Why it was refused

  1. The proposed development would fail to provide an acceptable standard of accommodation for future occupiers. The proposed shared communal space would be limited to a kitchen area which, by reason of its long, narrow and constrained layout, would provide poor circulation and insufficient opportunities for dining, recreation and meaningful social interaction, resulting in an unsatisfactory communal environment for residents. The communal space would also be characterised by limited levels of natural daylight, sunlight and outlook, thereby reducing its functionality, attractiveness and overall quality. In addition, Bedroom 2 would experience inadequate levels of outlook, daylight and sunlight owing to the restricted relationship between its side and rear-facing windows and the constraints arising from the proposed en-suite arrangement. Collectively, these deficiencies would result in substandard living conditions and a poor quality living environment for future occupiers. The proposal is therefore contrary to Policy D6 of the London Plan (2021), Policy CP4 of the Enfield Core Strategy (2010), Policies DMD5 and DMD8 of the Enfield Development Management Document (2014), and paragraphs 131 and 139(f) of the National Planning Policy Framework (2026).
  2. The proposed development has failed to demonstrate that it would be safe from flood risk for its lifetime. In the absence of a satisfactory Flood Risk Assessment and Flood Management/Evacuation Plan, insufficient information has been provided to demonstrate that the proposed ground-floor sleeping accommodation would be adequately protected from the risk of surface water flooding during the 1 in 100-year rainfall event, including an appropriate allowance for climate change. Furthermore, it has not been demonstrated that future occupants would have access to safe refuge and safe means of escape in the event of flooding. The proposal therefore fails to adequately manage and mitigate flood risk and would place future occupants at an unacceptable risk of harm. As such, the proposal is contrary to Section 14 of the National Planning Policy Framework (2026), Policies SI12 and SI13 of the London Plan (2021), Policy CP28 of the Enfield Core Strategy (2010), Policies DMD59, DMD60, DMD61 and DMD62 of the Enfield Development Management Document (2014), and the Enfield Strategic Flood Risk Assessment (2008).

From the council's decision notice.
