Do I need planning permission in Dyfed?
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.
The planning position for a specific Dyfed address depends on its history and any designations, which is why we check it at the first visit.
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).
