A two generation residence sits in the suburb of a small city. The client, a musician involved with local music education, requested us a home with a small music hall function. Since the client works in the cement business, a major regional industry, we decided to use concrete as the primary construction material.The rectangular lot is aligned north-to-south, with a river running along the south-east side. The east view towards the river and rice fields beyond it is completely open, while Chikuhou Mountains are visible to the west. The character of the interior spaces differs on each floor. The first floor, which opens onto gardens that run from north to south, includes a large entryway that also serves as a gallery of art works and a living room as the music hall, as well as a dining room, kitchen, and bedroom used primarily by the younger generation. The distinctive curved ceiling distributes the soft light from the skylights into the space. In contrast, the second floor, where the older generation lives, opens to east and west overlooking the river and the rich natural scenery.  Compared to the first floor, the scale is smaller and more enclosed. The tube-shape rooms were designed as places to relax sitting on the floor. Architecture has the potential to become a cultural and social asset. Even residences can go beyond their role as the space for individual lives. Just a few generations ago houses in Japan were used as sites for the ceremonial gatherings that helped to create communities. In this project the space not only enriches the life of the client, but through its function as a concert hall and gallery it becomes a center-point for enriching the entire community.
