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 relevant development plan policies
The effect of the proposed development on the openness of the Green Belt
If the proposed development is inappropriate development, whether the harm by reason of inappropriateness, and any other harm, is clearly outweighed by other considerations so as to amount to the very special circumstances required to justify the proposed development

What decided it

The volume increase of less than 50% of the existing dwelling, combined with the appropriate pitched roof design reducing visual bulk and mass, meant the proposal did not result in a disproportionate addition and thus fell within the NPPF paragraph 154(c) exception for extensions in the Green Belt.

What the Inspector cited

Development plan policies: Policy M12
National Planning Policy Framework: Paragraph 154
