What kitchen-diner knock-throughs involve in Ammanford

For homes in Ammanford and the SA18 district, we handle kitchen-diner knock-throughs from survey to sign-off. Our coverage runs across Carmarthenshire, 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.

Key points for your project

  • 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.
  • The structural work comes first, then first-fix electrics and plumbing, plastering, flooring and finally the kitchen fit. Booking the kitchen fitter only once the beam has passed inspection and the plaster has dried avoids units going onto damp walls.
  • 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.
  • A gas hob or cooker supply often runs along or through the wall being removed. By law, any work on gas pipework must be carried out by a Gas Safe registered engineer, so the pipe is capped or rerouted by one before the wall comes down.

From survey to sign-off in Ammanford

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

  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 control and neighbours in Ammanford

In Wales, structural alterations come under the Building Regulations 2010 as they apply in Wales. Carmarthenshire County Council handles building control for Ammanford. For work started or approved from 1 July 2026, the Welsh system uses an application to building control, dutyholders appointed in writing, a commencement notice before work starts and a compliance statement at the end.

The Party Wall etc. Act 1996 applies in Wales as well as England, so a beam bearing into a shared wall needs a party structure notice at least two months before work starts. We arrange notices through a party wall surveyor.

Kitchen-diner knock-throughs in Ammanford: your questions

Do you also work near Ammanford?

Yes. We also cover nearby towns including Llandeilo, Clydach, Gorseinon and Ystradgynlais.

Can you work on older or listed homes in Ammanford?

Yes. Older homes often have lime mortar, timber lintels or shallow footings, which the engineer allows for. Listed buildings need listed building consent for internal structural changes as well as building regulations approval, and that must be in place first.

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.

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.

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.

What happens at the survey visit in Ammanford?

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.
