The wall between a kitchen and dining room is often a structural one, especially in semi-detached and terraced houses where it carries the floor joists for the bedrooms above. Opening it up gives the sociable, open-plan space most families want, but the kitchen brings extra things to plan: pipes, cables, an extractor, and a layout that has to work around the new steel.
What to expect
- Taking the wall out removes the switches and sockets on it, and an open-plan room usually needs a new lighting layout. Electrical work in England must comply with Part P of the building regulations where it is notifiable, so rewiring is planned early.
- Where the wall stood there is usually a strip of footing or a change in floor level between the two rooms. It is levelled with screed or timber so one continuous floor finish, such as tiles or engineered boards, can run straight across.
- Sinks and dishwashers usually sit on an outside wall, but supply pipes and waste runs sometimes cross the internal wall. Moving the sink to an island means planning a waste route with enough fall under the floor, which affects how the floor is prepared.
- Keep the structural calculations, the building control completion certificate and any gas or electrical certificates together. When the house is sold, the buyer's solicitor will usually ask for evidence that the knock-through was approved and signed off.
- In many houses the kitchen and dining room wall carries the bedroom floor joists, and sometimes a bathroom wall above. Lifting a floorboard upstairs to see which way the joists run is a useful first look, though the engineer confirms what the wall actually supports.
How the job runs in Wallington
Survey in Wallington
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.

Approvals in Wallington
For Wallington, building control is provided by the local council's building control team, 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.
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 kitchen-diner knock-throughs in Wallington
Can you work on older or listed homes in Wallington?
Yes. Older homes often have lime mortar, timber lintels or shallow footings, which the engineer allows for. Listed buildings need listed building consent for internal structural changes as well as building regulations approval, and that must be in place first.
Who approves kitchen-diner knock-throughs in Wallington?
Structural work in Wallington needs a building notice or full plans application to the local council's building control team or a registered building control approver. We prepare and submit it with the structural engineer's calculations and arrange the inspections, so the completion paperwork follows the job.
Is the wall between my kitchen and dining room load-bearing?
It often is, particularly in older semis and terraces where it supports the bedroom floor joists. The clearest signs are joists bearing on it from above and a wall in the same position upstairs, but only an engineer's site check confirms it. We arrange that check as part of the survey and design stage.
Can I have a kitchen island where the wall used to be?
Often you can, but it depends on whether the engineer needs a column and where the beam ends bear. If an island is part of the plan, tell us at the survey so the steel can be designed around it. Plumbing or power to an island also needs a route under the floor.
Can I knock my kitchen and dining room into one?
In most houses, yes. The wall can be removed even if it is load-bearing, as long as a steel beam designed by a structural engineer takes over the load and building control approves the work. The main things to check early are what the wall carries, where services run, and whether the layout still works around any column.
Do I need a party wall agreement for kitchen-diner knock-throughs in Wallington?
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.
