Until 1978, the Home Office had its offices in what is now the Foreign and Commonwealth Office Main Building on King Charles Street, off Whitehall. From 1978 to 2004, the Home Office was then located at 50 Queen Anne's Gate, a Brutalist office block in Westminster designed by Sir Basil Spence, close to St. James's Park tube station. Many functions, however, were devolved to offices in other parts of London, and the country, notably the headquarters of the Immigration and Nationality Directorate in Croydon.
