Main issues, as the Inspector framed them
- the effect of the proposed development on the character and appearance of the appeal property and the wider area
- whether it would provide satisfactory living conditions for the future occupiers of both flats, with respect to single bedroom private internal space
- its effect on the living conditions of the existing occupier of 35A Coldharbour Lane, having regard to outlook and daylight
What decided it
The cumulative effect of significant harm to character and appearance, failure to meet space standards for future occupiers, and unacceptable impact on neighbouring amenity through loss of outlook and daylight could not be outweighed by the limited benefits of one additional dwelling.
The modest benefits of providing one additional home and encouraging local regeneration were insufficient to outweigh the significant harm identified across all three main issues.
