The house is located in the city of Sapporo, capital of Japan’s Hokkaido island. It comprises two distinct spaces-Small House and Large Terrace. The former was designed as an inexpensive yet highly insulated space with a very small footprint. It features a private room on the second floor which functions as a hiding place.

The 26-square-meter (280-square-foot) Large Terrace has a dual relationship with the interior. It acts as its extension which makes the small house feel more spacious, while making it thermally compact at the same time. The architects designed the building as an extension of the traditional domestic spaces in Hokkaido which take advantage of the thermal insulation provided by soil and feature centrally positioned sun rooms.
