York House is a historic stately home in Twickenham, England, and currently serves as the Town Hall of the London Borough of Richmond upon Thames.

[4] It then passed through several owners, including (in the late 18th century) Count Ludwig von Starhemberg (1762–1833), the Austrian ambassador to London.

Members of the Johnston family continued to live in the house until 1863, intermixed with tenants such as the Dowager Duchess of Roxburghe (widow of the 5th Duke) until 1837, and William Lowther, 1st Earl of Lonsdale (1757–1844).

[5] In 1864 the property was acquired by two directors of Coutts Bank on behalf of the Orleans Pretender, Philippe, comte de Paris.

[6] The house then remained empty until 1876 when it was bought by Sir Mountstuart Elphinstone Grant Duff (1829–1906), a Scottish MP, junior minister in Gladstone's first government, and from 1881 to 1887 Governor of Madras.

[3] The new council chamber was formally opened by the then Duke of York (later King George VI) in 1926, the same year that the urban district became a municipal borough.
