Welsh projects need planning clearance from the council under Welsh rules, building regulations approval under the Welsh approved documents, and party wall notices where the work affects a neighbour’s wall or foundations.
In Wales an annexe with sleeping accommodation needs planning permission, usually with a condition tying it to the main house.
