Why it was refused

  1. Impact on heritage assets and design quality: The proposed first-floor rear extension, through the loss of the existing rear pitched roof, and the proposed second-floor rear extension, by reason of its excessive height, bulk, scale, massing and poorly considered design, would fail to respect the historic form and vernacular character of the locally listed building and would be harmful to the character and appearance of the Rye Lane Peckham High Street Conservation Area. The development would be prominent in significant views of the historic terrace and would erode its established roofline, scale and townscape character. The proposal would therefore fail to conserve the locally listed building or preserve or enhance the character and appearance of the conservation area, and would constitute poorly designed development. The identified harm is not outweighed by the public benefits of the proposal. The development is therefore contrary to Policies P13 (Design of Places), P14 (Design Quality), P20 (Conservation Areas) and P26 (Local List) of the Southwark Plan 2022, the relevant provisions of the London Plan 2021 and National Planning Policy Framework (2026).
  2. The proposed combined lounge/dining/kitchen area of 18.6sqm falls significantly below the required 24sqm. This would result in an inadequate standard of living accommodation. The proposal is therefore contrary to Chapter 14 (Achieving well-designed places) of the National Planning Policy Framework, Policies D4 (Delivering good design) and D6 (Housing quality and standards) of the London Plan 2021, Policy P15 (Residential Design) of the Southwark Plan 2022 and the Council's relevant residential design standards.
  3. The proposed extensions, by reason of their scale, height and close proximity to the two existing windows serving No. 106 Peckham High Street on the west elevation, would result in an unacceptable sense of enclosure, loss of outlook and reduction in natural light for neighbouring occupiers. The development would therefore have an adverse impact on the residential amenity of No. 106 and would be contrary to Policy P15 (Residential Design) of the Southwark Plan 2022 and the relevant provisions of the London Plan 2021.
  4. The scheme would fail to provide adequate accessible and secure bin store(s) for the proposed residential dwellings and commercial shop. This southwark.gov.uk 2 Southwark Council, PO Box 64529, DECISION NOTICE LBS Registered Number: 26/AP/0301
