The City of London Planning and Transportation Committee (CLPTC) has granted planning consent for the new Maggie's Centre at St Bartholomew's Hospital in London.
The idea behind the cancer centre at St Bartholomew's Hospital was proposed by Barts Health NHS Trust to enhance the quality of care for cancer patients across north-east London.
Located next to the Great Hall, the Maggie's Centre will improve welfare access and facilities in the area.
The centre was designed by Steven Holl Architects and Donald Insall Associates, and includes a three-storey urban townhouse with full open space and light, and a roof garden with flowering trees.
Maggie's Centre will also feature a new garden designed by Christopher Bradley-Hole that will be open to patients, staff and the public.
Maggie's CEO Laura Lee said: "We very much welcome the Committee's decision and are truly thankful for all the support our scheme has received.
"We look forward to working closely with Barts Health NHS Trust to bring the highest quality cancer support to people across north-east London and working in partnership with the hospital to support the long-term restoration and preservation of the historic North Wing."
Barts Health NHS Trust CEO Peter Morris said: "The building of a Maggie's Centre at St Bartholomew's Hospital marks an important step in our strategy to strengthen the position of Barts in the City as a world-class cancer centre combining excellence in clinical care, research and patient experience.
"We welcome the resolution to grant planning for the Maggie's Centre along with the approval of our own application. This will be an important first phase in our vision to restore the historic North Wing and establish a heritage quarter."
