Life-science district at London Cancer Hub, Cotswold Road, Sutton

What was proposed

The hybrid application proposed a life-science district, with detailed buildings and landscaping alongside outline future buildings, housing, allotments and a link road.

“The application seeks planning permission for the comprehensive redevelopment of the site to create a new life-science district. It is submitted as a hybrid planning application, consisting of two distinct elements. The first element seeks full detailed planning permission for "Phase 1," comprising the erection of three buildings, landscaping, and access works.”

“The masterplan proposes a total of up to 90,941 square metres of Gross Internal Area (GIA) across the entire site. The primary land use will be life sciences research and development (Class E(g) and/or B2), comprising up to 78,482 square metres. To support the scientific community, the application also proposes up to 1,562 square metres of flexible non-residential amenity floorspace (Class E and/or Sui Generis), which may include retail, cafés, or wellness centres.”

Officer report

The site and design

Phase 1 comprised three life-science buildings, public spaces, walking and cycling routes, parking, and a pedestrian-focused access strategy.

“Access, Transport and Parking 4.12 Vehicular access to the site will be maintained via the existing junctions on Cotswold Road. The application outlines a pedestrian-focused movement strategy, with an east-west pedestrian spine connecting the main public spaces. A future link road connecting Cotswold Road to Brighton Road is proposed in outline, which would require the partial relocation of the Belmont Allotments to the northern part of the site.”

“The scheme proposes a maximum of 300 car parking spaces across the entire development to support the life science uses. In Phase 1, 134 spaces will be delivered. The majority of these (approximately 60) will be located in a lower-ground undercroft beneath buildings A1 and A2, utilising the site's topography to keep vehicles out of sight. The remaining spaces will be at surface level, positioned at the site perimeter to minimise the dominance of cars.”

Officer report

Earlier design work

Design review supported improvements but previously questioned transport, parking, landscape, biodiversity, tree loss and the form of future buildings.

“The Panel noted there has been significant progress since the previous design review including improvements to connectivity, massing, townscape views, site layout and articulation of the development but they were not yet convinced that the proposed transport and parking strategy was fully justified based on the evidence presented.”

“Not all criticisms of the scheme have been fully resolved, namely the Panel have not had the opportunity to review the submitted parameter plans and design code which set the principles and design quality standard against which future reserved matters applications and details regarding the link road and residential block (Parcel C) are proposed to be developed at the reserved matters application stage.”

Officer report

What officers recommended

Officers recommended approval because the scheme supported the life-science district, regeneration, design quality, affordable key-worker housing and sustainable transport with mitigation.

“The proposed development has been designed to provide flexible and adaptable floorplats, to include grow-on space, to support the needs arising from micro, small, and medium sized life sciences tenants allowing future occupiers to scale. In so far as the design of the scheme achieves this it has the potential to support long-term sustainable growth of this specialist cluster.”

“For this reason, a comprehensive review has been carried out over an extended period in close collaboration with TfL, Surrey County Council, the Council’s independent advisors Norman Rourke Pryme (NRP) and the applicant’s transport consultants, Arup.”

Officer report

What consultees said

TfL, highway authorities and other consultees raised no objections subject to mitigation and conditions, while tree officers noted significant future tree loss.

“Officer Comment: Noted. Various conditions and obligations to mitigate transport impacts and impacts of construction secured through conditions and the Heads of Terms. LBS Tree Officer Accepted that the local plan site allocation would inevitably necessitate some tree loss on the site.”

“LBS Tree officer has assessed the tree loss and mitigation proposals associated with the development and considers that expected mitigation proposed for phase 1 could achieve an amenity value on site that offsets the loss within 10 years and that this would be acceptable.”

Officer report

Who spoke

Residents’ representatives, an allotment representative, a resident, a ward councillor and supporters for the applicant addressed the committee.

What members debated

Members considered the proposal’s design and benefits alongside concerns about public transport, difficult junctions, cyclist safety, parking and the effectiveness of mitigation.

“Planning Committee 4 February 2026 5 Members raised concerns regarding cyclist safety at the nearby junction, particularly in light of anticipated increases in traffic accessing the site and the potential for congestion. Officers explained that proposed cycle routes and improvements along Brighton Road formed part of the mitigation measures intended to improve cyclist safety and address these concerns.”

“In debate, the committee noted the merits of the proposal including design and positive impact it could have for the borough. The committee noted concerns about the suburban location, not well served by public transport, and the presence of difficult junctions in the surrounding area. The committee considered the mitigation put forward as part of the proposal and the extent to which they would address existing issues.”

Minutes

The committee’s decision

The committee granted permission subject to referrals, conditions and a Section 106 agreement, and required all reserved matters to return for future committee consideration.

“Planning Committee 4 February 2026 7 4. The satisfactory completion of a Section 106 Agreement (as set out in the Heads of Terms set out in this report) by 31 March 2026 or a later date as agreed in writing by the Strategic Director of Environment, Housing and Neighbourhoods, and subject to a satisfactory Stage 2 referral to the Mayor of London.”
