Why it was refused

  1. The proposed replacement of timber windows with aluminium units would fail to preserve or enhance the character and appearance of the conservation area. The use of aluminium, which is not characteristic of the area, would result in harm to its significance without any clear justification or public benefit. The proposal is therefore contrary to policies Q5, Q11 and Q22 of the Lambeth Local Plan (2021) and the Lambeth Design Guide (2023). This harm would not be outweighed by public benefits (paragraph 215 of the NPPF (2024)). London planning@lambeth.gov.uk SW2 9QQ
  2. Insufficient information has been submitted to demonstrate that noise harm arising from the proposed air conditioning unit can be appropriately mitigated and would not result in heritage harm.

From the council's decision notice.
