Towns in Powys
Will the council need to approve it?
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.
Before any drawing is finalised we check whether the house is listed, in a conservation area or subject to an Article 4 direction.
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).
Covering Powys
Towns we cover in Powys include Newtown, Welshpool, Brecon, Llandrindod Wells. 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.

Porch extension questions answered
Can I see a price before committing to anything?
Yes. The guide prices on this page are adjusted for Powys, 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 Powys?
Yes, across the whole of Powys. Site visits are free and there is no obligation.
Will my neighbours in Powys 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.
