John Nash was one of the foremost British architects of the Georgian and Regency eras, during which he was responsible for the design, in the neoclassical and picturesque styles, of many important areas of London. His designs were financed by the Prince Regent and by the era's most successful property developer, James Burton. Nash also collaborated extensively with Burton's son, Decimus Burton.
Nash's best-known solo designs are the Royal Pavilion, Brighton, Marble Arch, and Buckingham Palace. His best-known collaboration with James Burton is Regent Street and his best-known collaborations with Decimus Burton are Regent's Park and its terraces and Carlton House Terrace. The majority of his buildings, including those that the Burtons did not contribute to, were built by James Burton's company.
