Main issues, as the Inspector framed them

The effect of the proposal on the openness of the Green Belt
The effect of the proposal on the character and appearance of the area around Hawkshead Lane
If inappropriate, would the harm by reason of inappropriateness, and any other harm, be clearly outweighed by other considerations so as to amount to the very special circumstances required to justify the proposal

What decided it
