About this application

This is a planning application for a single storey rear extension at 146 Lower Addiscombe Road Croydon CR0 6AF. Croydon has handled 19,655 applications of this type. This one was decided in 53 days, 3 days quicker than Croydon's typical decision time. The site is in the East India Estate conservation area. There has been 1 other application at this address. In the past year there have been 1 application across Whittington And Streethay. We hold 5,304 applications in total for the CR0 postcode area.

Why it was refused

  1. By reason of its design, siting, size and scale the proposed development would be an incongruous, unsympathetic and visually dominant addition to the original building, streetscene and locality. The development proposed would have a harmful impact on the character and appearance of the East India Estate Conservation Area. The proposal as such is contrary to Policies SP4, DM10 and DM18 of the Croydon Local Plan (2018) and D3, HC1 of the London Plan (2021) and the provisions of the NPPF, as well as the guidance contained in the East India Estate CAAMP (2014), and would fail to meet the statutory test set out in Section 72(1) of the Planning (Listed Buildings and Conservation Areas) Act 1990.
  2. The proposed roof terraces would be detrimental to the amenities of the occupiers of nos. 144 and 148 Lower Addiscombe Road by reason of the loss of privacy and potentially harmful noise levels. The development would be an unneighbourly form of development and would thereby conflict with the policies DM10.6 of the Croydon Local Plan 2018 and D3 of the London Plan 2021.
  3. The proposal would result in substandard accommodation by reason of inadequate floor areas for Flats 1 and 3 and inadequate private amenity space for Flat 3, contrary to Policy DM10 of Croydon local Plan 2018 and Policy D6 of the London Plan 2021.
  4. In the absence of a legal agreement to secure a car free development and sustainable transport contributions, as well as car club membership for each residential unit for a period of 3 years, the proposal would take insufficient opportunities to promote sustainable modes of transport, contrary to policies SP6, DM29 and DM30 of the Croydon Local Plan 2018 and Policy T6 of the London Plan 2021.
