Main issues, as the Inspector framed them
- the effect of the proposal on the setting of the Grade II listed 'Rat's Castle Cottage'
- whether or not the proposal would be inappropriate development in the Green Belt having regard to the Framework and relevant development plan policies
What decided it
The identified less than substantial harm to the setting and significance of the Grade II listed building, to which great weight must be attached under paragraph 212 of the Framework, outweighs the public benefits of the proposal and provides a strong reason for refusal under paragraph 11(d)(i).
The modest benefits of housing delivery, sustainable design measures, economic benefits and efficient use of land were outweighed by the less than substantial harm to the setting of the Grade II listed building, to which great weight must be attached; the heritage balance fell against the scheme and the presumption in favour of development did not apply.
