About our side return extension steels service in Dunoon
Side return extension steels in Dunoon are planned around the house, not a standard kit. We also cover the surrounding towns and villages in Argyll and Bute. We visit, measure and check what the wall carries, then arrange calculations and building warrant before any steel is ordered.
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
- 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.
- 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 a building warrant either way.
- 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.
- 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 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.
What happens, step by step
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.
Design and price
Calculations come back from the engineer and we confirm your fixed written price, line by line.
Building warrant
A building warrant is applied for from Argyll and Bute Council, and work starts only once the warrant has been granted.
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 Dunoon
Steel beam work in Dunoon needs a building warrant from Argyll and Bute Council. The structural design is part of the application, and the council's building standards team accepts the completion certificate once the work is done as approved.
There is no party wall notice system in Scotland. Instead, check your title deeds and, for flats, the tenement management scheme, and talk to neighbours early if the beam bears into a shared wall.

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.
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 standards confirm what protection is required.
Do I need a party wall agreement for side return extension steels in Dunoon?
There is no Party Wall Act in Scotland. Your title deeds and the general law apply instead, and the Tenements (Scotland) Act 2004 for flats, so agree the work with your neighbour in writing before it starts.
