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

Kitchen-diner knock-throughs in Redhill are planned around the house, not a standard kit. Redhill is around 8.8 miles from Crawley, and we cover both. We visit, measure and check what the wall carries, then arrange calculations and building control approval before any steel is ordered.

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

  • 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.
  • 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.
  • 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.
  • Taking the wall out removes the switches and sockets on it, and an open-plan room usually needs a new lighting layout. Electrical work in England must comply with Part P of the building regulations where it is notifiable, so rewiring is planned early.
  • 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.

What happens, step by step

  1. Free visit

    A short visit to Redhill 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 rules for Redhill

For Redhill, 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 Redhill

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

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

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.

Do I need permission from my landlord or freeholder to open up a kitchen?

If you own a leasehold flat, usually yes. The lease will normally require the freeholder's or landlord's written consent for structural alterations, so get that before any work is booked. Freehold houses do not need this, and planning permission is not normally needed for internal changes unless the building is listed.

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 the steel beam be hidden in the ceiling?

Yes, a flush beam can be set into the ceiling void so there is no step between the kitchen and dining ceilings. It needs enough joist depth and more labour to connect the joists to the steel, so it costs more than a downstand. The engineer confirms whether it is possible in your house.
