Shop & commercial openings in Morden: how it works
We carry out shop & commercial openings in Morden, covering the CR4, KT3, KT4, SM1 and SM3 postcode districts. Our coverage runs across London, so nearby villages are included too. The job starts with a free survey visit so the engineer's calculations are based on your actual walls, floors and loads.
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
- 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.
- 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.
- 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.
- 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.
- 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.
From survey to sign-off in Morden
Survey in Morden
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 Morden
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 Morden
What happens at the survey visit in Morden?
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 you cover Morden for shop & commercial openings?
Yes. We carry out shop & commercial openings in Morden and the CR4, KT3, KT4, SM1 and SM3 postcode districts. Book a free survey visit and we will check the wall, arrange the engineer's calculations and send an itemised written quote.
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 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 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.
