Why it was refused

  1. The proposal is not located within a priority area for new housing and is not in an area with good access to public transport and other amenities, resulting in higher levels of car dependency, contrary to policies DMP1, BH10 and BH7 of the Brent Local Plan (2019-2041).
  2. The management plan submitted with the application is insufficient as it does not demonstrate arrangements to meet a specific Brent need, contrary to policy BH7 of the Brent Local Plan (2019-2041).
  3. The proposed development would result in the loss of a larger family-sized residential unit, for which there is an identified need in the borough and the applicant has not demonstrated a specific Brent need for a Children’s Home (Use Class C2) contrary to Policies BH10 and BH7 of the Brent Local Plan (2019-2041).
  4. The proposal, due to inaccurate plans in relation to the front garden arrangement and the internal layout, cannot be accurately assessed. Furthermore, the proposed development would result in insufficient soft landscaping provision within the frontage, to the detriment to the character of visual amenity and natural drainage, contrary to Policies DMP1 and BT2 of the Brent Local Plan (2019-2041), to the Domestic Footway Vehicle Crossover Policy (2018) and to the Mount Stewart Conservation Area Design Guide (1994).
