Powerhouse Parramatta will soon be completed in Sydney
With architecture from Moreau Kusunoki with Genton, Powerhouse Parramatta takes shape in Western Sydney, Australia. The ambitious project, which is expected to be completed by the end of 2026, will bring a colossal museum in Parramatta, a part of the city that is growing rapidly but has had fewer institutions of this scale.
What stands out first is how the building handles its size. Two main volumes sit side by side, each wrapped in a deep structural skin. Instead of relying on an apartment facadethe architects push the structure outwards, turning it into something that can be read immediately from the street. It gives the building a presence without relying on height alone.

Edit the structure on the facade
This outer layer of Powerhouse Parramatta’s facade does a lot of work. It is a steel exoskeleton made of repeating diagonal members, forming a dense load-bearing mesh while sitting off the main envelope. It can be understood as a structure first, but it also acts as a sun control, especially in Sydney light where westerly exposure can be strong.
Up close, the system feels almost over-resolved in a good way. Every node, every link is readable. It has that quality that one can imagine how it was made and put together, piece by piece. Seeing the maintenance crews moving along it gives a sense of scale and thickness that drawings never quite capture.

Interior space and light
Inside, the reward is volume. The arcades are large and open, with minimal interruptions. The structure sits outside the glass line so the interior remains clean while still lending depth and rhythm to the facade. Light passes through the grid and lands on the floors in a way that changes throughout the day.
The floors themselves are kept simple, mostly polished concrete, which helps reflect that light and keep the focus on the displays. Visitors have large attractions in the spaces and the proportions feel tuned for large installations without making smaller works feel lost.
Traffic is fairly relaxed as there is no single path that visitors are forced to follow, which makes sense given the range of programs inside. Go up and across through a series of large connections, with views towards the city and back through the building. It seems that the architects were trying to give the curators room to adapt collections and exhibitions over time.

What shifts it beyond a typical museum is how much is packed into it. Adjacent to the galleries, there are studios for artists and researchers, learning spaces connected to the Lang Walker Family Academy, and a full kitchen for public programs around food. It begins to feel closer to a working campus than a single-use building.
At ground level, the project opens onto a landscaped public space connected to the river. It is designed to remain accessible throughout the day, which is important in this part of Sydney where public space carries a lot of social weight. The building steps back enough to allow this space to breathe.
From an environmental point of view, the project aims high. It is designed to operate with net zero emissions from day one, with water and energy harvesting systems integrated into the overall strategy. The exoskeleton plays a role here too, reducing heat build-up before it reaches the glass.
