Covering Gwent
Towns we cover in Gwent include Newport, Gwent, Cwmbran, Pontypool, Ebbw Vale, Abergavenny, Monmouth, Chepstow. Welsh housing ranges from stone terraces in the valleys to render-and-slate houses and modern estates, and the Welsh planning rules differ from England's in several places.
Do I need planning permission in Gwent?
In Wales a single-storey rear extension can usually project up to 4 m beyond the rear wall without a planning application, if it is no more than 4 m high, keeps eaves to 3 m and overall height to 4 m within 2 m of a boundary, and covers no more than half the land around the original house. Wales has no larger home extension prior approval scheme.
In a conservation area, national park, National Landscape or World Heritage Site the permitted development limits are tighter (no side or two-storey extensions without an application). Listed homes need listed building consent, and if permitted development rights have been removed, any extension needs an application.
Building over or within 3 m of a public sewer needs the water company's consent before the foundations go in.
Building regulations approval is separate from planning. Wales has its own building regulations and approved documents; the council or a registered building control approver checks the plans, inspects the work and issues a completion certificate.
Applications are decided by the local planning authority (your county or county borough council, or the national park authority).

How the project works
Site visits are free and there is no obligation. Where drawings are needed, the design stage is priced in writing before it starts.
Free site visit
First, a site visit: we look at the house, garden, access and drains and listen to what you need.
Design and approvals
Once the layout is agreed, we deal with the council: planning permission or written confirmation that none is needed, plus building control.
Fixed written price
We confirm the build price in writing, based on the approved drawings and the finishes you have chosen.
Build and sign-off
We build it with one project manager, book the building control inspections and hand over the completion certificate.
Kitchen extension questions answered
Can I see a price before committing to anything?
Yes. The guide prices on this page are adjusted for Gwent, and the guide-price tool gives a range for your own size. After the survey you get a written price before anything is agreed.
Do you cover all of Gwent?
Yes, across the whole of Gwent. Site visits are free and there is no obligation.
Who do I contract with for a kitchen extension in Gwent?
Your contract is with S&K Property Investments and Improvement Ltd, which designs and manages the project and the build teams who carry it out.
Can you fit a kitchen I buy elsewhere?
Yes. We can fit it or work with your supplier’s fitters. We need the layout early so that drains, services and lighting are in the right place.
How much does a kitchen extension cost?
For the extension itself our guide range is about £1,670 to £3,260 per m² including VAT. A standard 20 m² kitchen extension is typically around £39,000 to £49,500 in Gwent, plus the kitchen itself, which commonly adds £9,000 to £20,000 for a mid-range design.
