Main issues, as the Inspector framed them
- whether or not the proposal is inappropriate development in the Green Belt
- the effect on the openness of the Green Belt
- the effect of the proposal on the character and appearance of the area including the Heronsgate Conservation Area
- if the development is inappropriate, its effect on openness and 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 proposal
What decided it
The substantial weight given to the moderate harm to Green Belt openness from the disproportionate extension was not clearly outweighed by any other considerations, and very special circumstances were not demonstrated.
What the Inspector cited
- Development plan policies
- CP11CP1CP12DM2DM1DM3

- Paragraph 137Paragraph 148Paragraph 199
