Planning side return extension steels in Shepherds Bush

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.
Worth knowing before you start
- Victorian outrigger walls are often a single brick thick in soft lime mortar, sometimes on very shallow footings. The engineer may ask for trial holes before deciding whether new foundations are needed under the column positions or beam ends.
- Side passages often carry the house drains and rainwater pipes from the outrigger roof. Manholes and pipe runs are located early, and a shared or public sewer under the passage may need the water company's agreement before building over or near it.
- Planning rules for side return infills depend on the house and its location, and some need a full planning application rather than relying on permitted development. The steel design forms part of the building regulations approval either way.
- Many outrigger kitchens have a chimney breast on the side wall being removed or on the party wall. Its position affects where beams can bear, and if any part of the breast is taken out, what remains above has to be supported as the engineer specifies.
- Bathrooms above outriggers are common, and their floors carry baths, tiles and water. The engineer allows for those loads, and any soil pipe or waste running down the side wall is rerouted before the wall comes out.
How the job runs in Shepherds Bush
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 Shepherds Bush
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.

How much do side return extension steels cost in Shepherds Bush?
As a guide, budget £4,500–£10,900 including VAT for side return extension steelwork in Shepherds Bush, 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.
Can the steel beam be left exposed in a side return?
Yes, and many people like the look of exposed steel under a glazed roof. It usually still needs fire protection, so it is coated with an intumescent paint system to the specified thickness, then finished in your chosen colour. The engineer and building control confirm what protection is required.
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.
Can the outrigger wall be removed without affecting the bathroom above?
Yes, when it is properly propped and replaced with steel designed for the load. The floor and wall above are supported throughout, and the bathroom stays usable in most cases. Waste pipes or soil stacks on the wall being removed are rerouted first so nothing is disturbed when it comes down.
Do you also work near Shepherds Bush?
Yes. We also cover nearby towns including Notting Hill, Chiswick, Fulham and Willesden.
