The expansion of the Museums Discovery Centre has been approved by the NSW Government and will move into delivery phase.

The expansion will significantly increase community access through new public spaces.

The new state-of-the-art building designed by NSW based architects Lahznimmo will include new facilities for the storage, care, research and viewing of the Powerhouse Collection, as well as flexible spaces for education and public programs, workshops, talks and events.


Project Site
The Museums Discovery Centre is located at 172 Showground Road Castle Hill. As part of the proposed expansion, a new building will be constructed on a part of the adjacent TAFE site along the eastern boundary of the existing Museums Discovery Centre site. The land will be transferred to Powerhouse from TAFE NSW.

Project Status
The Powerhouse Museum and Create NSW submitted a Planning Proposal to enable the expansion of the Museums Discovery Centre at Castle Hill. This Planning Proposal sought amendments to site zoning and building height limits to facilitate the construction of a new building. It was publicly exhibited by The Hills Shire Council from 19 June to 17 July 2020. The Planning Proposal has now been approved.

Concurrently, an Environmental Impact Statement (EIS) was developed as part of the State Significant Development Application for the expansion of the Museums Discovery Centre. The Environmental Impact Statement was on public exhibition from 4 November to 1 December 2020. The Department of Planning, Industry and Environment is currently collating all submissions that were made during this period. A full copy of the EIS and all other technical documents can be found at this link.
