This area has a peculiar atmosphere of openness. Signboards and plant pots are put on the street and there are many long-term residents, who are often seen chatting around the street.This site is like a “special valley spot of the zoning regulation”. A zoning change line (Commercial district to Housing district) is designated near the southern border line of the lot. So, the house can be built slightly higher than the neighboring one in this site. Under such surroundings, a two-story wooden house is built. The 1st floor which connects to the street for creating living space linked with lively outside, and the 2nd floor is taken a physical distance from the busy street and its floor slab is lifted higher than the neighboring eaves for taking enough sunlight into the 1st floor. In winter, the kamakura-shaped hill with a bathroom inside can store solar heat collected through a large window allocated upper south part on the 1st floor. It can also be functioned as various living goods such as a sofa when watching TV, a verandah when sitting from outside with a window open, a screen from the entrance, a storehouse and a play place for children.Bedrooms of the 2nd floor are minimum size so the 2nd floor hall is used for all activities such as study or reading other than sleeping. From the 2nd floor window, an above roof view completely different from the 1st floor opens up.This spatial composition linked up a series of motions in a house with the movement of wind, heat, users and goods may only be called “two-story wooden house” at present. However, I think it is different from the usual one because there is no appropriate name for this composition at present.
