Alexander Gordon Savill was born in Petham, Kent, England on 6 March 1908. His father, Howard Shaw Savill (1872-1953), was a member of the London Stock Exchange. It is not known where or with whom he trained as an architect. It is probable that he studied at the Architectural Association Schools in London.
By the early 1930s he had qualified and in 1933 was elected an Associate of the Royal Institute of British Architects (ARIBA). He subsequently practised in London and in the 1960s worked in the Architects Division, Ministry of Works.
Savill's address was given as 28 Brunswick Square, London in 1939. In 1957 he married Celia Veronica Murray (1920-2009). He died in 1993. His death was registered in Wandsworth, London
In 1967 he converted the Holy Trinity Church in Latimer Road, London into the Harrow Club, a youth and sports club. The church had originally been designed by Richard Norman Shaw in 1887-89. A design for a common room in a woman's hall of residence by him is illustrated in Colour in Interior Decoration by John M. Holmes (London: The Architectural Press, 1931 p. 90a)
