Main issues, as the Inspector framed them

whether the proposed development is inappropriate development in the Green Belt having regard to the National Planning Policy Framework and relevant development plan policies, including the effect on the openness and purposes 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 very special circumstances required to justify the appeal scheme

What decided it

The proposal is inappropriate development in the Green Belt that fails to meet any exception and lacks very special circumstances to justify it, as the other considerations do not clearly outweigh the harm to openness.
