During the 1640s a change comes over Mansart's style. His buildings become freer in planning, more plastic in conception, and more classical in decoration. This is also the period when he seems to approach most closely the ideals of High Renaissance architecture in Italy, sometimes through direct borrowing, but sometimes apparently unconsciously.
