Orleans House

Orleans House was a Palladian villa built by the architect John James in 1710 near the Thames at Twickenham, England, for the politician and diplomat James Johnston. It was subsequently named after Louis-Phillipe, Duke of Orléans who stayed there in the early 19th century. By the early 20th century it was derelict and in 1926 it was mostly demolished. However, parts of the property, including a baroque octagonal room designed by architect James Gibbs, were preserved. The octagon room and its service wing are listed Grade I by Historic England and, together, with a converted stable block, are now the Orleans House Gallery, a gallery of art relating to the London Borough of Richmond upon Thames and neighbouring areas of London.
