Why it was refused

  1. The proposed ground-floor rear extension, by reason of its excessive depth, scale and proximity to the shared boundary with No. 32 Lansbury Road, would give rise to an unneighbourly form of development resulting in an unacceptable loss of outlook, increased sense of enclosure and reduction in daylight to neighbouring occupiers. The proposal would therefore be contrary to Policy D4 of the London Plan (2021), Core Policy 30 of the Enfield Core Strategy (2010) and Policies DMD 8 and DMD 11 of the Enfield Development Management Document (2014).
  2. The proposed first-floor rear extension, by reason of its depth, height and proximity to the shared boundary with No. 28 Lansbury Road would result in an unacceptable loss of outlook and increased sense of enclosure to neighbouring occupiers. The proposal would therefore be contrary Section 12 of the National Planning Policy Framework (2024), Policy D4 of the London Plan (2021), Core Policy 30 of the Enfield Core Strategy (2010) and Policies DMD 8 and DMD 11 of the Enfield Development Management Document (2014).
  3. The proposed development, in the absence of an adequate flood risk assessment, fails to demonstrate how proposed measures manage the risk of flooding contrary to Section 14 of the National Planning Policy Framework (2024), Policies SI.12 and SI.13 of the London Plan, Policies CP21 and CP28 of the Enfield Core Strategy, Policies DMD59, DMD60 and DMD61 of the Enfield Development Management Document (2014).
