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.

Things to plan for

  • 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.
  • 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.
  • 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.
  • Some owners leave the long beam on show as a feature under a glazed roof. Exposed steel still needs fire protection where building control requires it, which usually means a specified intumescent paint system applied to the correct thickness.
  • 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.

From survey to sign-off in Welshpool

  1. 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.

  2. Design and price

    Calculations come back from the engineer and we confirm your fixed written price, line by line.

  3. Building control

    We submit the application or notice to Powys County Council under the Building Regulations as they apply in Wales, before work starts.

  4. Fit, inspect, finish

    The work is propped and the steel installed and packed tight. After inspection the opening is boxed, plastered and left clean.

Building control and neighbours in Welshpool

Removing a load-bearing wall in Wales needs approval under the Welsh building regulations before work starts. For Welshpool the application goes to Powys County Council or a registered building control approver, with the engineer's calculations, and a completion certificate follows the final inspection.

The Party Wall etc. Act 1996 applies in Wales as well as England, so a beam bearing into a shared wall needs a party structure notice at least two months before work starts. We arrange notices through a party wall surveyor.

Side return extension steels in Welshpool: your questions

Can you work on older or listed homes in Welshpool?

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.

What happens at the survey visit in Welshpool?

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.

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.

How long does it take to fit side return steels?

Most side return steel frames take two to five working days on site, depending on the number of beams and columns and how easy access is. That covers propping, removing the old side wall, fitting the steels and packing them. Fire protection and finishes follow afterwards.

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.
