10-Bedroom HMO Refused in Quiet Family Neighbourhood, Prestwich

The Application

The applicant sought planning permission to change the use of a dwelling and an existing swim school building at 31 Grosvenor Street, Prestwich to a ten-bedroom House in Multiple Occupation (HMO), classified as Sui Generis. The proposals also included alterations to the fenestration of the pool building and a loft conversion with two rear dormer windows.

Grosvenor Street is a predominantly family-oriented residential street characterised by Edwardian terraced and semi-detached properties. The conversion of two buildings — a family home and a commercial swim school — into a large-scale HMO of this nature represented a significant intensification of use on the site.

The Client's Concern

The client contacted Planning Voice after discovering that a planning application had been submitted to convert a nearby property into a thirteen-bedroom house in multiple occupation. They lived on a small, quiet street with only a handful of residences and a very small number of existing occupants. The prospect of a single building accommodating thirteen people in such a confined setting alarmed the client, who was concerned about the dramatic change in the character of the street, the increase in noise and activity, and the pressure on already limited on-street parking. The client felt that the scale of the proposed HMO was wholly disproportionate to the size and nature of the surrounding area and sought professional assistance to challenge the application on proper planning grounds.

Our Objection

Planning Voice prepared a detailed, policy-based objection on behalf of neighbouring residents. Our submission identified four principal areas of concern, each grounded in the adopted development plan and national policy.

1. Impact on Residential Character and Amenity

A ten-bedroom HMO generates significantly greater levels of activity, noise, and coming-and-going than a family dwelling. Bury's Local Plan and the National Planning Policy Framework (NPPF 2024) both require that proposals respect the character and amenity of the surrounding area. A development of this scale and type was fundamentally at odds with the quiet, family-oriented residential environment of Grosvenor Street.

We argued that the concentration of occupants in a single building — with the associated noise from communal areas, unsociable hours of movement, and intensified use of outdoor spaces — would cause demonstrable harm to the living conditions of neighbouring residents.

2. Harm to Architectural Character

The proposed dormer windows and alterations to the former pool building were assessed against Bury Council's design policies and the character of the surrounding Edwardian streetscene. The proposals would introduce features inconsistent with the established architectural vocabulary of the area, causing harm to the visual quality and uniformity of the street.

3. Drainage and Flood Risk

The site already incorporated a pool building, and the area had pre-existing drainage constraints. Our objection drew attention to the absence of adequate drainage assessment with the application and argued that the intensification of use would exacerbate existing pressures on the local drainage network, potentially affecting neighbouring properties.

4. Parking and Highway Safety

Grosvenor Street was already experiencing pressure on on-street parking. A ten-bedroom HMO would introduce a significant number of additional occupants, each potentially with one or more vehicles, without the application demonstrating any adequate parking provision on site. Our objection noted that the proposal failed to meet the council's adopted parking standards and that the resulting overspill would create conditions harmful to highway safety and the amenity of neighbouring residents.

What This Case Demonstrates

HMO applications are one of the most common planning disputes affecting residential neighbourhoods. They often proceed on the basis that occupancy is not a planning matter, but the planning system does regulate HMOs — particularly Sui Generis HMOs of six or more occupants — through use class policy, local HMO concentration policies, and the general amenity and character tests that apply to all development.

This case illustrates that a well-structured objection, which translates legitimate neighbourhood concerns into policy-based planning arguments, can be decisive. The applicant in this instance did not appeal the refusal.
