Main issues, as the Inspector framed them
- Whether the proposal would be inappropriate development in the Green Belt having regard to the National Planning Policy Framework 2023 and any relevant development plan policies
- The effect of the proposal on the openness of the Green Belt
- Whether any harm by reason of inappropriateness, and any other harm, would be clearly outweighed by other considerations, so as to amount to the very special circumstances required to justify the proposal
What decided it
The proposed extension results in a disproportionate addition to the original dwelling (approximately 62% increase in floorspace when combined with previous extensions), causing substantial harm to the Green Belt's openness and inappropriateness, which is not outweighed by the minor benefits claimed.
What the Inspector cited
- Development plan policies
- Policy GB1 of the Allocations and Development Management Plan (2015)
- National Planning Policy Framework
- Paragraph 153Paragraph 154Paragraph 155
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.
