Main issues, as the Inspector framed them
- whether or not the proposal would be inappropriate development within the Green Belt having regard to the Framework and any relevant development plan policies
- the effect of the proposal on the openness of the Green Belt
- the effect of the proposal on the living conditions of the occupiers of Brackens, with particular reference to outlook and light
- the effect of the proposal on the character and appearance of the host dwelling
- if the proposal would be inappropriate development, whether or not 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 necessary to justify the proposal
What decided it
The proposal constitutes inappropriate development in the Green Belt that is not clearly outweighed by other considerations, and therefore very special circumstances do not exist to justify approval.
The substantial harm to the Green Belt by reason of inappropriateness and harm to openness, combined with harm to the living conditions of neighbouring occupiers, was not clearly outweighed by the limited benefit of improved living conditions for the appellant's household.
