Flexible C3/C4 conversion at 50 Belgravia Road, Portsmouth
Summary of planning committee decision
Decided by Portsmouth Planning Committee on 17 Jun 2026.
What was proposed
The application sought flexible use of two houses as one dwellinghouse or one house in multiple occupation, with six bedrooms and shared facilities.
“The proposal is for the change of use of the property from two houses (Class C3) to a single dwellinghouse (Class C3) or House of Multiple Occupation (HMO) (Class C4). If granted, this would allow the applicant to use the property flexibly as either a C4 HMO or a C3 dwellinghouse for a period of up to 10 years under the rights granted under Class V, Part 3 of the Town and Country Planning (General Permitted Development) (England) Order 2015.”
“Ground Floor - two bedrooms (single occupancy); communal combined amenity area; shared bathroom, and shared WC. • First Floor - Four bedrooms (single occupancy); shared bathroom.”
Officer report
What officers recommended
Officers recommended conditional permission, concluding the proposal was acceptable and complied with relevant planning policies and national objectives.
“Having regard to all material planning considerations and representations it is concluded that the proposed change of use is acceptable and would be in accordance with the relevant policies of the Portsmouth Plan (2012), the HMO SPD, and the objectives of the National Planning Policy Framework (NPPF) (2024).”
Officer report
Consultation responses
Highways raised no objection, housing comments found suitable living space, and waste requirements differed depending on whether the property was used as an HMO or dwellinghouse.
“No objection. There is suitable living space for the proposed number of occupants. The property would likely require a licence under Part 2, Housing Act 2004.”
“If used as an HMO, the property would require one 360L refuse bin, one 360L recycling bin, and space for a third bin for mixed fibres when the Simpler Recycling system is introduced. If occupied as a C3 dwellinghouse, the expected provision would be one 180L refuse bin and one 240L recycling bin, with space for a third bin when the Simpler Recycling system is introduced.”
Officer report
Members’ discussion
Members discussed housing loss, bathroom provision, natural light, space standards and building regulations, while noting no planning reasons for refusal.
“Greater weight is given to natural light and outlook in habitable rooms (such as bedrooms and living spaces) rather than in circulation spaces, bathrooms, or landings. Bedroom windows within the proposal provide adequate light and reflect the building’s Victorian character. Bathrooms and WCs are not required to have natural light, as they are not classified as habitable rooms and may be artificially ventilated.”
“Members' Comments Concern was expressed regarding the loss of two separate dwelling houses and the reduction of family accommodation in the Copnor area. Concerns were raised about the adequacy of bathroom provision for six bedrooms (two bathrooms and one WC).”
Minutes
The committee’s decision
The committee granted conditional planning permission and added an informative about building regulations considerations for lighting.
“RESOLVED Conditional planning permission was granted with an informative note to be included regarding building regulations considerations for lighting.”
