  • Single-storey rear extensions do not extend beyond the rear wall by more than 3 meters for connected homes, or 4 meters for detached houses (though larger limitations approximately 6m/8m may apply through the Prior Approval procedure).
  • The materials are of a similar look to the existing house.
