Main issues, as the Inspector framed them
- Whether the proposal would be inappropriate development in the Green Belt, having regard to the Development Plan and the National Planning Policy Framework and the effect of the proposal on the openness of the Green Belt
- If the proposal would be 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 necessary to justify it
What decided it
The fallback position of the previously granted Certificate of Lawfulness for substantially larger and more visually harmful works constituted a very special circumstance of significant weight that clearly outweighed the harm to the Green Belt.
The harm to the Green Belt by reason of inappropriateness was clearly outweighed by the very special circumstance that the fallback Certificate of Lawfulness scheme would result in greater harm to openness and character, making the proposed smaller and more considered alternative the preferable outcome.
