Main issues, as the Inspector framed them
- whether or not the proposal is inappropriate development in the Green Belt
- the effect on the openness of the Green Belt
- if the development is inappropriate, its effect on openness and 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 required to justify the proposal
What decided it
The proposal would be inappropriate development causing substantial harm to Green Belt openness, and the limited design benefits do not amount to very special circumstances necessary to justify the development.
What the Inspector cited
- Development plan policies
- Policy CP11Policy DM2
- National Planning Policy Framework
- Paragraph 137Paragraph 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.
