Main issues, as the Inspector framed them
- Whether the proposed development would amount to inappropriate development in the Green Belt, having regard to the NPPF 2024 and any relevant development plan policies
- The effect on the openness of the Green Belt
- If the proposed development would amount to inappropriate development, whether the harm by reason of inappropriateness and any other harm is clearly outweighed by other considerations, such as to amount to the very special circumstances necessary to justify the development
What decided it
The cumulative increase in floor area of 132% above the original cottage constitutes disproportionate additions that cannot be justified by the absence of other planning harms or the modest fallback position of a 3m permitted development extension.
