Kitchen-diner knock-throughs in Feltham: how it works

If you live in Feltham, kitchen-diner knock-throughs can usually be planned and priced after a single survey visit. The wider London area is covered as well. We cover TW2, TW3, TW4, TW5 and TW6, and we fix the price in writing once the layout and scope are agreed.

We plan the structural work alongside your kitchen design so the beam, any column and the services all land in the right place before units are ordered. A survey visit, engineer's calculations, building control, propping, the steel and making good are all covered in one itemised written quote, with the price fixed in writing once the layout and specification are agreed.

What to expect

  • 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.
  • If the kitchen also opens onto the hallway, the change can affect the escape route from the bedrooms. Building control checks how people would get out in a fire, and smoke alarms, a fire door or other measures may be required as part of approval.
  • 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.
  • A flush beam sits up within the depth of the ceiling so the kitchen and dining ceilings run as one flat surface. It suits continuous downlights and long runs of wall units, but each joist has to be connected into the beam, which adds labour.
  • 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.

How the job runs in Feltham

  1. Free visit

    A short visit to Feltham to see the job, agree what you want and check the bearings, floors and services that affect the design.

  2. Calculations

    The engineer's calculations and a simple drawing are prepared for your opening and shared with you before anything is ordered.

  3. 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.

  4. Steel in, made good

    On site we prop, open up, fit and pack the steel, then fire protect, box in and plaster once the inspection is done.

Building control and neighbours in Feltham

For Feltham, 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.

Terraced and semi-detached homes often need party wall notices, because cutting into a shared wall to take a beam end is notifiable under the Party Wall etc. Act 1996. Allow at least two months for the notice period unless your neighbour agrees sooner.

Local questions answered

Do you also work near Feltham?

Yes. We also cover nearby towns including Hanworth, Ashford, Hounslow and Sunbury-on-Thames.

Do I need a party wall agreement for kitchen-diner knock-throughs in Feltham?

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.

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.

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 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.

Who approves kitchen-diner knock-throughs in Feltham?

Structural work in Feltham 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.
