Do you need planning permission for a wraparound extension in Pontypool?
Approvals for a wraparound extension in Pontypool follow the rules for Wales. In Wales a wraparound extension combines side and rear elements; it can only be permitted development if each part meets the limits, so many need a householder planning application.
Building regulations in Wales are set by the Welsh Government. Approval comes from the council’s building control service or a registered building control approver, with inspections during the work and a completion certificate at the end.
At the survey we check your house’s planning history and any restrictions, and tell you which route applies.

Questions about wraparound extensions in Pontypool
What about the old back addition?
The side wall of the back addition is usually removed and replaced with a steel beam, so the old kitchen joins the new space.
Is a wraparound worth it?
It gives the biggest ground-floor space without going upwards. Whether it adds value depends on your street and house, so we suggest checking local sale prices before committing.
Can we keep a separate living room?
Yes. Many clients keep the front room separate and open up only the back of the house.
