The Kazue Residence is a wooden single-story, partly two-story house with a basement. Built in 1939 in Kugahara, Ota-ku, Tokyo, it has a Spanish-style exterior but an authentic sukiya-style interior, blending both Japanese and Western architectural styles.

Despite being built during WW2, the high-quality materials used in its construction and the excellent craftsmanship of the builder has allowed this sukiya-style residence to retain its original appearance without major alterations to the interior or exterior. The architecture, including the Kouseki-an tearoom and the garden, which were later additions, shows many different faces from season to season.
