Why it was refused

  1. The proposed single-storey rear extension, by reason of its excessive scale and depth along the shared boundary would result in significant overbearing harm, increased sense of enclosure and overshadowing, and reduced outlook to the adjoining property at No. 35 Senlac Road, contrary to paragraphs 131 and 135 of the National Planning Policy Framework (2024), Policy D3 of the London Plan (2021), Policy QD9 of the Lewisham Local Plan (2025), and the Alterations and Extensions SPD (April 2019).

From the council's decision notice.
