Main issues, as the Inspector framed them

  • Whether the proposal would be inappropriate development in the Green Belt
  • Its effect on the openness of the Green Belt
  • If the scheme is inappropriate development, whether the harm by reason of inappropriateness, and any other harm, is clearly outweighed by other considerations, as to amount to very special circumstances required to justify it

What decided it

The proposal constitutes inappropriate development in the Green Belt that would reduce openness both spatially and visually, and the modest benefits claimed do not clearly outweigh this substantial harm to justify very special circumstances.
