Main issues, as the Inspector framed them
- Whether the disputed condition 2 is reasonable and necessary having regard to whether the development is inappropriate development in the Green Belt
- The effect of the development on the openness of the Green Belt
- If it 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 necessary to justify the development
What decided it
The garage and rooflights represent a very small addition that does not result in disproportionate additions over and above the size of the original building, and therefore the development is not inappropriate development in the Green Belt.
What the Inspector cited
- Development plan policies
- Policy MG02Policy BE14
- National Planning Policy Framework
- Paragraph 149
How the Inspector dealt with each one is set out in the app, in order: the development plan, national policy, housing land supply, other considerations and the planning balance, beside the letter.
