Main issues, as the Inspector framed them
- Whether the proposal would be inappropriate development in the Green Belt having regard to the revised National Planning Policy Framework and any relevant development plan policies
- The effect 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 cumulative disproportionality of extensions (111% increase over original dwelling) constitutes inappropriate development in the Green Belt, and the private benefits advanced do not amount to very special circumstances to outweigh the substantial weight given to Green Belt harm.
What the Inspector cited
- Development plan policies
- Policy R4 of the Trafford Core Strategy 2012
- 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.
