Main issues, as the Inspector framed them

Whether the proposal would be inappropriate development in the Green Belt
Its effect on the openness of the Green Belt
Its effect on the character and appearance of the area with specific regard to a Non Designated Heritage Asset, the Pinnerwood Farm Conservation Area and the setting of a grade II listed building
If the scheme would be inappropriate development, 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 would constitute inappropriate development in the Green Belt with disproportionate additions that would unacceptably reduce openness and cause substantial harm to heritage assets, with no very special circumstances demonstrated to justify the scheme.
