Lahznimmo Architects has completed the Powerhouse Castle Hill in northwest Sydney, an imposing shed-like storage facility wrapped in corrugated aluminium and concrete.

Owned and operated by the Powerhouse Museum group, the 9000sqm facility is intended as a public-facing storehouse containing a mix of storage, exhibition and conservation facilities, alongside spaces for research and community engagement.

The expansion of the Museums Discovery Centre, Powerhouse Castle Hill was delivered to better protect State heritage and cultural assets.

The new building also provides more space for education, research and public programs. It will enhance the conservation, preservation and exhibition of collections for generations to come.
