Main issues, as the Inspector framed them
- Whether the conversion of the existing dwelling to two self contained flats would be appropriate having regard to its location, relevant development plan policies and its effect on the residential character and appearance of the area
- The effect of the proposal on the living conditions of neighbouring occupiers and the future occupiers of the flats, with particular reference to noise and disturbance, light and outlook
What decided it
The proposal's compliance with Policy SC6 as a modest intensity conversion appropriate to the location, combined with the two-bedroom unit's effective functioning as family housing and the absence of harmful effects on character, appearance, or living conditions, outweighed the Council's concerns.
