Edward Box Wetenhall was born in Stoke Newington, Middlesex, England on 21 November 1870. He was articled to Henry Thomas Gordon (1845?-1922) and Edward John Lowther (1846?-1900) of Gordon & Lowther in London from 1888 to 1892 and remained with them as a draughtsman until c.1900. He qualified as an architect in 1893 and later that year was elected an Associate of the Royal Institute of British Architects (ARIBA).
His address was given as 40 Walton Street, Kensington, London in the 1901 England Census. In 1902 he he moved to Canada and by 9 January 1903 had opened an office in Calgary. Within months of this he formed a partnership with James Llewellyn Wilson (1856-1931) as Wilson & Wetenhall. The collaboration was very brief and the partnership was dissolved in late 1904. Although the partnership lasted less than a year, they designed several buildings in Calgary and Manitoba [see the entry on James Llewellyn Wilson in the Biographical Dictionary of Architects in Canada 1800-1950]
By 1907 Wetenhall had returned to London and in that year is recorded as having an office on Sackville Street. By 1912 he was back in Canada and that year the Greater Vancouver Directory of 1912 lists him as having an office on Abbott Street, Vancouver. Only one building from his second stay in Canada is known - The Hill Block, a commercial building in New Westminster, British Columbia, built in 1912. By 1914 he had returned to London. The Kalendar of the Royal Institute of British Architects gives his address as Wyken, Woodside, Wimbledon, London in 1914 and 1922; 27 Sackville Street, Piccadilly, London in 1919 and 1920; and 38, Parliament Street, London in 1923 and 1936. It is not known if he returned to Canada after 1914. He appears to have retired by 1939.
Wetenhall was elected a Fellow of the Royal Institute of British Architects (FRIBA) in 1924. He died in Eastbourne, East Sussex on 26 April 1962
