Load Bearing Wall Removal Cost Calculator
Estimate the cost of removing a load-bearing wall to open up a space. The wall itself is cheap to remove, the cost is the structural beam that replaces it, the engineering, and making good the ceiling and floor.
Your load bearing wall removal details
Your estimate sits within the typical range.
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.
