About our side return extension steels service in Totton

We carry out side return extension steels in Totton, covering the SO40 postcode district. It sits about 3.9 miles from Southampton, which we also cover. The job starts with a free survey visit so the engineer's calculations are based on your actual walls, floors and loads.

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.

Key points for your project

  • Where the beam along the old side wall meets a beam across the main house, the junction carries a heavy point load. The engineer usually details a column or a bolted connection there, which needs a solid foundation beneath it.
  • 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.
  • 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.
  • 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.
  • 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.

How the job runs in Totton

  1. Survey in Totton

    We visit, look at the wall and what sits above it, measure the opening and note services, access and how the steel can be brought in.

  2. Engineer's design

    A structural engineer sizes the beam, padstones and any posts, and sets out the temporary support needed while the wall is out.

  3. 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.

  4. Install and sign-off

    Props go in, the opening is formed, the steel is set and packed, building control inspects it, and we make good.

Building control and neighbours in Totton

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.

Local questions answered

What happens at the survey visit in Totton?

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.

Do you cover Totton for side return extension steels?

Yes. We carry out side return extension steels in Totton and the SO40 postcode districts. Book a free survey visit and we will check the wall, arrange the engineer's calculations and send an itemised written quote.

Do I need a party wall agreement for a side return extension?

In England and Wales it is very likely. Building on or near the boundary, excavating close to the neighbour's foundations or cutting into a shared wall can all be notifiable under the Party Wall etc. Act 1996. Notices are arranged through a party wall surveyor on your behalf, and we do not give legal advice.

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.

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.

Do you also work near Totton?

Yes. We also cover nearby towns including Southampton, Hythe, Eastleigh and Winchester.
