What kitchen-diner knock-throughs involve in Porthmadog
Need kitchen-diner knock-throughs in Porthmadog? Our coverage runs across Gwynedd, so nearby villages are included too. We survey the property, arrange the engineer's design, deal with Cyngor Gwynedd, fit the steel and make good, all under one quote for LL47, LL48 and LL49 addresses.
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
- If the kitchen also opens onto the hallway, the change can affect the escape route from the bedrooms. Building control checks how people would get out in a fire, and smoke alarms, a fire door or other measures may be required as part of approval.
- 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.
- 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.
- 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.
- 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.
How the job runs in Porthmadog
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.
Design and price
Calculations come back from the engineer and we confirm your fixed written price, line by line.
Building control
We submit the application or notice to Cyngor Gwynedd under the Building Regulations as they apply in Wales, before work starts.
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 rules for Porthmadog
Welsh building regulations treat beams and new openings as controlled building work. We apply to Cyngor Gwynedd on your behalf before anything is removed, give the commencement notice the 2026 Welsh rules require, and the steel is checked before it is boxed in.
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.

Questions about kitchen-diner knock-throughs in Porthmadog
How much do kitchen-diner knock-throughs cost in Porthmadog?
As a guide, budget £2,300–£5,450 including VAT for kitchen-diner knock-through in Porthmadog, 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.
Do you cover Porthmadog for kitchen-diner knock-throughs?
Yes. We carry out kitchen-diner knock-throughs in Porthmadog and the LL47, LL48 and LL49 postcode districts. Book a free survey visit and we will check the wall, arrange the engineer's calculations and send an itemised written quote.
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 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.
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 I stay at home while the work is done in Porthmadog?
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.
