Planning side return extension steels in East Dunbartonshire

Side return extension steels are the beams and columns that replace the side wall of a terraced house's rear wing when the narrow passage beside it is built over. Sized by a structural engineer, they carry the wall, floor and roof loads above along the line of the old wall, so the kitchen and the infilled side return become one wide room.

From the first survey visit to the completion certificate, we take care of side return extension steels across East Dunbartonshire. Towns we cover include Bishopbriggs, Kirkintilloch and Bearsden, among other places in the area. The engineer sizes the steel, we deal with East Dunbartonshire Council, and our team fits and packs the beam before making good.

What to expect

  • 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.
  • 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.
  • 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.
  • 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.
  • 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.

What happens, step by step

  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 warrant

    A building warrant is applied for from East Dunbartonshire Council, and work starts only once the warrant has been granted.

  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.

Figures include our approximate regional adjustment for prices in Scotland (-9%) and are rounded. How these figures are worked out.

Building control and neighbours in East Dunbartonshire

In Scotland, structural alterations need a building warrant under the Building (Scotland) Act 2003, and work must not start until the warrant is granted. For East Dunbartonshire, warrants are handled by East Dunbartonshire Council's building standards service. When the work is finished, a completion certificate is submitted and has to be accepted by the council.

Scotland has no Party Wall Act. Work affecting a shared wall is governed by your title deeds and the general law, and in flats by the Tenements (Scotland) Act 2004, so it is sensible to agree the work with neighbours in writing before starting.

Side return extension steels by town

Side return extension steels in East Dunbartonshire: your questions

How much do side return extension steels cost in East Dunbartonshire?

As a guide, budget £3,200–£7,750 including VAT for side return extension steelwork in East Dunbartonshire, based on published UK cost guides adjusted for prices in Scotland (-9%). 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.

Which towns in East Dunbartonshire do you cover?

We cover towns including Bearsden, Bishopbriggs and Kirkintilloch, plus the villages and smaller towns around them.

Does a glazed roof affect the steel beam?

Yes. Glazed roofs need the beam they sit on to stay very straight under load, so the engineer may set a stricter deflection limit than for a solid roof. That can mean a deeper or heavier steel section, and the roof supplier's details need sharing early.

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.

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.

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.
