Transforming a historical site for a global leader in cancer research and treatment 

The Royal Marsden is one of the largest cancer centres in Europe and a global leader in research and bench to bedside medicine. The Trust operates on three sites – Chelsea and Cavendish Square in central London and Sutton to the south east of the capital. JCA are working with architects Stanton Williams on the design of a major new building on the Fulham Road campus, having won an invited design competition. This new Centre will enable the Trust to significantly expand its surgical, inpatient and research capacity, extend its Imaging, SACT and Endoscopy services and create an innovative integrated diagnostic centre. It also presents an extraordinary opportunity to make fundamental and long-term changes to the existing estate and deliver an integrated environment for research, diagnosis, treatment and rehabilitation for those living with, in remission of, and beyond cancer.


The design strategy is, as always, based on the necessity of a creating a healthy building, the primary importance of daylight and the complete integration of clinical and the architectural design. The Chelsea campus is one of the most densely developed hospital sites in London within the tight street pattern of one of London’s most affluent boroughs. The design meets the planning challenges which this poses with a development strategy that addresses the site’s complex requirements for decanting, demolition, enabling works and the constraints it imposes on construction. The proposed building is an elegant and simple solution that overcomes these complexities to provide an excellent environment for patients and staff.


The design team will begin the detailed design stage in March 2024.
