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 Adelaide
Removing a load-bearing wall in Adelaide is costed by the width of the opening, the load above, and the beam that carries that load once the wall is gone, because a structural wall holds up the floor or roof and cannot be knocked out alone. The span and the load set the beam, so a wide opening under a second storey and roof needs a heavier beam and more propping than a short single-storey opening. The affordable labour that marks the city out keeps this labour-heavy structural job the cheapest of any mainland capital.
Adelaide's older stone cottages and villas often have solid stone or double-brick load-bearing internal walls, so opening one up to create open-plan living means cutting masonry and carrying a heavy load on a new beam into stone or brick bearings, which is careful work. A structural engineer designs the beam, props hold the masonry while the wall comes out, and the opening and any period cornices are made good. Reactive clay can mean checking the footing under a new post. The cheap local labour makes the beam, propping and making good more affordable than in the dearer capitals, and telling a load-bearing wall from a non-structural one, which is far cheaper to remove, is the essential 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 development approval, in South Australia under Consumer and Business Services. For an Adelaide home, the clearest way to price load-bearing wall removal is by the span, the load above, and the engineer-sized beam, with cheap labour easing the labour-heavy job.

Frequently asked questions
Is load-bearing wall removal cheap in Adelaide?
Comparatively, yes. The affordable labour that marks the city out keeps this labour-heavy structural job the cheapest of any mainland capital, so the beam, propping and making good are more affordable in Adelaide than in the dearer capitals.
How is load-bearing wall removal priced in Adelaide?
