Why it was refused

  1. The development (in so far as it relates to the first floor flat at the rear of the application site) would result in sub-standard accommodation by reason of poor levels of outlook, daylight and inadequate private amenity space. Such would cause significant harm to the amenities of the future occupants of the flat. The application scheme would therefore fail to comply with Policies D3, D4 and D6 of London Plan (2021) and Policies SP4 and DM10 of Croydon Local Plan (2018).
  2. In the absence of a legal agreement, the application does not secure measures to mitigate the impacts of the development by reason of demands created for on-street car parking or offer a contribution towards sustainable transport initiatives in the vicinity to alleviate traffic generation created by the development. The proposal therefore conflicts with Policies T3, T4, T6 and DF1 of the London Plan (2021) and Policies SP8, DM29 and DM30 of the Croydon Local Plan (2018).

From the council's decision notice.
