Powerhouse Castle Hill / Lahznimmo Architects

Powerhouse Castle Hill is a storehouse for the Powerhouse Collection, supporting research and conservation. It forms part of the Museum Discovery Centre, operated in partnership with the Australian Museum and the Museums of History New South Wales. The site housed six large storage sheds for the collection that were reaching capacity. About 95% of the Powerhouse Collection is maintained in storage at any time, most of it at Castle Hill. In advance of the construction of Powerhouse Parramatta, more items were to be moved to Castle Hill, along with staff and ancillary functions such as conservation laboratories.
