Horace George Turner was born in Brighton, Sussex, England in 1881 and was articled to John W. Rhodes (1860-1943) in London from 1897 to 1900. He also attended the Architectural Association Schools in London, Regent Street Polytechnic and Thornton Heath Polytechnic. He worked as an assistant to Edward Crosse (1842-1916) in 1902, to Leslie William Green (1875-1908) from 1902 to 1905, and to Charles Edward Barry (1855-1937) from 1907.
Turner commenced practice as an architect in Thornton Heath, Surrey in 1909 and in 1913 relocated to Westminster, London. In 1920 he left England for China to work for the British architectural firm Hemmings & Berkeley in Hankow. He remained with them until 1928 when he moved to Sydney, Australia to work for architectural firm Hennessy & Hennessy. He left the company in the early 1930s, after which he appears to have worked alone in New South Wales.
He passed his professional exam as an architect in 1909 and was elected an Associate of the Royal Institute of British Architects (ARIBA) in 1910 and a Fellow of the Royal Institute of British Architects (FRIBA) in 1925.
