Main issues, as the Inspector framed them
- whether the proposal would be inappropriate development in the Green Belt and the effect of the proposal on openness
- the effect of the proposed development on protected species
- whether the 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 detached garage structure constitutes inappropriate development in the Green Belt causing moderate harm to openness, and the personal circumstances and equality considerations, whilst given considerable weight, do not clearly outweigh the substantial weight that must be attached to Green Belt harm.
What the Inspector cited
- Development plan policies
- Policy QP5Policy NR2
- National Planning Policy Framework
- Paragraph 154
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.
