Roger Westman (born 1939) is an English architect perhaps best known for his designs of social housing in London.
Westman was educated, on a scholarship, at Latymer Upper School in Hammersmith and the AA.
In 1981, Westman exhibited his scheme Walls: A Framework for Communal Anarchy at the Institute of Contemporary Arts, London. His exhibition was described by the Arts Correspondent at the Times as "a marvel" and by the London Evening Standard as "almost irritatingly understated... genius."
He was a close friend of Sir John Summerson, until Summerson's death on 10 November, 1992. Summerson had been a tutor of Westman's at the AA - and they shared a fondness for architectural history.
Westman is a long-time member of the Twentieth Century Society and has been involved in the restoration of many important buildings designed and built in the twentieth century.
