Main issues, as the Inspector framed them

• Whether the proposal would be inappropriate development in the Green Belt having regard to the National Planning Policy Framework and any relevant development plan policies
• The effect of the proposal on the openness of the Green Belt
• The effect of the proposed development on flood risk
• The effect of the proposed development on ecology
• If the development would be inappropriate, whether the harm to the Green Belt by way 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 it

What decided it

The cumulative effect of the proposed extension and previous extensions would result in a disproportionate addition of approximately 145% in footprint over the original building, constituting inappropriate development in the Green Belt that cannot be justified by very special circumstances.

The substantial harm to the Green Belt by way of inappropriateness and minor harm to openness, together with flood risk harm, were not clearly outweighed by the limited private benefit to the appellant, resulting in no very special circumstances to justify the development.
