Main issues, as the Inspector framed them
- Whether the proposed extension is inappropriate development within the Green Belt including openness
- If the proposal is inappropriate development within the Green Belt, whether the harm by reason of inappropriateness, and any other harm, is clearly outweighed by other considerations so as to amount to very special circumstances to justify development
What decided it
The rear extension exceeds the 50% disproportionality threshold and constitutes inappropriate development within the Green Belt, and the collective Green Belt harm is not clearly outweighed by other considerations so as to amount to very special circumstances.
The substantial harm from inappropriate development in the Green Belt was not outweighed by the limited weight afforded to the fallback position, health circumstances, housing land supply shortfall, and other considerations, resulting in dismissal.
What the Inspector cited
- Development plan policies
- Policy HS5 of the Chorley Local Plan 2015
- National Planning Policy Framework
- Paragraph 152Paragraph 154Paragraph 11
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.
