About our side return extension steels service in Southall
For homes in Southall and the TW5, UB1, UB2, UB3 and UB4 districts, we handle side return extension steels from survey to sign-off. We also cover the surrounding towns and villages in London. The beam is sized by a structural engineer and inspected before it is boxed in.
Many Victorian and Edwardian terraces have a narrow back wing, often called an outrigger, with a strip of yard down one side. Infilling that strip turns a galley kitchen into a wide family room, but the outrigger's side wall usually holds up a bathroom or bedroom above, so it has to be replaced with steel.
What to expect
- The kitchen is usually out of use while the side wall comes down and the frame goes in, so many households set up a temporary kitchen elsewhere in the house. The rest of the property normally stays in use throughout the steel stage.
- Glazed roofs over side returns are usually made to measure and need an edge that stays straight and level. The engineer may set a stiffer limit on how far the steel can deflect so the glazing is not stressed once loaded.
- Fitting the steel frame for a side return usually takes a few working days on site, depending on how many beams and columns there are. It is scheduled with the builder so the new space can be roofed and weathertight soon after the old wall comes down.
- The number of beams, columns and connections drives steel cost more than the length of the side return alone. Keep the calculations, any party wall paperwork and the completion certificate together for when the house is sold.
- The side wall of a typical outrigger carries the first-floor wall above it, and sometimes the rear wing's roof and the joists of the room over the kitchen. That is why taking it out calls for a beam along its full length.
What happens, step by step
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 Southall
Structural openings in English homes need building regulations approval before work starts. The local council's building control team can deal with it, or you can use a registered building control approver. Either way the steel is inspected before it is covered, and a completion certificate is issued at the end. Keep it safe for when you sell.
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.
Local questions answered
Do you cover Southall for side return extension steels?

How much do side return extension steels cost in Southall?
As a guide, budget £4,500–£10,900 including VAT for side return extension steelwork in Southall, based on published UK cost guides adjusted for London prices (+28%). The exact figure depends on the span, what the wall carries, access and the finish, and is fixed in writing once the scope is agreed.
What steels do I need for a side return extension?
Usually a long beam along the line of the old outrigger side wall, often a second beam opening the back of the main house, and one or more columns where the loads meet. The exact arrangement depends on the house and the layout, and a structural engineer specifies every beam, column and connection.
Can a side return be built over a drain?
Sometimes, but drains in side passages need checking early. A shared or public sewer may need the water company's agreement before building over or close to it, and column foundations may have to avoid the pipe run. Manholes may need moving or adapting as part of the wider build.
Do I need planning permission for a side return extension?
It depends on the house and where it is. Some side return infills can be built under permitted development, but the rules for side extensions are restrictive, and conservation areas and listed buildings add further controls. Check with your local planning authority or architect before committing to a design.
Can you work on older or listed homes in Southall?
Yes. Older homes often have lime mortar, timber lintels or shallow footings, which the engineer allows for. Listed buildings need listed building consent for internal structural changes as well as building regulations approval, and that must be in place first.
