Planning side return extension steels in Portslade

Portslade has a mix of housing, and side return extension steels need a slightly different approach in each. Portslade is around 3.5 miles from Brighton, and we cover both. Whatever the age of the property, the steel goes in on proper bearings with temporary support in place throughout.

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.
  • 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.
  • 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.
  • 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.
  • 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.

From survey to sign-off in Portslade

  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 a building notice or full plans application to Brighton & Hove City Council, so approval is in place before the wall is touched.

  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.

Approvals in Portslade

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 Brighton & Hove City Council 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 side return extension steels in Portslade

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

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.

What happens at the survey visit in Portslade?

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 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.

Why does a side return need columns?

Columns are used where two beams meet or where there is not enough solid wall to carry the end of a beam. The column takes the concentrated load down to a pad foundation in the ground. Sometimes it can be hidden in a wall nib or boxed in neatly.

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.
