About our shop & commercial openings service in Thamesmead
Planning shop & commercial openings in Thamesmead? Our team covers DA16, DA17, DA18, IG11 and RM9 and the streets around them. The wider London area is covered as well. You get one written quote for the calculations, approvals, propping, steel and making good.
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.
Things to plan for
- 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.
- 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.
- Most commercial leases prohibit structural alterations without the landlord's written consent, often given as a licence for alterations. Securing it before work starts avoids disputes later, and we supply the drawings and calculations the landlord or their surveyor asks to see.
- Plenty of businesses keep trading while the work goes on. Dust screens, hoarding and phased working can keep part of the premises open, and the noisiest cutting can be programmed outside opening hours where the building and neighbours allow.
- 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.
Four stages, one team
Survey in Thamesmead
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 rules for Thamesmead
In England, taking out a load-bearing wall or putting in a beam is building work under the Building Regulations 2010. It needs approval from building control, either the local council's building control team or a registered building control approver, through a full plans application or a building notice. Part A covers the structure and Part B covers fire safety, which is why steel in homes is usually fire protected.
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.
Questions about shop & commercial openings in Thamesmead
How soon can shop & commercial openings start in Thamesmead?
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.
Can I stay at home while the work is done in Thamesmead?
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.
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 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.
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 a party wall agreement for shop & commercial openings in Thamesmead?
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.
