About our side return extension steels service in Durham
Need side return extension steels in Durham? We also work in nearby Sunderland, roughly 11.7 miles away. We survey the property, arrange the engineer's design, deal with Durham County Council, fit the steel and make good, all under one quote for DH1 addresses.
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.
- 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.
- 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.
- 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.
What happens, step by step
Free visit
A short visit to Durham to see the job, agree what you want and check the bearings, floors and services that affect the design.
Calculations
The engineer's calculations and a simple drawing are prepared for your opening and shared with you before anything is ordered.
Building control
We submit a building notice or full plans application to Durham County Council, so approval is in place before the wall is touched.
Steel in, made good
On site we prop, open up, fit and pack the steel, then fire protect, box in and plaster once the inspection is done.
How much should I budget in Durham?
As a guide, budget £3,250–£7,900 including VAT for side return extension steelwork in Durham, based on published UK cost guides adjusted for prices in the North East (-7%).
| Job | Typical guide range | What it usually covers |
|---|---|---|
| Side return extension steelwork | £3,250–£7,900 | Beams and posts along the old side wall line, propping and approvals (extension build extra) |
| Party wall surveyor (agreed surveyor, per neighbour) | £840–£1,860 per neighbour | Schedule of condition and award where a neighbour dissents; serving notice alone, where the neighbour consents, costs far less (England and Wales only) |
| Steel column or post | £460–£1,400 per column | Column supplied and fitted with base and cap plates on a pad foundation |
| Fire protection to a steel beam | £140–£560 per beam | Fire-rated board boxing or an intumescent coating system as specified |

Building rules for Durham
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 Durham County 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.

Local questions answered
Do I need a party wall agreement for side return extension steels in Durham?
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.
Who approves side return extension steels in Durham?
Structural work in Durham needs a building notice or full plans application to Durham County Council or a registered building control approver. We prepare and submit it with the structural engineer's calculations and arrange the inspections, so the completion paperwork follows the job.
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.
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.
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.
What happens at the survey visit in Durham?
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.
