What shop & commercial openings involve in Conwy
Shop and commercial openings are structural alterations in retail, office, café and light industrial premises: forming a new or wider shopfront, joining two units through a dividing wall, or removing internal walls for open floor space. A steel beam or frame, designed by a structural engineer, carries the floors and walls above, with the work approved by building control.
Across Conwy, shop & commercial openings usually come up when people want more light, a better layout or a way through to a new extension. Coverage takes in Colwyn Bay, Llandudno and Abergele and everywhere in between. Whatever the reason, the beam is sized from calculations and the work is inspected before anything is covered.
What to expect
- 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.
- A straightforward shopfront beam replacement can take a few days on site, while joining two units with several openings may run to a couple of weeks. The programme is agreed in writing before work starts so you can plan trading around it.
- 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.
- Many shopfronts sit under an old steel or timber beam hidden behind the fascia for decades. It may be corroded, undersized for what is above or bearing on decayed masonry, so it is opened up and checked before keeping it is even considered.
- 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.
Four stages, one team
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
We submit the application or notice to Conwy County Borough Council under the Building Regulations as they apply in Wales, before work starts.
Fit, inspect, finish
The work is propped and the steel installed and packed tight. After inspection the opening is boxed, plastered and left clean.

Building control and neighbours in Conwy
In Wales, structural alterations come under the Building Regulations 2010 as they apply in Wales. Conwy County Borough Council handles building control for Conwy. For work started or approved from 1 July 2026, the Welsh system uses an application to building control, dutyholders appointed in writing, a commencement notice before work starts and a compliance statement at the end.
Where the steel bears into a wall shared with next door, notice must be served under the Party Wall etc. Act 1996. If your neighbour dissents, surveyors agree how the work is done before it starts.

Shop & commercial openings in Conwy: your questions
Do I need a party wall agreement for shop & commercial openings in Conwy?
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.
How much do shop & commercial openings cost in Conwy?
As a guide, budget £4,550–£13,650 including VAT for shop or commercial structural opening in Conwy, based on published UK cost guides adjusted for prices in Wales (-9%). 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 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.
Does the beam above my shop window need replacing?
Not always, but it should be checked. Many shopfronts sit under an old steel, timber or concrete beam hidden behind the fascia, which may have corroded, rotted or been undersized for the wall above. An engineer inspects it once it is opened up and decides whether it can be kept, strengthened or must be replaced.
Do I need planning permission for a new shop front?
Often, yes. A new or altered shopfront usually changes how the building looks from the street, which can need planning permission, especially in a conservation area. Purely internal openings generally do not, but listed buildings need listed building consent for structural changes inside or out. It is worth checking with the local planning authority early.
Do I need an asbestos survey before work on my shop?
Usually, if the building dates from before 2000. The duty holder for commercial premises should already have an asbestos register, and before walls, ceilings or the shopfront are opened up, a refurbishment survey of the work area is needed wherever that register does not cover it, so any asbestos is dealt with first.
