Why it was refused

  1. The proposed development, by reason of the lack of accurate and sufficient information relating to the existing use of the site, including the number and status of residential units and the use of the rear outbuilding, fails to establish a clear and lawful baseline position. As such, the Local Planning Authority is unable to determine whether the proposal would result in an appropriate level of residential intensification or an overdevelopment of the site. Notwithstanding the site’s location within a PTAL 4 area, the proposal fails to demonstrate compliance with Policy BH4 of the Brent Local Plan (2019–2041) and Policies H1 and H2 of the London Plan (2021)
  2. The proposed development, by reason of its poor and constrained internal layout, excessive depth, and limited access to natural light and outlook, alongside privacy concerns, would result in substandard living conditions for future occupiers, contrary to Policy D6 of the London Plan (2021)
  3. The proposed development fails to demonstrate the provision of sufficient, functional, and private external amenity space to the detriment of future occupiers, contrary to Policy BH13 of the Brent Local Plan (2019–2041)
  4. The proposed extensions, by reason of their excessive cumulative depth, scale, and siting, together with the introduction of an additional front entrance and the creation of a poorly configured rear form of development, would result in a cramped, contrived, and visually intrusive addition that fails to respect the character, appearance, and spatial qualities of the host property and the surrounding area. The development is therefore contrary to Policy DMP1 of the Brent Local Plan (2019–2041), Brent Design Guide SPD1 (2018), and Brent’s Residential Extensions and Alterations SPD (2025).
  5. By reason of its scale, siting, and layout, together with the intensification of the site, the proposed extensions would result in an unacceptable level of harm to the amenity of neighbouring occupiers. The proposal is therefore contrary to Policy DMP1 of the Brent Local Plan (2019-2041) and the guidance contained within SPD1 (2018) and the Residential Extensions and Alterations SPD (2025).

From the council's decision notice.
