- Installing steel beams (RSJs) with padstones and fire protection.
- Underpinning and foundation repair.
- Basement lowering and conversion.
- New openings for doors and windows in masonry walls.
Why an engineer comes first
You cannot tell by looking whether a wall is load-bearing. A structural engineer confirms what the wall carries, designs the beam and specifies bearings. Their calculations are submitted to building control, and we build exactly to them.
We coordinate engineers and building control, so you do not need to manage them. If you already have an engineer or architect, we work from their drawings.
How a wall is removed safely
- Temporary propping holds the floor and roof loads above.
- The opening is cut in stages and the steel beam is lifted into place on padstones.
- Packing, fire protection and making good follow once the load is transferred.
- Building control inspects the beam and bearings before they are covered.
Dust, noise and the removal of rubble are planned in advance, so the rest of the house stays usable wherever possible.
Building regulations and party walls
Structural alterations require Building Regulations approval. Where work affects a shared wall, or underpinning and basement work is close to a neighbouring building, the Party Wall etc. Act 1996 may apply. We coordinate party wall surveyors and notices where the work requires them.
Common questions
Yes. Removing a load-bearing wall is a structural alteration, and the beam design and installation are inspected by building control.
Only a structural engineer can confirm it, usually after opening up small sections. We arrange the engineer's visit as part of the survey.
A rolled steel joist, the steel beam that carries the load above a removed wall or a new opening. Its size depends on the span and what it supports.
Yes. Basement lowering and conversion are part of our structural work, subject to engineering design, party wall matters and building control approval.
