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

We carry out kitchen-diner knock-throughs in Finchley, covering the N2, N3, N10, N12 and N20 postcode districts. We also cover the surrounding towns and villages in London. The job starts with a free survey visit so the engineer's calculations are based on your actual walls, floors and loads.

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.

Things to plan for

  • 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.
  • While the wall is out you will usually be without a working kitchen for several days. Many households set up a kettle, microwave and fridge in another room for that period and plan simple meals that need little cooking.
  • Older kitchens can hide asbestos in textured ceiling coatings, floor tiles, boxing around pipes or the backing of old heaters. In buildings from before 2000 it must be identified before the fabric is disturbed, so a survey of the affected area is arranged first.
  • 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.
  • 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.

From survey to sign-off in Finchley

  1. 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.

  2. Design and price

    Calculations come back from the engineer and we confirm your fixed written price, line by line.

  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. 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 rules for Finchley

For Finchley, 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.

Kitchen-diner knock-throughs in Finchley: your questions

Who approves kitchen-diner knock-throughs in Finchley?

Structural work in Finchley 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.

What happens at the survey visit in Finchley?

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.

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.

How long will I be without a kitchen?

The structural work itself usually takes three to six working days, and the kitchen is out of action during that time. After that come plastering, drying, flooring and the kitchen fit, so the overall period without a finished kitchen depends mostly on your fitter's programme and when the units are delivered.

Can I stay at home while the work is done in Finchley?

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.
