What shop & commercial openings involve in Portslade
For homes in Portslade and the BN3 and BN41 districts, we handle shop & commercial openings from survey to sign-off. Portslade is around 3.5 miles from Brighton, and we cover both. The beam is sized by a structural engineer and inspected before it is boxed in.
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.
Worth knowing before you start
- Structural alterations to commercial premises need building regulations approval just as homes do, and in Scotland a building warrant before work starts. In England they usually go through a full plans application, because fire safety is assessed alongside the structure.
- 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.
- Supporting a shopfront means temporary works right at the street edge. Permission from the highway authority may be needed for hoarding, scaffolding or a lifting vehicle on the pavement, and props are positioned so the public route stays safe.
- 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.
- 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.
How the job runs in Portslade
Survey in Portslade
We visit, look at the wall and what sits above it, measure the opening and note services, access and how the steel can be brought in.
Engineer's design
A structural engineer sizes the beam, padstones and any posts, and sets out the temporary support needed while the wall is out.
Building control
We submit a building notice or full plans application to Brighton & Hove City Council, so approval is in place before the wall is touched.
Install and sign-off
Props go in, the opening is formed, the steel is set and packed, building control inspects it, and we make good.

Approvals in Portslade
For Portslade, building control is provided by Brighton & Hove City Council, or by a registered building control approver if preferred. We send them the engineer's calculations with a building notice or full plans application and book the inspections. Work done without approval can cause problems at sale and is far dearer to put right later.
Terraced and semi-detached homes often need party wall notices, because cutting into a shared wall to take a beam end is notifiable under the Party Wall etc. Act 1996. Allow at least two months for the notice period unless your neighbour agrees sooner.

Questions about shop & commercial openings in Portslade
What happens at the survey visit in Portslade?
We look at the wall, the floor and ceiling either side and what sits above, measure the opening you want, and note cables, pipes and access for the steel. It usually takes under an hour and there is no charge.
How much do shop & commercial openings cost in Portslade?
As a guide, budget £5,600–£16,800 including VAT for shop or commercial structural opening in Portslade, based on published UK cost guides adjusted for prices in the South East (+12%). 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.
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.
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.
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.
Can I stay at home while the work is done in Portslade?
Usually, yes. The work area is screened and floors are protected. The rooms either side of the opening are out of action for a few days, and there is some noise and dust while the masonry comes out.
