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

For homes in Purley and the CR0, CR2, CR5, CR8 and CR9 districts, we handle kitchen-diner knock-throughs from survey to sign-off. Our coverage runs across London, so nearby villages are included too. The beam is sized by a structural engineer and inspected before it is boxed in.

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.

Things to plan for

  • Settle the kitchen layout before the steel is designed. If the engineer needs a column or a deeper beam, it is far easier to plan an island, tall units or the hob position around it at drawing stage than after the units are ordered.
  • 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.
  • 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.
  • 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.

Four stages, one team

  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.

Approvals in Purley

For Purley, 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.

Questions about kitchen-diner knock-throughs in Purley

Do you also work near Purley?

Yes. We also cover nearby towns including Coulsdon, South Croydon, Wallington and Carshalton.

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

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.

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.

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.

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

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.
