Main issues, as the Inspector framed them
- whether the proposal constitutes inappropriate development in the Green Belt having regard to the National Planning Policy Framework 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 would constitute a disproportionate addition to the original building and cause substantial harm to Green Belt openness, which was not clearly outweighed by other considerations.
What the Inspector cited
- Development plan policies
- Policy CP3
- National Planning Policy Framework
- Paragraph 154Paragraph 153
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.
