Powerhouse Parramatta soon to complete in sydney
With architecture by lead designer Moreau Kusunoki and local architect Genton, Powerhouse Parramatta is taking shape in Western Sydney, Australia. The enthusiastic project, which is anticipated to complete in late 2026, will bring a gigantic museum to Parramatta, a part of the city that has been growing quick but has had less institutions of this scale.
What sticks 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 counting on a flat exterior, the architects press the structure outside, turning it into something that can be checked out instantly from the street. It gives the building an existence without leaning on height alone.

It is a steel exoskeleton made from repeating diagonal members, forming a dense lattice that carries loads while sitting off the main envelope. It can be comprehended as structure first, but it also performs as sun control, especially in the Sydney light where the western exposure can be intense.
Up close, the system feels practically over-resolved in a great way. Each node, each connection is clear. It has that quality where one can envision how it was produced and put together, piece by piece. Seeing upkeep crews moving across it offers it a sense of scale and thickness that illustrations never ever quite capture.

The galleries are big and open, with really few interruptions. The structure sits outside the glass line, so the interior stays clean while still borrowing the depth and rhythm of the exterior. Light filters through the lattice and lands across the floors in a manner that changes throughout the day.
The floors themselves are kept basic, mostly polished concrete, which assists show that light and keeps the concentrate on the exhibitions. Visitors get long sightlines throughout the spaces, and the proportions feel tuned for huge installations without making smaller works feel lost.
Flow is relatively loose as there is no single path that visitors are required to follow, which makes sense given the series of programs inside. You move up and throughout through a series of big connections, with views out to the city and back through the building. It feels like the architects were attempting to give managers space to adjust collections and exhibitoons in time.

Alongside the galleries, there are studios for artists and scientists, finding out areas tied to the Lang Walker Family Academy, and a complete cooking area setup for public programs around food. It starts to feel closer to a working campus than a single-use building.
At ground level, the job opens out to a landscaped public location that connects to the river. It is designed to remain accessible all day, which is very important in this part of Sydney where public space brings a lot of social weight. The structure steps back enough to enable that space to breathe.
From an environmental viewpoint, the job is aiming high. It is developed to run at net-zero emissions from the first day, with systems for water collection and energy constructed into the overall method. The exoskeleton plays a part here too, lowering heat gain before it reaches the glass.
