Main issues, as the Inspector framed them
- whether the proposal would be inappropriate development in the Green Belt
- the effect upon the openness of the Green Belt
- if the development is inappropriate, whether the harm by reason of inappropriateness, and any other harm, is clearly outweighed by other considerations so as to amount to the very special circumstances necessary to justify development
What decided it
The cumulative 30% increase in footprint, combined with the subordinate roof design, falls below the 40% threshold for disproportionate additions and therefore qualifies as a permitted exception to inappropriate development in the Green Belt.
What the Inspector cited
- Development plan policies
- Policy CP11Policy DM2
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.
