Why it was refused

  1. The change of use into a house of multiple occupation (HMO) results in more than one property out of a consecutive row of five properties being converted and results in a clustering of conversions along this terrace of buildings, unduly at odds with the predominant pattern of single family dwellinghouses along the road, contrary to Policies CP30 of the Enfield Core Strategy (2010) and DMD5 and DMD 37 of the Enfield Development Management Document (2014) and National Planning Policy Framework (2026).
  2. By virtue of the contrived and impractical layout of the ground floor bathroom located directly off the kitchen on the ground floor, giving rise to concerns regarding the suitability and practicality of the arrangement, the proposal results in a poor quality of accommodation for future occupiers. The proposal is therefore contrary to the National Planning Policy Framework (NPPF, 2026), Policies D5 and D6 of the London Plan (2021), DMD 5, DMD 6, DMD 8 and DMD 37 of the Development Management Document (2014) and Policy CP30 of the Core Strategy (2010), as well as the Nationally Described Space Standards (2015).
  3. The applicant has failed to provide sufficient evidence, including a robust on street parking stress survey, to demonstrate that the net increase in parking demand arising from the proposed 6 person HMO can be accommodated without resulting in unacceptable parking stress or adverse impacts on the operation and safety of the surrounding highway network. The proposal is therefore contrary to London Plan Policy T2 and Development Management Document Policy 45.

From the council's decision notice.
