Main issues, as the Inspector framed them

  • Whether the outbuilding and boundary treatment constitute permitted development under Schedule 2 Part 1 Class E and Schedule 2 Part 2 Class A of the GPDO
  • Whether the requirements of the enforcement notice exceed what is necessary to remedy the breach of planning control

What decided it

Both the outbuilding and boundary treatment failed to qualify as permitted development under the GPDO and therefore constituted breaches of planning control that the enforcement notice properly requires to be remedied by removal.
