Main issues, as the Inspector framed them

  • The effect of the proposal on the character and appearance of the host dwelling and its surroundings

What decided it

The permitted development status of the dormer, combined with the visual coherence provided by the reduced-width two-storey extension with gabled roof design, meant the cumulative effect would not cause unacceptable harm to character and appearance.
