Finsbury Health Centre

"Finsbury Health Centre is the finest monument to nascent clinical provision in Britain and a brilliant piece of planning; it is very important for its break with the tradition of municipal architecture, its flexible plan and up-to-date construction techniques. It was viewed as the prototype on a national level for modern construction and communal architecture such as NHS clinics, and health and treatment centres."
