About our kitchen-diner knock-throughs service in Gorseinon

For homes in Gorseinon and the SA4 district, we handle kitchen-diner knock-throughs from survey to sign-off. The wider Swansea area is covered as well. The beam is sized by a structural engineer and inspected before it is boxed in.

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.

Key points for your project

  • 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 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.
  • 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.
  • Where the wall stood there is usually a strip of footing or a change in floor level between the two rooms. It is levelled with screed or timber so one continuous floor finish, such as tiles or engineered boards, can run straight across.
  • 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.

Building control and neighbours in Gorseinon

In Wales, structural alterations come under the Building Regulations 2010 as they apply in Wales. Swansea Council handles building control for Gorseinon. 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 near Gorseinon

Kitchen-diner knock-throughs in Gorseinon: your questions

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

As a guide, budget £2,300–£5,450 including VAT for kitchen-diner knock-through in Gorseinon, based on published UK cost guides adjusted for prices in Wales (-9%). 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.

How soon can kitchen-diner knock-throughs start in Gorseinon?

Start dates depend on the engineer's calculations, the building control approval and, where needed, party wall notice periods. We give you a realistic timetable after the survey and keep you updated as each approval comes through.

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.

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.

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.

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

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.
