Why it was refused

  1. Insufficient information has been submitted to demonstrate that the replacement windows would not result in harm to the special interest of the listed building. The application fails to provide detailed existing window sections for all replacement windows or accurate drawings showing the existing windows within their reveals for all affected openings. Furthermore, the proposed glazing bar detailing is inaccurate, appearing overly heavy and rounded, which does not reflect the existing on-site detail. The proposal is therefore contrary to Policies Q5, Q11, Q20 and Q22 of the Local Plan (2021) and guidance within the SPD (2023) London planning@lambeth.gov.uk SW2 9QQ

From the council's decision notice.
