Main issues, as the Inspector framed them

  • whether the scheme would be inappropriate development in the Green Belt having regard to any relevant development plan policies and the National Planning Policy Framework
  • the effect of the development on the openness of the Green Belt
  • whether the harm by reason of inappropriateness would be clearly outweighed by other considerations, so as to amount to the very special circumstances necessary to justify it

What decided it

The proposed extension would constitute disproportionate development in the Green Belt with no very special circumstances to justify it, as the harm to openness and inappropriateness was not clearly outweighed by other considerations.
