The expansion to the Castle Hill home of the world-renowned Powerhouse Collection is moving forward at pace with main works underway and construction to be completed in a year.

The Museums Discovery Centre expansion 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 thousand objects from the Collection.

Taylor Construction Group has commenced work on the expansion which will increase the Powerhouse Museum’s storage space by 30 per cent and is scheduled to be completed by the end of 2022.

The new state-of-the-art building designed by NSW based architects Lahznimmo includes 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.

The expansion will dramatically increase community access as a public facing cultural destination for the people of the Hills Shire and the broader public of NSW.


Museum Trust President, Peter Collins AM QC said:

“Castle Hill is the beating heart of the Powerhouse Collection – and it’s a place that too few people have seen. This expansion project is going to change that bringing unprecedented access to this incredible Collection to the public – especially the communities of the Hills Shire,” Mr Collins said.

“It is only when you walk through the storage facilities at Castle Hill that you truly understand the scale and breadth of the encyclopaedic Powerhouse Collection – the number of collection disciplines on display at this site is just remarkable.”


Powerhouse Chief Executive Lisa Havilah said:

“With this expansion we are delivering a world-class space for our conservators, collections teams, workshop staff and others to care for the Collection in an environment that is fit to house the thousands of wonderful objects that are owned by the people of NSW,” said Ms Havilah.

“What is fantastic about this project is that it will deliver a platform for exhibitions and programs that never existed in Castle Hill before. We will be able to showcase the Powerhouse Collection like never before to the local community so I’m incredibly excited for the people of Castle Hill and the Hills Shire district.
