House-K is a minimalist house located in Sapporo, Hokkaido, designed by Yoshio Yamauchi Kei. This two family dwelling includes a grandmother family of four, and two children in elementary school. Each dwelling unit is made so that the families can live with independence, each having their own entrance while living in a shared space. A parking garage is provided in a separate building to protect the privacy of the first floor. Space between the housing portion and the garage forms a small courtyard for the grandmother.
