What shop & commercial openings involve in Horsham
If you live in Horsham, shop & commercial openings can usually be planned and priced after a single survey visit. We also work in nearby Crawley, roughly 7.2 miles away. We cover RH12 and RH13, and we fix the price in writing once the layout and scope are agreed.
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
- 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.
- 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.
- 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.
- 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.
- 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.
From survey to sign-off in Horsham
Survey in Horsham
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 the local council's building control team, 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.

Building control and neighbours in Horsham
Structural openings in English homes need building regulations approval before work starts. The local council's building control team can deal with it, or you can use a registered building control approver. Either way the steel is inspected before it is covered, and a completion certificate is issued at the end. Keep it safe for when you sell.
If the beam bears into a wall you share with a neighbour, the Party Wall etc. Act 1996 applies, and a party structure notice must be served at least two months before that work starts. We arrange this through a party wall surveyor.

Shop & commercial openings in Horsham: your questions
Do I need a party wall agreement for shop & commercial openings in Horsham?
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.
What happens at the survey visit in Horsham?
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.
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.
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.
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.
How soon can shop & commercial openings start in Horsham?
Start dates depend on the engineer's calculations, the building control approval and, where needed, party wall notice periods. We give you a realistic timetable after the survey and keep you updated as each approval comes through.
