Why it was refused
- The proposed large sui generis HMO, accommodating up to 8 occupants, would significantly intensify activity compared to a single-family dwelling. The associated comings and goings of occupants and their visitors and the associated infrastructure required (car parking, commercial bins, cycle parking) for an HMO of the scale would harm the established low density residential character of the area and would introduce an excessive scale of development in an area dominated by single family dwellinghouses. The proposal is therefore contrary to Policies CP5 and CP30 of the Enfield Core Strategy (2010), Policies DMD5, DMD8 and DMD68 of the Enfield Development Management Document (2014), and Policies D3 and D14 of the London Plan (2021).
- The development, by virtue of its scale and intensity of occupation, would result in unacceptable levels of noise and general disturbance within a quiet residential setting, harming the amenities of neighbouring residential occupiers. The proposal is therefore contrary to Policy DMD 68, DMD 8 and DMD 5 of the Enfield Development Management Document (2014), and D14 of the London Plan (2021), and Section 12 of the National Planning Policy Framework (2024).
- 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 8 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 DMD Policy 45.
From the council's decision notice.
