Why it was refused

  1. The proposed development, by reason of its height, scale, massing, reduction in spacing between buildings, inappropriate roof form and contemporary design approach, would result in a development that appears overly prominent and out of keeping within the street scene, causing harm to the character and appearance of the host dwelling and the surrounding area. The proposal would therefore conflict with Policy D3 of the London Plan (2021) and Policies SP1, SP4, DM10 and DM10.7 of the Croydon Local Plan (2018).
  2. The proposed development, by reason of its height, scale, massing and siting adjacent to the shared boundary with 39A Grange Park Road, would result in an overbearing form of development causing unacceptable harm to the living conditions of neighbouring occupiers through loss of outlook and daylight. The proposal would therefore conflict with Policies D3 and D6 of the London Plan (2021) and Policies SP4 and DM10.6 of the Croydon Local Plan (2018).

From the council's decision notice.
