Sir Arnold Joseph Philip Powell (15 March 1921 – 5 May 2003[1] in London), usually known as Philip Powell, was a ground-breaking English post-war architect.
He was educated at Epsom College and then the Architectural Association.
He was the father of "Humane modernism", and is famous for designing the Chichester Festival Theatre. He also designed the Skylon, the Churchill Gardens apartment complex in Pimlico and the main House at Chichester.
He founded a practice with Hidalgo Moya, Powell & Moya Architect Practice. Peter Skinner joined the practice in 1948 and later became a partner. They won a competition to build Churchill Gardens, Pimlico, a complex that houses 5,000 people in 1,800 flats. They were aged 24 and 23 respectively. They were then invited by Frederick Gibberd to design a housing project in Harlow New Town. Northbrooks sits imposingly above a valley to the South of the town centre, affording good views from and to the four-storey slab blocks. However, arguments with Harlow Design Corporation over the use of flat roofs led to the pair terminating their involvement prior to completion. They undertook no more work in the town, much to the disappointment of Gibberd, who had lectured them at the Architects' Association School.
They designed the Skylon Installation at the 1951 Festival of Britain, which sought to instil a sense of positive feeling at a time of postwar depression.
Powell designed a Putney school, St Paul's School (London), a number of Oxford and Cambridge University buildings including Wolfson College, Oxford and at Christ Church, the courtyard at the Museum of London and Chichester Festival Theatre.
In 1974, Powell and Moya became the first to win the RIBA Gold Medal for architecture as a Practice.
Powell was knighted in 1975 after years of dedicated work as a member of the Royal Fine Arts Commission.
