John Percival Tate (21 March 1894 – 21 January 1977) was an Australian architect, urban planner and politician. He was born in New Zealand where he trained as an architect and engineer. He moved to Sydney as a young man and went into private practice, later working for the federal government during World War II. Tate served on the Ryde Municipal Council and Sydney City Council in the 1940s and 1950s. As chairman of the Cumberland City Council he was a key figure behind the Cumberland Plan for Greater Sydney. He also served as a Senator for New South Wales from 1950 to 1953, representing the Liberal Party.

Tate was born on 21 March 1894 in Wellington, New Zealand. He was the son of English immigrant parents Frances Lillian (née Gormley or Gumley) and Robert Gillies Tate. As a young man he changed his middle name from "Henry" to "Percival".^[1] After leaving school, he completed an apprenticeship with Panton & Son, a civil engineering and architectural firm in Timaru.^[2]

Tate moved to Sydney in about 1920,^[1] where he went into partnership with William Auburn Young in the firm of John P. Tate & Young. One of the firms earliest commissions was the Manchester Unity Building on Elizabeth Street (later known as the St James Trust Building), which was designed in 1921 and finished in 1924 as one of the city's first high-rise buildings.^[2] Tate "built up a diverse private practice designing aeroplane hangars, theatres and various types of factories".^[1] He also supervised the construction of the Port Kembla steelworks in the 1920s.^[2] In 1923, his firm was selected to design a refurbishment of the Queen Victoria Building.^[3] The Sydney City Council ultimately decided not to continue with the renovations, with Tate & Young suing for breach of contract; they sought £17,448 (equivalent to $794,000 in 2022) but ultimately settled for £7,000 (equivalent to $322,000 in 2022).^[4]

In 1940, Tate joined the Department of the Interior as superintending architect, responsible for defences work programmes in New South Wales. He was appointed state construction manager for the Allied Works Council in 1942,^[2] and advised the Chifley government on housing.^[1] In 1945, Tate was appointed as the inaugural chairman of the Cumberland County Council, established by the New South Wales state government to prepare a planning scheme for the Greater Sydney area which spanned 69 local government areas.^[1] He worked closely with chief planner Sidney Luker to prepare what became known as the Cumberland Plan, which "advocated decentralization, zoning, green belts, open spaces, and improved road and rail systems".^[2] It was presented to the state government in 1948,^[1] but was not formally adopted until 1951. Tate resigned as chairman in protest at its late adoption, which he described as a "civic tragedy".^[2][5][6]

In the mid-1950s, Tate returned to private practice as the principal of John P. Tate and Associates. He also served as chairman of A. E. Goodwin, a shipbuilding and engineering firm.^[1] He was elected as a fellow of the Royal Australian Institute of Architects in 1950 and a fellow of the Town and Country Planning Institute of Australia in 1962.^[2]

Tate served on the Ryde Municipal Council from 1944 to 1948 and was chairman of its housing committee.^[1][7] He was also elected to the Sydney City Council in 1947.^[8][9] He was a leader of the Civic Reform Association, serving as an alderman until 1956. He also served on the executive of the Local Government Association of New South Wales.^[2]

In May 1949, Tate won preselection for the Liberal Party's Senate ticket in New South Wales at the 1949 federal election.^[10] He was elected to a six-year term beginning on 22 February 1950, which was cut short by a double dissolution in 1951. He was re-elected to a three-year term at the 1951 election, but was defeated for preselection by Ken Anderson prior to the 1953 half-Senate election.^[1]

Tate married Gladys Woodland (née Farquaharson) in 1920, with whom he had four sons. After being widowed in 1974 he remarried in 1976 to Bernice Cheetham. He moved to Canberra in the same year and died at Canberra Hospital on 21 January 1977.^[2]
