Why it was refused

  1. The proposed single storey rear extensions, by reason of their siting coupled with the excessive height and depth, would result in a materially harmful impact to the living conditions of occupants of Nos. 68 and 72 Crantock Road. The scale and position of the extensions would create an overbearing and visually intrusive form of development, adversely affecting the outlook from the nearest rear-facing windows. Furthermore, the proposal would lead to a loss of daylight and sunlight to these neighbouring properties. As such, the development fails to secure a high standard of amenity for existing residents, contrary to Paragraph 135(f) of the National Planning Policy Framework (December 2024), and Policies QD7 and QD9 of the Lewisham Local Plan (July 2025).

From the council's decision notice.
