Main issues, as the Inspector framed them

  • Whether sufficient information has been provided to demonstrate that the proposed basement development would not have unacceptable impacts, including in respect of the ground water environment and land stability (including the structural integrity of neighbouring properties)
  • Whether the development would provide acceptable living conditions for future occupiers, with regard to outlook, daylight, amenity space, and privacy and overlooking
  • The effect of the proposed development on demand for on-street parking
  • Whether the development would adequately promote and support the use of sustainable means of travel

What decided it

The absence of a Basement Impact Assessment to demonstrate the proposed basement development would not cause unacceptable harm to neighbouring structures, groundwater and land stability, combined with inadequate living conditions for future occupiers and failure to secure sustainable travel measures through a planning obligation, meant the proposal conflicted fundamentally with the development plan with no material considerations to outweigh this.
