The Leighton House Museum is an art museum and historic house in the Holland Park area of the Royal Borough of Kensington and Chelsea in west London.
The building was the London home of painter Frederic Leighton, 1st Baron Leighton (1830–1896), who commissioned the architect and designer George Aitchison to build him a combined home and studio noted for its incorporation of tiles and other elements purchased in the Near East to build a magnificent Qa’a (room). The resulting building, completed between 1866 and 1895 on the privately owned Ilchester Estate, is now Grade II* listed. It is noted for its elaborate Orientalist and aesthetic interiors.
