Why it was refused

  1. The proposed single storey rear extension by reason of its design, size and siting would appear overly prominent and increase the bulk of the rear elevation. As a result, the proposal would have an unacceptably adverse impact on the character and appearance of the dwelling and local area. The proposal is therefore contrary to policy DMP1 of the Brent Local Plan and guidelines within Brent’s Residential Extensions and Alterations Supplementary Planning Document.
  2. The proposed single storey rear extension by reason of its size and siting would appear overly prominent and increase the bulk of the rear elevation. As a result, the proposal would have an unacceptably adverse impact on the neighbouring amenities in terms of being overbearing and resulting in a loss of sunlight. The application is therefore contrary to policy DMP1 of the Brent Local Plan and guidelines within Brent’s Residential Extensions and Alterations Supplementary Planning Document.
  3. The provision of off-street parking space would exceed the maximum car parking allowance. It would encourage unnecessary car use and ownership in the area, adding to traffic congestion and contributing to climate change. The application is therefore contrary to Policy BT2 and Appendix 4 of the Local Plan.
  4. The proposal fails to provide sufficient soft landscaping or a safe arrangement for on-site car parking, resulting in harm to pedestrian safety and natural drainage. Therefore, the application is contrary to Policy BT2 of the Local Plan and Brent’s Domestic Vehicle Footway Crossover Policy.
