Main issues, as the Inspector framed them
- whether the proposed extension would be inappropriate development in the Green Belt having regard to the National Planning Policy Framework and any relevant development plan policies
- the effect of the proposed development on the openness of the Green Belt
- whether other considerations clearly outweigh the harm to the Green Belt, and any other harm, so as to amount to very special circumstances
What decided it
The proposed extension would result in a disproportionate 95.7% increase in floor space, constituting inappropriate development in the Green Belt with no demonstrated very special circumstances to justify it.
What the Inspector cited
- Development plan policies
- Policy GB1
- National Planning Policy Framework
- Paragraph 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.
