Kasa House is a minimal residence located in Aichi, Japan, designed by Katsutoshi Sasaki + Associates. In this plan, a large roof was used to loosely connect the surrounding environment with the internal space and living activities. Four eaves are arranged with a garden around it, while dining and living space intervene part of the garden. Each room takes in light and wind from two adjacent gardens. In addition, each garden is given different uses such as outdoor living, approach, kitchen garden, and laundry, but it is assumed that the use and landscape will change according to the life such as the growth of children in the future.
