Main issues, as the Inspector framed them

Whether the proposal would be inappropriate development in the Green Belt having regard to the National Planning Policy Framework and any relevant development plan policies
The effect of the proposal on the openness of the Green Belt
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 constitutes inappropriate development in the Green Belt causing substantial harm to openness, and the other considerations advanced do not clearly outweigh this harm to justify very special circumstances.
