About our kitchen-diner knock-throughs service in Cambridge

Cambridge has a mix of housing, and kitchen-diner knock-throughs need a slightly different approach in each. The wider Cambridgeshire area is covered as well. Whatever the age of the property, the steel goes in on proper bearings with temporary support in place throughout.

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

  • 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.
  • 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.
  • 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.
  • 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.

What happens, step by step

  1. Survey in Cambridge

    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.

  2. 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.

  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. 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.

Building control and neighbours in Cambridge

Structural openings in English homes need building regulations approval before work starts. The local council's building control team can deal with it, or you can use a registered building control approver. Either way the steel is inspected before it is covered, and a completion certificate is issued at the end. Keep it safe for when you sell.

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 Cambridge

What happens at the survey visit in Cambridge?

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.

How much do kitchen-diner knock-throughs cost in Cambridge?

As a guide, budget £2,650–£6,350 including VAT for kitchen-diner knock-through in Cambridge, based on published UK cost guides adjusted for prices in the East of England (+6%). The exact figure depends on the span, what the wall carries, access and the finish, and is fixed in writing once the scope is agreed.

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.

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.

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.

Do you also work near Cambridge?

Yes. We also cover nearby towns including Newmarket, Ely, Huntingdon and Haverhill.
