Why it was refused

  1. By reason of the loss of the historic roof structure and the loss of the side extension's current subordination, the proposal would cause harm to the listed building, no. 359 Clapham Road. The harm would not be outweighed by public or heritage benefits. The proposals are thereby contrary to the objectives of the NPPF (2026), Policies Q5, Q8, Q11 and Q20 of the Lambeth Local Plan (2021) and the Lambeth Design Guide SPD (2023).

From the council's decision notice.
