Why it was refused

  1. The proposed development, by virtue of its substandard internal and external living conditions for a 10 person HMO, including undersized internal amenity space, the provision of kitchens within bedrooms, and the lack of any external amenity provision, together with the submission of an inadequate and non–site specific HMO Management Plan, and its contribution to an over concentration of HMOs in the surrounding area, the proposal would therefore result in poor quality accommodation and harm to the character and amenity of the area contrary to Policy BH7 (criteria b, c and e) of the Brent Local Plan 2019–2041.
  2. The proposed rear dormer, front rooflights and associated alterations, by virtue of their design, detailing and failure to respect the traditional roof form and architectural character of the Kensal Rise Conservation Area, would fail to preserve or enhance its character and appearance. This results in less than substantial harm to a designated heritage asset, with no public benefits to outweigh that harm, contrary to Section 72(1) of the Planning (Listed Buildings and Conservation Areas) Act 1990, the NPPF (2024) and Policies BHC1 and DMP1 of the Brent Local Plan 2019–2041.

From the council's decision notice.
