Why it was refused

  1. Due to a lack of information, the scheme has failed to demonstrate that the proposed conversion of teh ground floor unit to residential use would not have a negative impact upon the vitality and viability of the Blackbird Hill Neighbourhood Parade, contrary to Policy DMP1 & BE6 of the Brent Local Plan (2019-2041).
  2. The access to the proposed flat is from an unlit alleyway/service road with poor natural surveillance, increasing the likely opportunity for crime, and failing to meet the Council’s safety and design standards, contrary to DMP1 of the Brent Local Plan (2019-2041) and Supplementary Planning Document 1 – Brent Design Guide (2018).
  3. The proposed development, as a result of not providing any defensible space, would result in poor quality accommodation for occupiers of the flat, due to the location of the front bedroom windows on the frontage of the neighbourhood parade and their proximity to the pedestrian crossing, resulting in significant noise disturbance and privacy concerns, contrary to DMP1 of the Brent Local Plan (2019-2041) and D6 of London Plan (2021).
  4. The proposed development, by reason of its design would be out of keeping and character with the remainder of the neighbourhood parade of which it is a part and introduce a harmful break in the continuity of frontages, resulting in an unduly detrimental impact on the streetscene and character of the area, contrary to DMP1 & BD1 of the Brent’s Local Plan (2019-2041) and Supplementary Planning Document 3 – Shopfronts (2018).
  5. The proposal would result in an overprovision of off-street parking, encouraging excessive reliance on private motor vehicles, which in turn would fail to maximise sustainable modes of transport and would encourage unnecessary car use and ownership in the area, adding to traffic congestion and contributing to climate change, contrary to Policy DMP1, BT1 and BT2 of Brent's Local Plan (2019-2041).
  6. In the absence of submissions addressing fire safety, the proposed development would not demonstrably address the need for fire risk mitigation. The proposal is therefore unacceptable and contrary to the requirements of policy D12 of the London Plan (2021).

From the council's decision notice.
