Main issues, as the Inspector framed them
- The effect of the proposed development on the character and appearance of the surrounding area including whether the appeal scheme would conserve and enhance the Cornwall National Landscape
What decided it
The appeal site qualifies as rounding-off and infill development under Policy 3 of the Cornwall Local Plan, and the addition of one dwelling would not result in unacceptable harm to the character and appearance of the surrounding area or the conservation and enhancement of the Cornwall National Landscape.
The demonstrable housing need arising from the Council's inability to demonstrate a five-year housing land supply, combined with the site's qualification as rounding-off and infill development and the absence of unacceptable harm to landscape character and the National Landscape, outweighed any concerns regarding development in a sparsely settled area.
