Main issues, as the Inspector framed them
- the effect of the proposed development on the character and appearance of the area
- the effect of the proposed parking arrangement on highway safety
- whether the proposal would make adequate provision for Biodiversity Net Gain (BNG)
- the effect of the proposed development on protected species
What decided it
The unacceptable effect on the character and appearance of the area, which would conflict with NPPF paragraph 135 and WDLP Policies CP9 and DM35, was given significant weight that demonstrably outweighed the moderate benefits of delivering a single dwelling in a location with housing land supply shortfall.
The adverse impacts of unacceptable harm to character and appearance (significant weight) significantly and demonstrably outweighed the benefits of housing delivery and efficient use of land (moderate weight), such that the presumption in favour of sustainable development under NPPF paragraph 11(d) did not apply.
