Main issues, as the Inspector framed them

  • whether the proposed development would be in a suitable location having regard to local policies on employment uses
  • whether the proposed development would provide adequate refuse and recycling facilities
  • whether the proposed development would provide satisfactory living conditions for future residents with regard to the provision of adequate internal spaces
  • whether the proposed development would ensure adequate levels of internal water usage

What decided it

The failure to demonstrate through rigorous marketing that the office space was surplus to employment needs, combined with the considerable policy conflict with employment protection policies, substantially outweighed the benefits of providing one additional dwelling in a location with a housing land supply shortfall.

applying Policy S4, the substantial benefits of providing one additional dwelling in a sustainable location and contributing to the housing land supply shortfall were substantially outweighed by the considerable harm to the vitality, viability and employment growth of the Surbiton District Centre.
