Main issues, as the Inspector framed them
- Whether the proposal would be inappropriate development in the Green Belt, having regard to the Framework and relevant policies of the Development Plan
- 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, would be clearly outweighed by other considerations so as to amount to the very special circumstances required to justify it
What decided it
The cumulative floor space increase of over 75% represents a disproportionate addition to the original building that is harmful to the Green Belt by definition, and no other considerations clearly outweigh this harm to justify very special circumstances.
The substantial harm to the Green Belt by reason of inappropriateness and loss of openness was not clearly outweighed by other considerations including design quality, removal of the garage, or private household benefits, and very special circumstances do not exist.
