Main issues, as the Inspector framed them
- Whether the condition removing permitted development rights under the GPDO is reasonable and necessary to safeguard the openness of the Green Belt
What decided it
The cumulative increase in volume from previous extensions (123% over the original dwelling) substantially exceeded the 50% threshold in Policy GB1, making the proposal inappropriate development that could only be justified by very special circumstances, which required the removal of permitted development rights to protect Green Belt openness.
What the Inspector cited
- Development plan policies
- Policy GB1 of the Sevenoaks Allocations and Development Management Plan 2015
- 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.
