Main issues, as the Inspector framed them
- Whether the proposed development would be inappropriate development in the Green Belt, including the effect on the openness of the Green Belt
- The effect of the proposed development on the character and appearance of the existing site and of the local area
- If the development is inappropriate, whether the harm, by reason of inappropriateness, and any other harm, is clearly outweighed by other considerations, and if so, whether this would amount to the very special circumstances necessary to justify the proposal
What decided it
The proposal constitutes inappropriate development in the Green Belt as a disproportionate addition to the original building, and the harm to the Green Belt is not outweighed by other material considerations.
