Key features
The revised concept design scheme for the Powerhouse Ultimo Revitalisation was developed by architects Durbach Block Jaggers partnering with Architectus, Tyrrell Studio and Youssofzay + Hart.
The design concept for the revitalisation of the Powerhouse Ultimo responds to community feedback. It includes:
- Four flexible, international-standard exhibition spaces designed for large-scale, high-quality applied arts and sciences exhibitions.
- Conservation of the heritage-listed original Power Station buildings for their ongoing reuse by the Powerhouse.
- A 2,000 sqm Museum Entry Terrace, linking the museum to The Goods Line and Macarthur Street, designed for civic use, museum programming and events.
- Seamless visitor access with a new circulation system connecting exhibitions, learning spaces, and programs.
- Separating front-of-house and back-of-house operations from exhibition and circulation spaces.
- A newly activated façade along Harris Street, which will improve the museum's contribution to the Ultimo streetscape.
- Dedicated spaces designed for the Powerhouse learning programs, enabling the museum to create immersive educational experiences, workshops and programs catered to students and learners of all ages.
The Department of Planning, Housing and Infrastructure (DPHI) finalised the State Significant Development Application (SSDA) on 24 March 2025.
Following SSDA determination in March 2025, Richard Crookes Constructions has been appointed to deliver the revitalisation.
All planning documentation is available to view on the Planning Portal.
Site location
The project is located within the site of the existing Powerhouse Ultimo at 500 Harris Street, Ultimo. This 1.7-hectare site has been home to the museum since 1988.
The State Significant Development Application includes the Ultimo Power Station, Wran building, the former Post Office, Boiler House and Turbine Hall.
Adjacent to the site is the Harwood building, which is not included in this development. It remains in the ownership of the museum and will continue to be used for museum operational purposes.
