more than just a building material; it will be a core design feature of the new facility.

The site remains open to the public every weekend throughout the duration of the build. For more information, go to
