Main issues, as the Inspector framed them
- whether the development would provide its occupants with acceptable living conditions, with regard to internal space
- the effect of the proposal on the living conditions of neighbouring occupiers, in particular the occupiers of 35 Longfield Avenue, having regard to noise and disturbance
What decided it
The proposal would not result in material harm to neighbouring living conditions or unacceptable conditions for future occupants, and the minor conflict with Policy 10 regarding the semi-detached nature of the property was outweighed by the material consideration of providing housing for two additional individuals.
What the Inspector cited
- Development plan policies
- Policy 10Policy 29London Plan Policy D12
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.
