About our side return extension steels service in Larne
Our side return extension steels service in Larne covers everything from the first visit to the completion paperwork. The wider Mid and East Antrim area is covered as well. Postcode districts we cover here include BT40.
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
- 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.
- 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.
- 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.
- 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.
Four stages, one team
Free visit
A short visit to Larne 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
A full plans application or building notice goes to Mid and East Antrim Borough Council under the Building Regulations (Northern Ireland) 2012 before work begins.
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.

Approvals in Larne
In Northern Ireland, structural work comes under the Building Regulations (Northern Ireland) 2012 and is approved by the local council's building control. For Larne that is Mid and East Antrim Borough Council. We submit a full plans application or building notice before work starts and book the inspections.
Northern Ireland has no Party Wall Act, so there is no statutory notice to serve. Where the steel bears into a shared wall, the title deeds and the general law apply, and agreeing the work with your neighbour in writing first is good practice.

How much do side return extension steels cost in Larne?
As a guide, budget £3,000–£7,300 including VAT for side return extension steelwork in Larne, based on published UK cost guides adjusted for prices in Northern Ireland (-14%). 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.
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 outrigger wall be removed without affecting the bathroom above?
Yes, when it is properly propped and replaced with steel designed for the load. The floor and wall above are supported throughout, and the bathroom stays usable in most cases. Waste pipes or soil stacks on the wall being removed are rerouted first so nothing is disturbed when it comes down.
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.
Do I need a party wall agreement for side return extension steels in Larne?
There is no Party Wall Act in Northern Ireland. Your title deeds and the general law apply instead, so agree the work with your neighbour in writing before it starts.
