Load-bearing wall removal in Streatham: how it works
We cover load-bearing wall removal in Streatham (CR4, SE21, SE27) and the streets around it. The wider London area is covered as well. Each job is designed by a structural engineer and approved through local building control before work begins.
Most homes built before the 1970s have at least one internal wall that carries the floor joists, a wall upstairs or part of the roof. Taking it out is very doable, but the weight it carries has to go somewhere. A steel beam picks that load up and passes it down through padstones into walls or columns that can take it.
What to expect
- Steel beams in homes usually need fire protection. That is often fire-rated plasterboard boxing, which also gives a neat finish, or intumescent paint where the steel is left on show.
- A beam can sit below the ceiling with a small boxed downstand or be set up into the floor void so the ceiling runs flat. A flush beam usually needs more work to the joists and costs more.
- Cables, pipes, radiators and sometimes gas runs pass through internal walls. These are traced at the survey so they can be rerouted by the right trade before or during the work, not discovered halfway through.
- Building control is needed because removing a structural wall is controlled building work. Doing it without approval can cause problems when you come to sell, and putting it right afterwards costs far more than doing it properly first time.
- Homes built before 2000 may contain asbestos in textured ceilings, boxing or old boards. Where there is a risk, a survey of the area being disturbed is arranged before the wall comes out.
How the job runs in Streatham
Look and measure
We check the wall, the span you want and what the wall is carrying, and photograph anything the engineer needs to see.
Design and price
Calculations come back from the engineer and we confirm your fixed written price, line by line.
Building control
We submit a building notice or full plans application to the local council's building control team, so approval is in place before the wall is touched.
Fit, inspect, finish
The work is propped and the steel installed and packed tight. After inspection the opening is boxed, plastered and left clean.

Approvals in Streatham
In England, taking out a load-bearing wall or putting in a beam is building work under the Building Regulations 2010. It needs approval from building control, either the local council's building control team or a registered building control approver, through a full plans application or a building notice. Part A covers the structure and Part B covers fire safety, which is why steel in homes is usually fire protected.
If the beam bears into a wall you share with a neighbour, the Party Wall etc. Act 1996 applies, and a party structure notice must be served at least two months before that work starts. We arrange this through a party wall surveyor.
Questions about load-bearing wall removal in Streatham
Can I stay at home while the work is done in Streatham?
Usually, yes. The work area is screened and floors are protected. The rooms either side of the opening are out of action for a few days, and there is some noise and dust while the masonry comes out.
Do I need a party wall agreement for load-bearing wall removal in Streatham?
Yes, if the beam bears into a shared wall: the Party Wall etc. Act 1996 applies in England and Wales, and a party structure notice must be served at least two months before that work starts. We arrange it through a party wall surveyor.
Do I need building regulations approval to remove a load-bearing wall?
Yes. In England removing a structural wall is building work that needs building control approval, through a full plans application or a building notice. In Wales it needs an application under the Welsh regulations. In Scotland it needs a building warrant before work starts, and in Northern Ireland the council's building control must receive a full plans application or, for an existing single dwelling, a building notice before work starts. We arrange this as part of the job.
Is a steel beam better than a concrete lintel?
For short openings in some walls a lintel can be enough, but wide openings carrying floors or walls above normally need steel. The engineer chooses whatever does the job properly. Steel is common because it carries a lot of load for its depth.
Do I need planning permission to remove an internal wall?
Usually not, because internal alterations to a house are not normally development needing planning permission. Listed buildings are different and need listed building consent, and flats normally need the freeholder's or landlord's written consent.
What happens at the survey visit in Streatham?
We look at the wall, the floor and ceiling either side and what sits above, measure the opening you want, and note cables, pipes and access for the steel. It usually takes under an hour and there is no charge.
