What side return extension steels involve in Portrush
We carry out side return extension steels in Portrush, covering the BT55 and BT56 postcode districts. Our coverage runs across Causeway Coast and Glens, so nearby villages are included too. The job starts with a free survey visit so the engineer's calculations are based on your actual walls, floors and loads.
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.
What to expect
- 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.
- 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.
- Victorian outrigger walls are often a single brick thick in soft lime mortar, sometimes on very shallow footings. The engineer may ask for trial holes before deciding whether new foundations are needed under the column positions or beam ends.
- 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.
What happens, step by step
Free visit
A short visit to Portrush 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 Causeway Coast and Glens Borough Council under the Building Regulations (Northern Ireland) 2012 before work begins.

Approvals in Portrush
In Northern Ireland, structural work comes under the Building Regulations (Northern Ireland) 2012 and is approved by the local council's building control. For Portrush that is Causeway Coast and Glens Borough Council. We submit a full plans application or building notice before work starts and book the inspections.
The Party Wall etc. Act does not extend to Northern Ireland. Shared walls are dealt with under your title and the general law, so we recommend agreeing access and the work with your neighbour before it starts.

Side return extension steels in Portrush: your questions
Do you cover Portrush for side return extension steels?
Yes. We carry out side return extension steels in Portrush and the BT55 and BT56 postcode districts. Book a free survey visit and we will check the wall, arrange the engineer's calculations and send an itemised written quote.
Do you also work near Portrush?
Yes. We also cover nearby towns including Coleraine, Ballymoney, Ballycastle and Limavady.
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.
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.
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 you work on older or listed homes in Portrush?
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.
