How to Remove a Load-Bearing Wall
Removing a load-bearing wall is one of the most common ways to open up a London home — but it must be done in the right order. Do not start demolition before the design is agreed.
Step 1: Confirm the Wall Is Load-Bearing
Signs a wall is load-bearing:
- Floor or ceiling joists rest on top of it
- Another wall sits directly above it
- It runs perpendicular to the joists
- It is part of the original structure near the middle of the house
- It is masonry (brick or block) rather than thin plasterboard
A structural engineer can confirm this from a site visit or from photos and plans.
Step 2: Get Structural Calculations
The engineer works out what the wall supports and designs a steel beam (or other solution) to carry it. The output is calculations and a structural detail showing the beam size, bearings, padstones and any posts. See what size steel beam do I need.
Step 3: Building Control Approval
Submit the calculations to Building Control (council or approved inspector) before work starts. Also check whether a party wall notice applies for a shared wall.
Step 4: Temporary Support and Installation
A builder will:
- Install temporary props (Acrow props and needles) to carry loads above
- Cut pockets and install padstones at each end
- Lift and fix the steel beam
- Pack up tight with dry-pack mortar and remove props once cured
- Arrange inspection by Building Control
Steel also needs fire protection — usually plasterboard encasement.
Step 5: Making Good
Plaster, re-decorate and reinstate flooring. Cracks are common around the new opening if movement was not allowed for, which is why correct sizing and propping matter.
Replacing a Load-Bearing Stud Wall
Timber stud walls often carry more than people expect — joists, a wall above or roof load. In many cases they can be replaced:
- With a steel beam where the span is clear
- With a redesigned timber or steel frame where partial support is needed
The engineer must establish the load path first. Never remove studs "to see" without temporary support.
