Main issues, as the Inspector framed them

  • The effects of the proposal, having particular regard to the external doors and Juliet balcony, upon the character and appearance of the area and upon the living conditions of neighbouring occupiers with regard to privacy

What decided it

The commonplace nature of L-shaped dormers with various door and balcony styles in the surrounding roofscapes, combined with the marginal proportional difference and the absence of additional external platform, meant the proposal would not harm character, appearance or neighbouring privacy.
