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 relevant development plan policies, including any relevant effects on the openness of the Green Belt
Whether the 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 harm to the Green Belt by reason of inappropriateness and significant loss of openness is not clearly outweighed by other considerations, and therefore very special circumstances do not exist to justify the development.

What the Inspector cited

Development plan policies: Policy MG02
National Planning Policy Framework: Paragraph 153Paragraph 154
