The Dutch House stands on the undercroft of a 16th-century brick building, restored to Robert Dudley in 1558. Samuel Fortrey, who leased the site from 1619, erected the present house in 1631. The article names no architect and calls the style Artisan Mannerist, with Dutch gables. It was a royal residence from about 1728 to 1818.
George III built a Castellated Palace nearby around 1800, designed by James Wyatt, with possible input from the king. Its initial 40,000 pound allocation reached 500,000 by 1811. It was brick, stuccoed to resemble stone, and the Old Queen's House was demolished to make way for it. A replica 17th-century Dutch garden was added in 1969.
Historic Royal Palaces, an independent charity, runs it. It reopened to visitors in April 2006, and it is Grade I listed.
