The Planning Committee of Sutton Council met on Wednesday 4 February 2026 to discuss several planning applications. The committee granted planning permission for a single-storey rear extension at 11 Overhill Road, Sutton, and approved amendments to an existing planning permission for 1 Wildes Cottages, Ewell Road, Cheam, to allow for an internal garage and other alterations. The committee also granted planning permission for the significant London Cancer Hub development on Cotswold Road, a hybrid application seeking detailed permission for Phase 1 and outline permission for future phases.

11 Overhill Road, Sutton, CR8 2JD

The committee unanimously granted planning permission for a single-storey rear extension at 11 Overhill Road. The application was brought before the committee due to the applicant being a member of the council. No objections were received, and the proposal was deemed to be acceptable in terms of land use, design, impact on residential amenity, biodiversity, highways, parking, trees, landscaping, fire safety, and CIL obligations.

1 Wildes Cottages, Ewell Road, Cheam, SM3 8AS

Planning permission was granted for amendments to an approved application at 1 Wildes Cottages, allowing for an internal garage, an internal entrance porch, and alterations to fenestration. This application was referred to the committee due to over 10 objections received, contrary to the officers' recommendation for approval. Concerns raised by objectors included the impact on the character of the Cheam Village Conservation Area, the visual detriment of a garage door, and potential noise from garage door operation. Officers concluded that the amendments were minor and would not harm the character and appearance of the area or neighbouring amenities. A condition was imposed to ensure the garage door is constructed in suitable materials and finished in an appropriate colour.

The London Cancer Hub, Cotswold Road, SM2 5NF

The committee granted planning permission for the London Cancer Hub development, a hybrid application comprising detailed permission for Phase 1 and outline permission for future phases. This ambitious project aims to transform the former Sutton Hospital site into a world-leading life-science and healthcare district. The development includes life science research and development floorspace, key worker accommodation, and public realm works.

The decision followed extensive debate, with significant public interest and numerous representations received. Key concerns raised by objectors and councillors included:

• Transport and Highways: Widespread concerns were voiced regarding the adequacy of parking provision (300 spaces for an estimated 3,000 jobs), the potential for increased traffic congestion, the impact on local roads and junctions, and the reliance on sustainable transport modes. While officers and Transport for London (TfL) were satisfied with the proposed mitigation measures, including junction improvements and a comprehensive travel plan, some councillors expressed scepticism about their effectiveness. The removal of the proposed link road from Phase 1 was also a point of contention.
• Allotments and Trees: The proposal to build a link road through the Belmont Allotments, leading to the loss of plots and mature trees, was a major point of objection. While the link road is now planned for a later phase, concerns remain about its eventual impact.
• Design and Massing: While the overall design was praised, some councillors and the Design Review Panel raised concerns about the scale and massing of certain buildings, particularly in relation to neighbouring residential properties and the overall townscape.
• Residential Accommodation: The inclusion of key worker accommodation in the outline phases was debated, with concerns raised about the potential for this to increase in the future and dilute the primary life science focus of the development.
• Community Engagement: Some objectors felt that community engagement had been insufficient, particularly regarding the transport strategy and the impact on the allotments.

Despite these concerns, the committee ultimately voted to grant permission, acknowledging the significant potential benefits of the London Cancer Hub for economic growth, job creation, and advancements in cancer research and treatment. The decision was made subject to conditions and a Section 106 agreement, which will secure various mitigation measures, including affordable housing, transport improvements, employment and skills initiatives, and biodiversity net gain. A specific condition was added to ensure that all reserved matters applications for future phases will be brought back to the planning committee for approval.

The committee also noted the importance of ongoing partnership working between the council, developers, and stakeholders to ensure the long-term success and integration of the London Cancer Hub within the borough.
