What kitchen-diner knock-throughs involve in Wembley
Our kitchen-diner knock-throughs service in Wembley covers everything from the first visit to the completion paperwork. Our coverage runs across London, so nearby villages are included too. Postcode districts we cover here include HA0, HA1, HA3, HA9 and NW10.
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
- Cooker hood ducting that currently runs out through the wall may need a new route once the wall goes. Ducting can often be run in the ceiling void alongside the beam, but the beam's position and depth need to be known first.
- The structural price depends mainly on the span, what sits above and how the beam ends are supported. Kitchen-related extras, such as moving gas, relocating a soil pipe or rerouting ducting, are listed as separate items so you can see what each one adds.
- 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.
- The structural work comes first, then first-fix electrics and plumbing, plastering, flooring and finally the kitchen fit. Booking the kitchen fitter only once the beam has passed inspection and the plaster has dried avoids units going onto damp walls.
How the job runs in Wembley
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 the local council's building control team, 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 Wembley
For Wembley, 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 Wembley
Can I stay at home while the work is done in Wembley?
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 you cover Wembley for kitchen-diner knock-throughs?
Yes. We carry out kitchen-diner knock-throughs in Wembley and the HA0, HA1, HA3, HA9 and NW10 postcode districts. Book a free survey visit and we will check the wall, arrange the engineer's calculations and send an itemised written quote.
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.
What does a kitchen-diner knock-through quote include?
Our written quote is itemised: survey, engineer's calculations, building control, propping, removal of the wall, steel and padstones, fire protection, floor levelling and making good, with any gas, plumbing or electrical rerouting listed separately. Once the layout, specification and scope are agreed, the price is fixed in writing.
Should I do the knock-through before or after fitting a new kitchen?
Before. The steel, any column, the floor levelling and the plastering all need to be finished first, so the kitchen fitter works in a dry, square room with services already in position. Fitting units and then taking out a wall risks damage and rework, and the beam position can affect where wall units go.
How soon can kitchen-diner knock-throughs start in Wembley?
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.
