Peter Dunham, Widdup & Harrison [also known as P. Dunham, Widdup & Harrison and Dunham, Widdup & Harrison] was an architectural partnership formed by Peter Browning Dunham (1911-1997), Frank MacFarlane Widdup (1918-1985) and Michael Charles Harrison (1916-2002) in Luton, Bedfordshire, England in c.1948.
Two two four-bedroom homes at Harpenden, Hertfordshire, designed for J.E. Willies and J. Mawle by Peter Dunham, Widdup & Harrison are briefly discussed in 'Decorative Art' 1955-56 (p.18).
Other projects by the firm included a house at Studham, near Luton in Bedfordshire (1953); a bungalow near Whipsnade & the Dunstable Downs, Bedfordshire (1954); a factory for Allen & Hanburys in Ware, Hertfordshire (1957); an out-patient centre in Stevenage, Hertfordshire (1962); and offices and factory complex for Hawthorn Baker Ltd. in Dunstable, Hertfordshire (1963)
It is unclear when the partnership was dissolved. By the 1970s Widdup and Harrison were partners in another practice, Charter Building Design Group in Ampthill, Bedford and Luton. This partnership was dissolved in stages between 1972 and 1974
