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 and any relevant development plan policies
- The effects 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 existence of a realistic fallback position (Certificate of Lawful Development for single-storey extensions) that would cause greater harm to Green Belt openness than the appeal proposal amounts to very special circumstances justifying the inappropriate development.
What the Inspector cited
- Development plan policies
- Policy GB1
- National Planning Policy Framework
- Paragraph 137Paragraph 147Paragraph 148Paragraph 149Paragraph 54
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.
