The son of the architect William and his wife Mary, Segar Owen was born on 6 October 1874 and educated at Warrington Free Grammar School (1884). He was articled to his father, William Owen (1850–1910). In 1894 he became a student member of the RIBA and in 1895–6 he worked for G. E. Street while attending the Royal Academy Schools. He passed the qualifying examination in 1896 and was elected Associate of the RIBA on 30 November 1896, proposed by A E Street, R P Spiers and J Belcher. Returning to Warrington Segar Owen joined his father in partnership under the style of “William and Segar Owen.” He was elected Fellow of the RIBA on 8 January 1906 proposed by W Owen, A E Street and R P Spiers. Following his father’s death in 1910 he continued the practice under the same name, taking his brother Geoffrey into partnership in 1912.
About 1911 Segar Owen adopted the Welsh tradition of combining a Christian name (frequently Wyn) and common surname, e.g. Wyn-Davies. Unfortunately, Segar Owen lacked sufficient names thus becoming Segar Segar-Owen. This appears to have coincided with his association with Anglesey where he became High Sheriff.
Segar Owen died on 21 December 1929 at the Lindens Nursing Home, Hutton near Brentwood, Essex.
