Main issues, as the Inspector framed them

Whether the proposal would be inappropriate development in the Green Belt having regard to any relevant development plan policies and the National Planning Policy Framework
The effect of the proposed development on the openness of the Green Belt
The effect of the proposed development on trees

What decided it

The cumulative visible increase in the footprint and volume of the building beyond 25%, particularly through the exposure of the basement as a lower ground floor storey via the sunken patio, constitutes disproportionate additions contrary to Policy DM18 and Framework Paragraph 154.c), and the resulting harm to Green Belt openness cannot be outweighed by other considerations.
