Main issues, as the Inspector framed them
- Whether or not 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 development, when considered cumulatively with previous extensions to the property, would constitute inappropriate development in the Green Belt causing substantial harm that is not clearly outweighed by other considerations, and therefore very special circumstances do not exist to justify approval.
