For the redevelopment of Churchill Gardens in Pimlico, west London, Powell and Moya planned a series of eight-storey blocks in which each flat had a view of the river. Still acknowledged as one of the most outstanding post-war housing developments, it was selected in 2000 as the ultimate winner of all Civic Trust awards over their 40 years.
Powell Moya and Partners went on to design a series of public buildings, including universities and hospitals, nearly all of them acclaimed for their humanity and elegance. Its last major work was London's Queen Elizabeth II Conference Centre, completed in 1985.
The practice won the Royal Gold Medal for architecture in 1974, and Powell was knighted the year after. In 1997, the firm was taken over by Pringle Brandon Architects.
