Load Bearing Wall Removal Cost in Perth (2026)
In Perth removing a load-bearing wall is priced by the span opened, the load above, and the beam, with double-brick walls making the job heavier.

Removing a load-bearing wall always needs an engineer to size the beam and usually a permit, this is not a DIY or cash-job decision. Getting it wrong is a structural and safety failure.
Taking out a load-bearing wall is a common way to create open-plan living, but the beam that replaces the wall (often steel) and the engineering are the real costs. Always confirm whether a wall is load-bearing before planning.
Ways to save
- Confirm whether the wall is actually load-bearing first, removing a non-load-bearing wall is far cheaper.
- Get the engineering done early, the beam size drives the whole cost.
- Bundle the make-good (ceiling, cornice, flooring) into the quote so there are no surprises after the beam goes in.
How we estimate this
Removing a load-bearing wall in Australia typically costs around $4,500 to $10,000 in 2026 for a single-storey wall, rising to $12,000 to $25,000 for a wide opening or one supporting a second storey. Engineering, permits and making good add to that.

What a load bearing wall removal costs in Perth
Removing a load-bearing wall in Perth is priced on the width of the opening, the weight carried above, and the beam that replaces the wall, since a structural wall supports the floor or roof above and cannot simply be demolished. The span and the load set the beam, so a wide opening needs a heavier beam and more propping, and the beam, the propping and the making good drive the cost.
Perth's common double-brick construction makes the job heavier, because a load-bearing wall in a double-brick home is two solid leaves of brick carrying the roof or upper floor, so cutting it out and propping the masonry is more involved than removing a timber-framed wall, and the beam must carry a heavier masonry load into solid brick piers. A structural engineer designs the beam and the bearings, props hold the masonry while it comes out, and the opening is made good. The sandy, stable soils give good footings for a new support post. The dry climate is no factor for the structure. The isolation of the WA market rarely affects a standard steel beam, and labour sits near the national average, with identifying the load-bearing wall the first step.
Removing a load-bearing wall is structural building work that needs a licensed builder and a structural engineer to design the beam, with building approval, in Western Australia under WA Building Services. For a Perth home, the clearest way to price load-bearing wall removal is by the span, the load above, and the engineer-sized beam, with the double-brick masonry making it a heavier job.

Frequently asked questions
How is load-bearing wall removal priced in Perth?
By the width of the opening, the weight carried above, and the engineer-sized beam that replaces the wall, so a wide opening needs a heavier beam and more propping, and the double-brick masonry makes a Perth job heavier than a timber-framed one.
Does double-brick make wall removal harder in Perth?
Yes. A load-bearing wall in a Perth double-brick home is two solid leaves of brick carrying the roof or upper floor, so cutting it out and propping the masonry is more involved than a timber wall, and the beam carries a heavier load into brick piers.
Why does a load-bearing wall need a beam in Perth?
Because it supports the floor or roof above and cannot be demolished alone, so a structural engineer sizes a beam and its bearings to carry that masonry load, with props holding the brick while the wall comes out in a Perth home.
Do I need a licence to remove a load-bearing wall in Perth?
Yes. It is structural building work needing a licensed builder and a structural engineer to design the beam, with building approval, in Western Australia under WA Building Services.
