Main issues, as the Inspector framed them
- The effect of the proposal on the character and appearance of the area
- The effect of the proposal on the living conditions of occupiers of neighbouring properties, with particular regard to privacy, noise and disturbance
What decided it
The substantial harm to the character and appearance of the area, resulting from the unduly bulky dormer and incongruous terrace walls that would interrupt the uniform roofscape and homogeneity of the building group, outweighed the absence of harm to neighbouring amenity.
The absence of harm to the amenity of neighbouring residents would not outweigh the significant harm to the character and appearance of the area.
