Why it was refused

  1. While the scheme introduces two family-sized dwellinghouses, this benefit does not outweigh the significant harm caused by the net loss of five self-contained flats, which are in high demand locally, and therefore represents an unacceptable reduction in housing choice and supply, contrary to Policy BH10 of the Brent Local Plan 2019 – 2041.
  2. Due to excessive depth, the proposed rear extensions to the existing rear outriggers would have a detrimental impact on the character and appearance of both the host properties and the rear of the terrace of which they are part, contrary to DMP1 of Brent’s Local Plan (2019-2041) and Brent’s Residential Extensions and Alterations SPD (2025).

From the council's decision notice.
