Main issues, as the Inspector framed them
- the effect of the hardstanding on the setting of designated heritage assets
- whether the hardstanding is inappropriate development in the Green Belt
- the effect of the hardstanding on the openness of the Green Belt
- would the harm by reason of inappropriateness, and any other harm, be clearly outweighed by other considerations. If so, would this amount to the very special circumstances required to justify the proposal?
What decided it
The Inspector found that the substantial harm to Green Belt openness, combined with less-than-substantial but weighty harm to the setting of the listed buildings, was not clearly outweighed by the appellant's other considerations, so very special circumstances did not exist and the deemed planning application failed.
the substantial harm to Green Belt openness (given substantial weight) and the less-than-substantial harm to the setting of the listed buildings (given great weight) were not clearly outweighed by the appellant's considerations in support of the hardstanding (given very limited to moderate weight), so very special circumstances did not exist and the balance tipped against the development
