Why it was refused

  1. The dormer extension, by reason of its design, height, profile and siting, would appear out of keeping with the surrounding townscape and would fail to preserve or enhance the character and appearance of the South Norwood Conservation Area. Therefore, the proposal is considered contrary to policies D3, D4 and HC1 of the London Plan (2021); and policies DM10, DM18 and SP4 of the Croydon Local Plan (2018), and the South Norwood Conservation Area Appraisal and Management Plan (2022).
  2. The proposed dormer extension by reason of design, height and proximity to neighbouring dwellings, would result in an undue sense of enclosure and loss of light and outlook to the detriment of adjoining amenity. Therefore, the proposal is considered contrary to policy D3 of the London Plan (2021) and policy DM10 of the Croydon Local Plan (2018).
  3. A legal agreement was not submitted with the application to mitigate the impacts of the development on on-street parking stress within a local controlled parking zone to the detriment of the availability of on-street parking and movement of vehicular traffic on local streets. Therefore, the proposal would be contrary to policies T4 and T6 of the London Plan (2021) and policies SP8, DM29 and DM30 of the Croydon Local Plan (2018).
