Main issues, as the Inspector framed them
- whether the proposal would be 'inappropriate development', in terms of green belt policy
- the effects of the development on the character and appearance of the area
- any effects on living conditions at neighbouring properties
- any effects on highway safety
- any effects on trees
- any effects on ecology and biodiversity
- the weight to be given to the scheme's benefits
What decided it
The benefits of the scheme, uncertain in the absence of any legal obligation restricting occupation, did not clearly outweigh the substantial weight attributed to the permanent harm to the Green Belt.
The limited and uncertain benefits (health needs, self-build and specialist housing, and a contribution to general housing need) did not clearly outweigh the substantial weight attributed to the Green Belt harm, so the conflict with the development plan was not outweighed and the appeal was dismissed.
