The site is kasai-city Hyogo. The site is on a busy road. It is difficult place that a building is open toward south. Therefore, I have thought of point as admitting light into the room except south. I have thought that make size of building smaller as much as possible, and I have made the appearance of house a one-story building. I have thought that this house was built big slope roof. This house glazes corner of the ceiling at a slant. I have planned admitting sunlight and outside green into there. Thus, there is open space by that sunlight. This house have been used a tile and a board of Japanese cedar fifty-fifty for the material of one floor. The earth floor is the training room for host avocation, and is disposed kitchen and bath room due to making a functionable space. This floor was used a board of Japanese cedar was living room, and I have thought this space makes comfortable space.
