Planning shop & commercial openings in Windsor
Windsor has a mix of housing, and shop & commercial openings need a slightly different approach in each. It sits about 1.8 miles from Slough, which we also cover. Whatever the age of the property, the steel goes in on proper bearings with temporary support in place throughout.
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
- 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 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.
- 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.
- 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.
- 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.
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
We submit a building notice or full plans application to Royal Borough of Windsor and Maidenhead, so approval is in place before the wall is touched.
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 Windsor
Structural openings in English homes need building regulations approval before work starts. Royal Borough of Windsor and Maidenhead 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.
Local questions answered
Do you also work near Windsor?
Yes. We also cover nearby towns including Slough, Egham, Staines and Maidenhead.
What happens at the survey visit in Windsor?
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.
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 I knock two shops into one?
Usually, yes, with the right approvals. The dividing wall is replaced with steel designed by a structural engineer, building control approves the work and the fire strategy is updated for the combined unit. You also need landlord consent if you lease either unit, and party wall notices in England and Wales if the steel bears into a wall shared with another owner.
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.
