Main issues, as the Inspector framed them
- The effect of the proposal on biodiversity at the site
- The effect of the proposal on the character and appearance of the area
- The effect of the proposal on the living conditions of neighbouring residential occupiers at No. 10a Rydal Gardens and No. 16 Rydal Gardens with particular regard to any overlooking of private amenity spaces and at No. 10a with regard to any loss of light
- Whether there would be any unacceptable impact on highway and pedestrian safety with particular regard to the proposed new crossover
What decided it
The failure to undertake required bat surveys and the substantial net loss of biodiversity (-37.04%) with no clear mitigation proposals conflicted with development plan policy and could not be outweighed by the housing benefits.
