Why it was refused

  1. The proposed replacement windows would fail to preserve the special architectural and historic interest of the Grade II listed building and the wider listed terrace. and would result in less than substantial harm to the significance of the heritage asset and its setting. The harm identified is not outweighed by public benefits. the proposal fails to demonstrate that the works would preserve or enhance the character and appearance of the conservation area, contrary to policies Q5, Q8, Q20 and Q22 of the Lambeth Local Plan (2021) and the Lambeth London planning@lambeth.gov.uk SW2 9QQ Design Guide (2023). This harm would not be outweighed by public benefits (paragraph 215 of the NPPF (2024)).

From the council's decision notice.
