Main issues, as the Inspector framed them
- Whether the proposed development 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 proposed development on the openness of the Green Belt
- If the proposed development is inappropriate development, whether the harm by reason of inappropriateness, and any other harm, is clearly outweighed by other considerations so as to amount to the very special circumstances required to justify the proposed development
What decided it
The proposed extensions would result in disproportionate additions to the original building exceeding the 50% increase threshold, constituting inappropriate Green Belt development whose substantial harm is not clearly outweighed by the other considerations advanced.
