Why it was refused

  1. Due to the overall design, scale and cumulative size of the proposed roof extensions, the proposed development would fail to respect the character, appearance and roofscape of the host dwelling and would appear incongruous in the streetscene and the surrounding area, contrary to DMP1 & BD1 of the Brent’s Local Plan (2019-2041) and Brent’s Residential Extensions & Alterations SPD (2025).
  2. In the absence of an arboricultural impact assessment, the application has failed to demonstrate that the proposed development would not harm the existing off-site trees. As such the proposed development fails to comply with Policy BGI2 and DMP1 of the Brent Local Plan 2019-2041.

From the council's decision notice.
