Planning and approvals in Welshpool
In Wales a wraparound must satisfy both the rear and side extension limits to be permitted development, so most need a planning application to the council.
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.
Building over or within 3 m of a public sewer needs the water company's consent before the foundations go in.
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).

When a wraparound extension makes sense
- Terraced houses that want the largest ground floor possible
- Semi-detached houses with a side passage
- Families who want kitchen, dining and living in one space
The corner is where wraparounds succeed or fail. We usually use a single steel goalpost or a corner post hidden in a pier, and set the glazing so the new room reads as one space rather than two boxes.

Common questions in Welshpool
Can I see a price before committing to anything?
Yes. The guide prices on this page are adjusted for Welshpool, 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 I need building regulations approval in Welshpool?
Yes. Almost every extension needs it, whatever the planning route. We prepare the drawings and book the inspections.
How long does a wraparound extension take to build in Welshpool?
On site, typically 14 to 20 weeks once approvals are in place. Before that, allow 8–16 weeks design and approvals.
How much does a wraparound extension cost?
Our guide range is about £1,860 to £3,440 per m² including VAT. A 25 m² standard-spec wraparound typically lands around £53,000 to £67,500 in Welshpool before design and council fees.
Is a wraparound better than a side return alone?
It adds far more space, but costs more and needs planning permission more often. Our comparison guide sets the two side by side.
