During the Heian period aristocratic dwellings were built in a symmetrical style known as shinden-zukuri. During the Muromachi and Momoyama periods, this shinden-zukuri style was supplanted by new, more practical styles of architecture, leading to the development of shoin-zukuri, of which the Katsura Imperial Villa is an excellent example. Further developments led into the sukiya-zukuri style, found in the dwellings and tea houses of the Edo period, which was the basis of modern Japanese dwelling-house architecture.
