Why it was refused

  1. The site lies within Flood Zone 2 and areas at risk of fluvial and surface water flooding. The submitted Flood Risk Assessment and flood mitigation measures proposed fail to demonstrate that the development would be safe for its lifetime, as it does not adequately address the flood risk to the proposed ground floor sleeping accommodation, provide safe evacuation arrangements, or incorporate sufficient flood resistance and resilience measures. The proposal is therefore contrary to Policy CP28 of the Core Strategy (2010), and Policies DMD59, DMD60 and DMD62 of the Development Management Document (2014), Policies SI12 and SI13 of the London Plan (2021), Policies F4, F6 and F7 of the National Planning Policy Framework (2026).
  2. The proposed raised rear access steps and internal raised steps, introduced as a flood mitigation measure, represent a poor and contrived design solution that would result in an inaccessible and inconvenient means of access for future occupiers, particularly those with mobility impairments. The proposal would fail to provide an inclusive residential environment and therefore conflicts with Policy D5 of the London Plan (2021), Policy DMD37 of the Development Management Document (2014) and Policy DP3(f) of the National Planning Policy Framework (2026).

From the council's decision notice.
