An apartment building for 9 families in a suburban residential area. Taking advantage of the low-density district, the building has many exterior dwelling places. The three-dimensional mass with several void spaces was designed using wind simulation. The exposed structural wooden frames are not only supporting the floating mass but also working as exterior furniture. The annexes in the ground floor would be used as a space for non-residential use, such as home office, lecture class etc so that their life would be connected to the surroundings.
