Main issues, as the Inspector framed them
- Whether the proposal would be inappropriate development in the Green Belt, including the effect on openness and purposes of the Green Belt, having regard to the National Planning Policy Framework and any relevant development plan policies
- The effect of the proposal on trees
- Whether any harm by reason of inappropriateness, and any other harm, would be clearly outweighed by other considerations, so as to amount to the very special circumstances required to justify the proposal
What decided it
The proposal fails to preserve the openness of the Green Belt and causes moderate harm to trees, with no other considerations of sufficient weight to constitute very special circumstances.
