He went into partnership with a series of other architects over the course of his career, including John Richard Schomburgk Evans,[a] Charles Alexander Russell, and Rolfe Vernon Boehm.
[4] Milne was articled to the Adelaide architect Alfred Wells[b][6] from 1903 to 1906, being taught there by chief draftsman Stuart Clark.
[9] In October 1928, architects Milne, Evans, and Russell submitted their plans for extensions and alterations to the Crown & Anchor Hotel in Grenfell Street.
[13] In 1933-4 Milne travelled to Europe on a study tour, and was impressed by Georgian architecture, especially that of John and James Adam.
The design of the Victor had considerable impact on future new cinemas, both in modern architectural expression and with its planning for both sightlines and acoustics in the new era of talkies.
[16] Later associates in his practice, from the late 1940s onwards, included L. C. Dawkins and Rolfe Vernon Boehm (1946); Russell Stuart Ellis (1947); F. P. Bulbeck (by 1957); J. R. N. Twopeny (1960); and James Hodge (by 1964).
[4] He also played Australian Rules football, tennis and golf, and excelled at swimming and diving, earning trophies in these as well as rowing.
[4] Milne semi-retired in 1957, but continued to undertake alterations to buildings designed by him, and some work for old clients until he finally retired fully in 1973.
The scholarship, now worth A$20,000, is awarded to the selected "graduates of the Master of Architecture to travel and undertake study abroad and then return to Adelaide".
[20] In 1928-9 Milne (then in practice as F. Kenneth Milne, Evans & Russell) designed and supervised construction of an office building at 47-49 Waymouth Street, Adelaide, for Norwich Union Fire Insurance Society, which included ground floor offices for the Commercial Bank of Australia.
[21][22][23] The building was officially opened on 5 June 1929, after a dinner the previous night attended by many local dignitaries.
