Main issues, as the Inspector framed them

  • The effect of the proposal on the character and appearance of the surrounding area
  • The effect of the proposal on the living conditions of the occupiers of Sunnyside with particular regard to visual impact

What decided it

The proposed extensions would unacceptably harm the character and appearance of the surrounding area and cause material harm to the living conditions of the occupiers of Sunnyside through overbearing visual impact, conflicting with development plan policies and the Framework.

The benefits to the appellants from enlarged first floor accommodation and balcony were clearly outweighed by the material harm to character and appearance of the host dwelling and surrounding area.
