Knight was articled to William Gilbee Habershon and
Edward Habershon (d. 1901) in 1854 and remained for 16 years as Chief Assistant. He became an Associate of the
Royal Institute of British Architects on 17 March 1873 (proposed by T H Wyatt, E Habershon and T Roger Smith) and a Fellow of RIBA on 10 Feb 1879 (proposed by T H Wyatt, W Emerson and T Roger Smith). He was in partnership with
Henry Spalding (1832-1910) from around 1871 and in independent practice from 1878. Costing some £10,000 and opened in 1881, it provided space for concerts and other public gatherings with the occasional use as a theatre. The hall was converted into the Electric Cinema in 1909 with seating for 700, and then further enlarged in 1931 to seat 2,300. The cinema was destroyed by German bombs on 24 April 1941. In 1882-83, Knight designed
The Drill Hall, in
Chenies Street, London, for the
Bloomsbury Rifles, a volunteer unit in which Knight was at the time a captain (and later an Honorary Major). The building is now known as
RADA Studios and is a
grade II listed building with
English Heritage. He also designed a number of private dwelling houses and other buildings in
North Finchley, including the family home during the 1890s,
Netherelms on Woodside Avenue. With
Henry Spalding RIBA he also designed a prestigious villa for a solicitor's family (with connections to the Andrews family of Gainsborough's Mr & Mrs Andrews) called Belle Vue House in Sudbury, Suffolk. Woodside Hall became Woodside Park Synagogue in 1950. Knight directed the £1600 rebuilding of St Andrew's Church,
Hempstead, Essex, in 1887-8; excluding the
chancel,
Harvey chapel and tower. He designed a number of country houses, some for friends, and laid out several suburban estates. He wrote "The influence of business requirements upon street architecture" describing the changes in city buildings that have taken place during the nineteenth century. ==Other activities==
