Earlier permission
A 2024 householder permission approved side, rear and porch extensions, and that permission remains extant.
“A list of the relevant planning history related to the property can be found in Appendix 2.”
“A Householder planning application was approved on 10-07-24 under reference 43721/APP/2024/1306 for the ‘Construction of a part single, part two-storey side extension, single -storey rear extension, and front porch’. This permission currently remains extant.”
Officer report
What officers recommended
Officers recommended approval because the proposal would provide acceptable housing, amenity space, parking and refuse arrangements without significant harm to neighbours or the area.
“The proposed development would have an acceptable impact on the character and appearance of the area and would not result in significant harm to the amenities of neighbouring occupiers. The proposal would provide a satisfactory standard of accommodation for future residents, together with adequate amenity space, parking, cycle storage and refuse provision.”
“The proposal is considered to comply with the Development Plan, and no material considerations indicate that a contrary decision should be taken. Moreover, significant weight is afforded to the provision of additional housing in light of the fact the Council is unable to demonstrate a 5 -year housing land supply. Consequently, the application is recommended for approval subject to the conditions set out in Appendix 1.”
Officer report
Consultation responses
The Highway Authority raised no objection subject to a cycle-storage condition, while a 32-signature petition and seven individual objections raised concerns about character, parking, amenity and waste.
“Increased pressure on local infrastructure including parking, waste collection services, local amenities and detriment of existing residents. An assessment of the impacts on parking provision, refuse storage and residential amenity have been discussed within the relevant sections of this report.”
“No objection is raised to the proposal. The existing vehicular and pedestrian access arrangements would be retained and the provision of one parking space per dwelling is considered acceptable, having regard to the site's PTAL rating, proximity to local bu s services and the existing level of usable on-site parking.”

Who spoke
The lead petitioner addressed the committee, while the applicant and agent did not attend.
Members’ questions
Members questioned refuse and cycle storage, parking pressure, noise, possible HMO use, housing definitions, space standards, landscaping and alleged unlawful activity.
“Members sought clarification regarding the location and security of the proposed refuse and cycle storage facilities. Officers advised that the refuse storage area would be located adjacent to the parking spaces and that further details would be secured through a landscaping condition requiring appropriate enclosure and screening. Officers further advised that cycle storage would be located within the rear garden areas and accessed via the side passage.”
“Members referred to cycle storage arrangements and questioned whether the location of the storage areas might discourage cycling. Officers explained that whilst London cycling design guidance generally favoured storage located to the front of properties, practical considerations also needed to be taken into account.”
