It is said that, in a residence at that era, the shinden (the central building) was placed at its center, twin honin halls (main halls) were placed beside it, with one of them on its left (on its east side) and the other on its right (on the west side), and a nanin hall (south hall), another residence, was placed on the southern side of the premises.
当時の邸宅は中央に寝殿が置かれてその左右に東西の対が連なる本院と敷地の南側に別邸である南院を配置していたとされている。
