Sutton Council's Planning Committee has refused an application to convert a property at 48 Hallmead Road into a large House in Multiple Occupation (HMO), citing concerns over parking pressure and over-intensification.
The decision, made during a meeting on Wednesday, August 5, 2026, followed objections from residents regarding the change in the road's character, potential for increased noise and anti-social behaviour, waste management issues, and significant parking pressure.
The application sought to change the use of the property from a Class C4 (small HMO) to a Class Sui Generis (large HMO) to accommodate 10 rooms. Sutton Council's planning regulations define a 'small HMO' as Class C4, typically accommodating up to six people, while a 'large HMO' is Class Sui Generis and accommodates seven or more. Policy 10 of the Sutton Local Plan states that proposals for new large HMOs will be permitted provided they do not lead to a concentration of HMOs in the vicinity that harms the character of the area. A concentration is considered to exist where more than 20% of properties within 100 meters are HMOs.
The property at 48 Hallmead Road currently has a lawful use as a small HMO (Class C4), having been granted a Certificate of Lawful Use on 14.01.2025. Extensions have been approved, and it currently accommodates up to six people. The applicant proposed mitigation measures including cycle parking for 10 bikes and a 'no car ownership policy' for residents. Covered and secure bin stores were also proposed for waste management. The Environmental Health Licensing Team had confirmed the layout meets requirements for a 10-occupant HMO and had licensed the property for this number.
However, the committee ultimately refused the application based on concerns that the increased parking pressure and over-intensification of the site would detrimentally affect the safe operation of the public highway and the amenities of neighbouring properties. The committee considered the impact on neighbouring properties in terms of privacy, sunlight or daylight exposure, noise and disturbance, sense of enclosure, and loss of outlook, referencing Policy 29 of the Sutton Local Plan.
The application had previously been refused on 26.01.2026 (DM2025/01482) for failing to provide a Parking Stress Survey to demonstrate that the proposed development, with no additional off-street parking, would not result in an unacceptable increase in on-street parking demand. This refusal was upheld on appeal.
While the officer's report noted that the property had lawful use as a small HMO and that the Highways Team had no objection based on the submitted parking survey and the property's PTAL rating, the committee's decision reflected the concerns raised by residents and the previous appeal outcome. The PTAL rating for 48 Hallmead Road was 4, indicating good public transport accessibility. The Highways Team had concluded no highway objection based on this rating and proposed mitigation measures, stating that strict application of standard residential parking requirements would be unreasonable given the property's location and the modest marginal increase in occupiers.
