Paintings of houses go back a long way in British art: the earliest landscape in Tate Britain is a late 17th-century view of an estate in Belsize Park by the inventor of the country-house portrait, Jan Siberechts. The genre quickly became déclassé. By the 18th century Thomas Gainsborough was painting peasant cottages; by the 20th, Algernon Newton had turned his attention to middle-class villas on London’s canals.
