Why it was refused

  1. The proposed part single storey part first floor rear conservatory extension, by reason of its bulk, scale, massing, design, siting and materiality, would be harmful to the architecture of the host building, the visual amenity of the street scene and character of the area. As such, the proposal is contrary to the National Planning Policy Framework (NPPF), policies 7.4 and 7B of the Ealing Development Management Development Plan (2013) and policies D3 and D4 of the London Plan (2021), the Ealing Housing Design Guidance (2022) and policy DAA of the draft Ealing Local Plan Regulation 22 (2024).
  2. The proposed part ground part first floor conservatory extension, by reason of its depth, height and elevated position along the boundary, would result in loss of outlook, natural light, and increase in the sense of overbearing and enclosure, to the detriment of the amenity of occupants at Nos. 211 and 213 Tentelow Lane. As such, the proposal is contrary to policies D3 and D6 of the London Plan (2021), policy 7B of the Ealing Development Management DPD (2013) and policy DAA of the draft Ealing Local Plan Regulation 22 (2024).

From the council's decision notice.
