Main issues, as the Inspector framed them

  • Whether the matters alleged in the enforcement notice constitute a breach of planning control (ground c)
  • Whether the requirements of the enforcement notice exceed what is necessary to remedy the breach (ground f)
  • Whether the period for compliance with the enforcement notice is reasonable (ground g)

What decided it

The appellant failed to demonstrate on the balance of probabilities that the outbuilding was erected before the extension, and therefore the development in its entirety constitutes a breach of planning control that must be remedied by demolition.
