屋敷 (yashiki) is a Japanese compound of 屋 (ya, "house") and 敷 (shiki, "a laid-out site"), whose parts point to a house and the grounds around it.

In everyday Japanese, this word often sounds grander and more formal than the ordinary word for home, so it commonly evokes a large or old house with grounds.
