Why it was refused

  1. The proposal would result in the loss of an original three bedroom house with an internal floor area less than 130m2. There would also be no provision of a replacement dwelling with three or more bedrooms, for which there is an identified need in the borough and would thereby conflict with Policies SP2.7 and DM1.2 of the Croydon Local Plan (2018).
  2. The required refuse would result in visual clutter that would harm the visual appearance of the streetscene and the character of the area and would thereby conflict with Policies SP4, DM10 and DM13 of Croydon Local Plan (2018) and Policy D3 of London Plan (2021).
  3. The proposed single storey rear extension would be detrimental to the amenities of the occupiers of the adjoining property, no. 86 Isham Road by reason of its size, siting, and height resulting in loss of outlook, visual intrusion and overbearing impact and would thereby conflict with Policies SP4 and DM10 of the Croydon Plan (2018) and Policy D3 of the London Plan (2021).
  4. The proposed development would result in sub-standard living accommodation for future residents by virtue of inadequate floor areas, poor internal and external layout, poor outlook and light, privacy, lack of storage, poor outdoor amenity space and that it has not been demonstrated that the required floor to ceiling heights would be achieved and would thereby conflict with Policies SP2 and DM10 of the Croydon Local Plan (2018), Policies D3 and D6 of the London Plan (2021) and the Technical Housing Standards - Nationally Described Space Standard (2015).
  5. The applicant has failed to demonstrate through Parking Stress Surveys that the overspill parking would not exacerbate the on-street parking stress for existing residents and would thereby conflict with policies SP8, DM29, and DM30 of the Croydon Local Plan (2018) and Policies T4, T6 and T6.1 of the London Plan (2021).
  6. The applicant has failed to demonstrate that adequate cycle storage facilities would be provided to serve the needs of future occupiers which would be accessible and would thereby conflict with Policies DM16, DM29 and DM30 of the Croydon Local Plan (2018) and Policy T5 including table 10.2 of the London Plan (2021).
  7. The applicant has failed to demonstrate that adequate refuse storage facilities would be provided to serve the development and meet the needs of future residents, and which would be conveniently located and easily accessible by occupants, and operatives. The proposal would thereby conflict with Policy DM13 of the Croydon Local Plan (2018) and Policies D6 including table 3.2 and SI7 of the London Plan (2021).
