Lahznimmo Architects has designed Powerhouse in Castle Hill, Australia.

In 2018, CreateNSW engaged Lahznimmo Architects to design a new 9,000-square-metre facility for Powerhouse Castle Hill.

The facilities serve the needs of various groups, including staff, volunteers, education groups, researchers, artists, scientists, industry partners and the general public.

In addition to increasing storage space, the architects expanded the site's ability to hold public exhibitions, providing a much-needed museum facility for the people of Sydney's northwest.

The building is minimal and elemental, described as "Beautiful Utility" with its raw expression of materials – including mill–finished aluminium and off-form concrete – showcasing their natural properties.

This project has been longlisted in the cultural project category of Dezeen Awards 2024.
