Main issues, as the Inspector framed them
- Whether or not the proposal is inappropriate development in the Green Belt
- The effect of the proposal on the openness of the Green Belt
- If the proposal is 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 the development
What decided it
The proposal would constitute inappropriate development in the Green Belt resulting in disproportionate additions and a loss of openness, and the other considerations advanced did not clearly outweigh this harm to amount to very special circumstances.
The substantial harm to the Green Belt by reason of inappropriateness and loss of openness was not outweighed by the appellant's desire for improved accommodation, the relative scale of neighbouring properties, or the potential for permitted development, such that very special circumstances do not exist.
