Japanese architectural style of mansion-estates constructed in the Heian period (794–1185).
The form consisted of a shinden (central building) to which subsidiary structures were connected by corridors. The shinden faced south on an open court, across which was a pond garden. The eastern and western tainoya , or subsidiary living quarters, were attached by watadono (corridors), from which narrow corridors extended south, ending in small pavilions. This layout resulted in a U-shaped arrangement around the court. See also shoin-zukuri .
