Side return extension steels in Rottingdean: how it works

We carry out side return extension steels in Rottingdean, covering the BN2 postcode district. It sits about 3.7 miles from Brighton, 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.

Side returns tend to need more steel than a straight rear extension: a long beam on the old wall line, often a second beam across the back of the main house, and columns where they meet. We arrange the design, approvals and party wall notices through a surveyor, and fit the steel frame in step with the build.

What to expect

  • 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.
  • Propping a side return is awkward because space in a narrow kitchen is tight and the infill side is often open ground. Props outside may stand on temporary pads or boards, set so they do not sink or shift in wet weather.
  • 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.

Four stages, one team

  1. Survey in Rottingdean

    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 Brighton & Hove City Council, 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.

Approvals in Rottingdean

Structural openings in English homes need building regulations approval before work starts. Brighton & Hove City Council 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.

Terraced and semi-detached homes often need party wall notices, because cutting into a shared wall to take a beam end is notifiable under the Party Wall etc. Act 1996. Allow at least two months for the notice period unless your neighbour agrees sooner.

Local questions answered

Do you also work near Rottingdean?

Yes. We also cover nearby towns including Brighton, Hove, Portslade and Seaford.

Can you work on older or listed homes in Rottingdean?

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.

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.

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.

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.
