of English architecture, as Campbell's work was in a strict Palladian style. The aesthetic preferences of Campbell and Burlington, soon joined by the aesthetic style of their close associate William Kent (who worked on interiors at Burlington House), were to provide the leading strain in English architecture and interior decoration for two generations. Campbell's work closely followed the form of the previous building and reused much of the structure, but the conventional front (south) façade was replaced with an austere two-storey composition, taking Palladio's Palazzo Iseppo di Porti in Vicenza for a model but omitting sculpture and substituting a balustrade for the attic storey. The ground floor became a rusticated basement, which supported a monumental piano nobile of nine bays. This had no centrepiece but was highlighted by venetian windows in the projecting end bays, the first to be seen in England. Other alterations included a monumental screening gateway to Piccadilly and the reconstruction of most of the principal interiors, with typical Palladian features such as rich coved ceilings. The Saloon, constructed immediately after William Kent's return from Rome in December 1719, has survived in the most intact condition; it was the first Kentian interior designed in England. Its plaster putti above the pedimented doorcases were probably by Giovanni Battista Guelfi. Lord Burlington transferred his architectural energies to Chiswick House after 1722. Upon Burlington's death in 1753, Burlington House was passed on to the Dukes of Devonshire, but they had no need of it as they already owned Devonshire House just along Piccadilly. The fourth Duke's younger son Lord George Cavendish and a Devonshire in-law, the third Duke of Portland, each used the house for at least two separate periods. Portland had some of the interiors altered by John Carr in the 1770s. Eventually Lord George, who was a rich man in his own right due to having married an heiress, purchased the house from his nephew, the sixth Duke of Devonshire, for £70,000 in 1815. Lord George employed Samuel Ware to shift the staircase to the centre and reshape the interiors to provide a suite of "Fine Rooms" en enfilade, linking the new state dining room at the west end to the new ballroom at the east end. Like Carr's work, Ware's was sympathetic with the Palladian style of the house, providing an early example of the "Kent Revival", a particularly English prefiguration of Baroque Revival architecture. In 1819,
