Shop & commercial openings in Coleraine: how it works
Shop & commercial openings in Coleraine are planned around the house, not a standard kit. Our coverage runs across Causeway Coast and Glens, so nearby villages are included too. We visit, measure and check what the wall carries, then arrange calculations and building control approval before any steel is ordered.
Commercial buildings often have a flat or offices above the shop, a heavy brick front and old steel or timber over the existing shopfront. Opening them up means supporting a lot of load at street level, usually with the public walking past, while keeping disruption to trading as low as possible.
Key points for your project
- Commercial premises often have three-phase power, alarm and data cabling, gas supplies and drainage running through the walls being altered. These are mapped at the survey, and any work on gas pipes must by law be done by a Gas Safe registered engineer.
- Commercial openings tend to need longer, heavier steel than domestic work. Deliveries are planned around loading restrictions, and sections may be lifted with a small crane, telehandler or chain hoist, or spliced and bolted in place where the engineer allows.
- Most commercial leases prohibit structural alterations without the landlord's written consent, often given as a licence for alterations. Securing it before work starts avoids disputes later, and we supply the drawings and calculations the landlord or their surveyor asks to see.
- Joining two units can change the fire strategy. The wall between them may be a compartment wall, escape routes and travel distances alter, and the steel needs fire protection to the required period. The fire risk assessment should be updated to match the new layout.
- The main cost factors are the span and load above, whether columns or a goalpost frame are needed, the temporary works at the street, out-of-hours working, lifting equipment, and the fire protection and finish the opening requires.

Building control and neighbours in Coleraine
In Northern Ireland, structural work comes under the Building Regulations (Northern Ireland) 2012 and is approved by the local council's building control. For Coleraine that is Causeway Coast and Glens 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.

Local questions answered
How much do shop & commercial openings cost in Coleraine?
As a guide, budget £4,300–£12,900 including VAT for shop or commercial structural opening in Coleraine, 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.
Do I need a party wall agreement for shop & commercial openings in Coleraine?
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.
Do I need my landlord's permission to put in a steel beam?
Almost certainly, if you lease the premises. Most commercial leases forbid structural alterations without the landlord's written consent, usually given as a licence for alterations. We can supply the engineer's calculations and drawings your landlord asks for, though the lease terms themselves are a matter for you and your solicitor.
What kind of steel is used for a wide shop front?
The engineer chooses the section to suit the span and load. Wide frontages often use universal beams, sometimes paired or plated, and a goalpost frame of two columns and a beam where the existing piers cannot take the load. The steel is then fire protected and finished behind the fascia or boxing.
Can commercial steel beam work be done outside opening hours?
In many cases, yes. Noisy cutting and the main structural stages can be programmed for evenings, early mornings or weekends where the landlord, the building and neighbouring occupiers allow. Out-of-hours working is priced as a separate line on the itemised quote, so you can weigh it against closing for part of the job.
