 The new Baroque fashion, and that of Palladianism which quickly followed it, swept away the double pile concept of one compact block with sets of rooms back to back as at Belton in favour of houses having at their centre a grand corps de logis flanked by long wings or pavilions, which in Palladio's original conception had been the mere farm buildings of what were small country villas.These wings became adapted in design to house the staff, and other secondary rooms.A second distinguishing feature of this new era was that flat lead roofs now often replaced the former attics where the servants had slept.
