Peter Francis Nigel Miller [commonly known as Peter F. N. Miller] was born in London, England on 8 May 1924. He trained as an architect part-time at Canterbury College of Art in Canterbury, Kent from 1940 to 1942, and, after military service, from 1947 to 1950. He qualified as an architect in 1950 and was elected an Associate of the Royal Institute of British Architects (ARIBA) in 1952.
From 1950 to 1952 he was employed as an assistant at the industrial design firm Gaby Schreiber & Associates. He then worked in the London office of Hugh Casson (1910-1999) for two years before setting up his own architectural practice in London in 1954. In 1956 he formed a partnership with William "Bill" Tritton in Chelsea, London. In 1965 Miller and Tritton merged their practice with that of Donovan Cole Purcell (1913-1973) to form Purcell Miller Tritton. They also opened a second office at 64 Bethel Street, Norwich, Norfolk. Over time the practice opened further offices in Britain and in 2012 was rebranded as Purcell.
Miller was elected a Fellow of the Royal Institute of British Architects (FRIBA) in 1968. He was also a Fellow of the Society of Industrial Artists and Designers (FSIAD).
Miller's address was given as Bridge-Bean Road, Kent in 1924; 325, Richmond Hill, Richmond, Surrey in 1952; 9 Sydney Street London in 1959; and Old Hall Farmhouse, Swanton Novers, Melton Constable, Norfolk in 1968 and 1972. He died on 12 June 1997. His death was registered in North Walsham, Norfolk
