About our shop & commercial openings service in Derry/Londonderry
Need shop & commercial openings in Derry/Londonderry? The wider Derry City and Strabane area is covered as well. We survey the property, arrange the engineer's design, deal with Derry City and Strabane District Council, fit the steel and make good, all under one quote for BT47 and BT48 addresses.
We carry out structural openings for small commercial premises across the UK, working to an engineer's design and handling building control. Work can be planned around opening hours, including out-of-hours shifts where the landlord and building allow, and coordinated with your shopfitter.
What to expect
- 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.
- Commercial buildings built before 2000 should already have an asbestos register under the duty to manage. Before walls or ceilings are opened up, the register is checked and a refurbishment survey of the work area is arranged where it does not cover the job.
- Where there is a flat above the shop, its occupants need to know about the works and their safety has to be protected. Their access, fire escape route and the structure holding up their floor must all be maintained throughout the job.
- Purely internal works may not need planning permission, but a new or altered shopfront changes the look of the building and may need it, particularly in a conservation area. Listed commercial buildings also need listed building consent for structural changes.
- Shop buildings commonly have a full-height brick wall above the shopfront carrying upper floors and the roof. The engineer designs for that load, plus any point loads from chimney stacks or columns, and may specify a compound section or a steel frame.
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 control
A full plans application or building notice goes to Derry City and Strabane District Council under the Building Regulations (Northern Ireland) 2012 before work begins.
Fit, inspect, finish
The work is propped and the steel installed and packed tight. After inspection the opening is boxed, plastered and left clean.

Approvals in Derry/Londonderry
Building control in Derry/Londonderry is run by Derry City and Strabane District Council. Beams and new openings are controlled work under the Northern Ireland regulations, so we apply before anything is removed and the steel is inspected before it is covered.
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.
Shop & commercial openings in Derry/Londonderry: your questions
Can you work on older or listed homes in Derry/Londonderry?
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.
Do you cover Derry/Londonderry for shop & commercial openings?
Yes. We carry out shop & commercial openings in Derry/Londonderry and the BT47 and BT48 postcode districts. Book a free survey visit and we will check the wall, arrange the engineer's calculations and send an itemised written quote.
Will I have to close my shop while the work is done?
Not always. Depending on the layout, the work area can be screened off with hoarding so part of the premises keeps trading, and the noisiest stages can be done out of hours. Some jobs, such as replacing the beam across the whole frontage, may need a short closure, which is planned well in advance.
How does fire safety change when two units are joined?
It can change significantly. The wall between the units may have been a compartment wall, escape routes and travel distances alter, and the new steel needs fire protection to the required period. Building control assesses this as part of the application, and the fire risk assessment for the premises should be updated for the new layout.
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.
Do I need a party wall agreement for shop & commercial openings in Derry/Londonderry?
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.
