Main issues, as the Inspector framed them

  • The effect of the proposed development on European Protected Species
  • Whether the proposed development would satisfy the requirements of the statutory framework for biodiversity net gain
  • Whether the proposed development would provide a satisfactory standard of accommodation with regard to access to outdoor amenity space
  • The effect of the proposed development on the living conditions of the occupants of the neighbouring property at No 15 Dollis Park with particular reference to outlook
  • The effect of the proposed development on the character and appearance of the site and the surrounding area

What decided it

The failure to provide a preliminary roost appraisal for European Protected Species, combined with unresolved biodiversity net gain requirements and the lack of outdoor amenity space for one flat, meant the proposal could not be approved despite a fallback position for the external works.
