Main issues, as the Inspector framed them
- whether the proposal would be inappropriate development in the Green Belt for the purposes of the development plan and the National Planning Policy Framework (2021)
- the effect of the proposal on the openness of the Green Belt
- the effect of the proposal on the character and appearance of the host dwelling, and the surrounding area
- if the proposal would be inappropriate development, 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 it
What decided it
The proposal would result in disproportionate additions to the original building in breach of NPPF paragraph 149, constituting inappropriate development in the Green Belt for which no very special circumstances exist to justify approval.
