Planning kitchen-diner knock-throughs in Neath Port Talbot

Kitchen-diner knock-throughs remove the wall between a kitchen and a dining room to create one open-plan room, with a steel beam carrying whatever the wall supported. The work is planned around the kitchen itself: gas, water, waste and extraction runs, where units and any island will go, and how the ceiling should look once the steel is in.

Kitchen-diner knock-throughs in Neath Port Talbot follows the same careful process wherever the property is: a survey, an engineer's design, the right approval and safe temporary works. We work in Neath and Briton Ferry and the surrounding villages. We price it all up front so there are no surprises once the wall is open.

Things to plan for

  • 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.
  • 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.
  • 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.
  • 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.
  • 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.

What happens, step by step

  1. Survey in Neath Port Talbot

    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 the application or notice to Neath Port Talbot County Borough Council under the Building Regulations as they apply in Wales, before work starts.

  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.

Local questions answered

Which towns in Neath Port Talbot do you cover?

We cover towns including Neath and Briton Ferry, plus the villages and smaller towns around them.

What happens at the survey visit in Neath Port Talbot?

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.

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.

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.

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.

Who moves the gas pipe for my cooker?

A Gas Safe registered engineer, because work on gas pipework must legally be done by one. If the pipe runs in or near the wall being removed, it is capped or rerouted before demolition starts and reconnected once the new layout is in place. We build this into the programme so it is not left to chance.
