The biggest piece of Royal Perth Hospital's $807.3 million emergency department expansion has cleared its planning hurdle, with the Western Australian Planning Commission approving the next stage of the CBD redevelopment on Wednesday. The decision was first reported by WAtoday and Business News on Wednesday afternoon.

The approval covers the new S Block at 212 Wellington Street — a purpose-built tower on the north-western edge of the Royal Perth campus, together with a three-level link structure joining it to the existing R Block, new vehicle access and landscaping. The Department of Housing and Works, which lodged the application on the hospital's behalf, put the value of that component alone at $485 million.

It is the planning decision the rest of the project has been waiting on. Foundation and piling works started at the site in late June, but they were the preliminary stage: the building that will actually house the new emergency department needed the Commission's sign-off before it could rise.

What is being built

Two full floors of the new block are set aside for the emergency department, with the remaining levels adding inpatient capacity to a hospital that has spent years running at the edge of its space. The government's own description of the project promises expanded acute care and fast-track areas, more ambulance bays, and better patient flow through the department — the unglamorous plumbing of an ED, and the part that determines whether people sit in a corridor.

The new block sits roughly 500 metres from the current emergency department, which is deliberate. The existing ED stays open and fully operational for the entire build, with construction zones walled off from clinical areas. Nobody has to move out while it goes up.

The work is being delivered by Lendlease under an alliance arrangement known as the Perth Pulse Alliance, managed by the Office of Major Infrastructure Delivery on behalf of the Department of Health and the East Metropolitan Health Service. Construction is scheduled to finish in 2028.

One detail worth watching

There is a gap in the public record that has not yet been explained. When the project was announced in November 2025 — with $33 million for detailed planning — the government described a six-storey building. The development application advertised for public comment in July 2026 describes a nine-storey emergency department block. The state's own Building for Tomorrow project page still says six.

Three extra floors on a CBD hospital tower is not a rounding error, and it is the kind of change that usually reflects either a redesign or a decision to build in capacity the original brief left out. Everything Perth has not been able to confirm which. The approved plans will settle it.

How the decision was made

The application was assessed under Part 10 of the Metropolitan Region Scheme, the pathway used for public works on state land, which puts the decision with the Planning Commission rather than the City of Perth. It was advertised for public comment through the Department of Planning, Lands and Heritage from 3 July to 17 July 2026 — a two-week window for a half-billion-dollar building.

That is standard for this pathway, and it is also why a project of this size can move from public advertisement to approval without the drawn-out council fight a private tower of the same scale would attract.

Why it matters

Royal Perth is the trauma centre for the eastern half of the metropolitan area and the hospital that receives the CBD's worst nights. Its emergency department has been a fixture of WA's ambulance ramping and bed-block arguments for the better part of a decade, and no amount of process reform has changed the fact that the physical department is too small for the volume walking and being wheeled through it.

The expansion is funded from the Cook Government's $2 billion Building Hospitals Fund. At the start of construction in June, Premier Roger Cook said the project was "part of our record investment in hospitals", while Health Minister Meredith Hammat framed it as delivering "more beds, more capacity, and improved patient flow".

Those are the claims the 2028 opening will be measured against. For now, the practical effect of Wednesday's decision is narrower and more concrete: the cranes can go up, and Wellington Street gets a construction site for the next two years.

What happens next

With planning approval in hand, the main build proceeds on the S Block site while the current emergency department keeps taking patients. A detailed masterplan for the wider Royal Perth campus was flagged for later in 2026. The department itself is not due to open its doors until 2028.
