How is a garden annexe approved in Newport, Gwent?
In Wales the planning rules, including what counts as permitted development, are set by the Welsh Government, and Welsh building regulations differ in places from England’s. We check both against your house before drawings are finalised, and handle party wall notices where needed.
In Wales an annexe with sleeping accommodation needs planning permission, usually with a condition tying it to the main house.
