About this application

This is a planning application for window replacement at 246 Clapham Road London SW9 0PZ. Lambeth has handled 15,936 applications of this type. This one was decided in 85 days, 4 weeks longer than Lambeth's typical decision time. The site is in the South Lambeth Road conservation area, with 3 listed buildings nearby. There have been 2 other applications at this address. We hold 1,813 applications in total for the SW9 postcode area.

Why it was refused

  1. In the absence of a condition survey to demonstrate that the replacement of the existing windows is necessary, the loss of historic fabric and detailing has not been adequately justified. Furthermore, uncertainty remains regarding the accuracy of the proposed detailing. The proposal therefore fails to preserve the special architectural and historic interest of the listed building and would result in harm to its significance, contrary to Policy Q5, Q20 and Q22 of the Lambeth Local Plan 2021. This harm would not be outweighed by public benefits London planning@lambeth.gov.uk SW2 9QQ (paragraph 215 of the NPPF (2024).

From the council's decision notice.
