Cost to Remove Load Bearing Wall: What to Expect
The cost to remove a load bearing wall in an Irish home typically ranges from €2,000 to €6,000, depending on the size of the wall, the steel beam required and the finishing work involved.
Knocking through a load bearing wall is one of the most popular ways to create open-plan living space, but because the wall supports the structure above it, the job needs careful planning, a structural engineer and an experienced demolition team.
In this guide, the team at Cork Demolitions breaks down every cost involved so you know exactly what to expect before work begins.
What Affects the Cost to Remove Load Bearing Wall?
Every home is different, but these are the main factors that shape your final price:
- Size of the opening. A single doorway-sized opening costs far less than knocking through an entire wall between a kitchen and living room. The wider the span, the larger (and more expensive) the steel beam needed to carry the load.
- Steel beam (RSJ) supply and installation. A structural engineer must size a rolled steel joist for your specific span. Expect to pay roughly €400–€500 per metre for the beam, plus installation.
- Structural engineer fees. Before any wall removal begins, an engineer confirms the wall is load bearing, calculates the beam size and provides certification. Fees in Ireland are usually €400–€700.
- Making good and plastering. Once you remove the wall, you need to patch and plaster the floor, ceiling and adjoining walls. Budget €500–€1,000 for a seamless finish.
- Waste removal. Knocking down a wall creates a surprising amount of rubble. Waste disposal typically adds €200–€400 unless your quote includes it.

Why You Need a Structural Engineer
A load bearing wall holds up the floors or roof above it. Removing one without proper temporary propping and a correctly sized beam can cause serious structural damage. A structural engineer will confirm whether the wall is structural, specify the steel beam and issue certification once the work is complete. That certificate matters for your home insurance and for any future sale of the property.
Building Regulations in Ireland
Removing a load bearing wall must comply with Irish building regulations because the work affects the structural stability of your home. You do not normally need planning permission for internal alterations, but a qualified engineer should certify the finished job. A professional contractor will make sure to fire-protect the beam with plasterboard and complete everything to regulatory standards.
How to Save Money on Wall Removal
- Get at least three quotes from local contractors.
- Keep the opening smaller where possible — a shorter span means a smaller beam.
- Combine the wall removal with a larger renovation to share labour and setup costs.
- Do the painting and decorating yourself once the plastering is done.
Frequently Asked Questions
How long does it take to remove a load bearing wall?
Most jobs take two to three days: propping, beam installation and demolition first, then plastering and finishing.
Can I remove part of a load bearing wall without a beam?
No. Even a partial opening in a structural wall needs proper support. Always consult a structural engineer first.
Is removing a load bearing wall worth it?
Yes — an open-plan living space adds light, improves flow and consistently increases property value with Irish buyers.
