Why it was refused

  1. The proposed conversion of the existing single family dwellinghouse into two self-contained flats, by reason of the failure to provide a compensatory family-sized unit and the cumulative concentration of flat conversions along this section of Stainton Road exceeding the 1-in-5 threshold, would result in the unjustified loss of family housing stock and an excessive concentration of subdivisions harmful to the established residential character and function of the area. The proposal is therefore contrary to Section 5 of the National Planning Policy Framework (2024), Policy D3 of the London Plan (2021), Policies CP4 and CP5 of the Enfield Core Strategy (2010), and Policies DMD5, DMD6 and DMD37 of the Enfield Development Management Document (2014).
  2. The proposed development, by virtue of the absence of any private amenity space serving the first floor flat, would result in a substandard form of accommodation incapable of meeting the reasonable needs of future occupiers, contrary to Section 12 of the National Planning Policy Framework (2024), Policies D4 and D6 of the London Plan (2021), Policy CP 30 of the Enfield Core Strategy (2010), and Policy DMD 9 of the Enfield Development Management Document (2014).

From the council's decision notice.
