Planning and approvals in Swansea
In Wales small porches are usually permitted development within size and boundary limits similar to England's. We check the current Welsh limits for your address.
Homes in conservation areas, national parks, National Landscapes (AONBs) and World Heritage Sites have tighter rules, so we always check the property's status and planning history before design starts.
The Party Wall etc. Act 1996 applies in Wales as in England: notice must be served before work to a shared wall, building on the boundary, or excavating close to a neighbour's foundations.
Applications are decided by the local planning authority (your county or county borough council, or the national park authority).
Covering Swansea
Postcode districts we cover around Swansea include SA1, SA2, SA3, SA5, SA6, SA7. Nearby, we also take on projects in Clydach (5 miles), Briton Ferry (5 miles), Gorseinon (5 miles), Neath (7 miles).
For homes towards Dyfed, Llanelli is around 10 miles away. 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.
From first visit to completion
Site visits are free and there is no obligation. Where drawings are needed, the design stage is priced in writing before it starts.

We visit your Swansea home, measure up, talk through what you want and check the planning position.
Design and approvals
We produce the drawings and structural design, and manage the approvals so they are in place before work starts.
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
Our team builds the extension, keeps you updated weekly and finishes with building control sign-off.
Porch extension questions answered
Can I see a price before committing to anything?
Yes. The guide prices on this page are adjusted for Swansea, and the guide-price tool gives a range for your own size. After the survey you get a written price before anything is agreed.
How long does a porch extension take to build in Swansea?
On site, typically 2 to 4 weeks once approvals are in place. Before that, allow 2–8 weeks design and approvals.
Will my neighbours in Swansea be involved?
If a planning application is needed, the council notifies neighbours. If the work is on or near a shared boundary, party wall notices may also be needed.
How much does a porch cost?
Our guide range is about £3,700 to £13,950 including VAT, depending on size, materials and whether it includes a WC.
