Why it was refused

  1. The proposed replacement timber sash windows and front door, by reason of the absence of detailed section drawings and insufficient information regarding their design, materials and detailing, have failed to demonstrate that they would preserve or enhance the character and appearance of the host property and the Queen’s Park Conservation Area. In the absence of such information, the Local Planning Authority cannot be satisfied that the proposed works would respect the historic character and architectural detailing of the building or the wider conservation area. The proposal therefore conflicts with the Queen’s Park Conservation Area Design Guide, Policy HC1 of the London Plan (2021), Policies BHC1 and DMP1 of the Brent Local Plan 2019-2041, and the statutory duty to preserve or enhance the character or appearance of conservation areas.

From the council's decision notice.
