Why it was refused

  1. The proposed windows, by reason of their design and failure to accurately reflect the proportions, detailing and appearance of the original windows, would detract from the architectural character of the host property and fail to preserve the character and appearance of the Queen’s Park Conservation Area. As such, the proposal conflicts with Policy DMP1 of the Brent Local Plan 2019-2041 and the Queen’s Park Conservation Area Design Guide (2013).

From the council's decision notice.
