Main issues, as the Inspector framed them

whether the proposed extension would be inappropriate development in the Green Belt having regard to the development plan and the National Planning Policy Framework including the effect on the openness of the Green Belt
if the development is inappropriate, whether the harm, by reason of inappropriateness, and any other harm, would clearly be outweighed by other considerations, so as to amount to the very special circumstances required to justify the development

What decided it

The cumulative effect of the proposed extension combined with previous extensions would result in a disproportionate addition to the original building (198% increase in floorspace), failing to meet the exception in NPPF paragraph 154(c) and constituting inappropriate development in the Green Belt that is not justified by very special circumstances.
