Why it was refused

  1. Insufficient information has been submitted to demonstrate that the proposal would result in a design that would preserve or enhance the appearance of the dwellinghouse and by implication the North Kilburn Conservation Area. Therefore, it is considered that the applicant has not demonstrated a clear understanding of the architectural or historic significance of a heritage asset and has failed to demonstarte an accpetable impact on this. The proposal hasd the potential to unacceptably harm the appearance of the conservation area, contrary to policies DMP1 and BHC1 of Brent’s Local Plan (2019-41) and the North Kilburn Conservation Area Design Guide.

From the council's decision notice.
