Main issues, as the Inspector framed them
- The effect of the proposed extension on the living conditions of occupants at No.19 Derwent Road, with particular regard to overshadowing and loss of light
What decided it
The proposed extension would cause significant harm to the living conditions of the neighbouring occupier through substantial overshadowing and loss of light, which could not be outweighed by the appellant's personal circumstances or the absence of neighbour objections.
The personal circumstances and health benefits to the appellant were weighed against the significant harm to neighbouring living conditions through overshadowing and loss of light; the harm to the neighbour's amenity outweighed the appellant's personal circumstances.
What the Inspector cited
- Development plan policies
- Policy DM29 of A Local Plan for Lancaster District 2011-2031 Part Two: Review of the Development Management DPD, 2020
- National Planning Policy Framework
- Paragraph 12
How the Inspector dealt with each one is set out in the app, in order: the development plan, national policy, housing land supply, other considerations and the planning balance, beside the letter.
