A big pipe sticks out from the valley. It totally focuses like a telescope while looking around the opening scenery. Makinohara plateau that lined with a tea plantation and houses along a gentle slope spreads out here. Here is nice and full of nature. I felt that it is necessary for client who has lived long there to find the way of building which could realize charm of this land again.While investigating surroundings and sites thoroughly, I began to think what kind of house suitable is. At first, this site consists of tiered stone wall. Also, it was a land slide prevention area and under the cliff regulation. That’ s why I was limited and was not able to use the whole site for the construction. Therefore, I constituted pipe-formed second floor part.The plane constitution of this pipe is a trapezoid. Because the view of the room to the north is beautiful, the foot spreads out towards the north. I made a big opening for the north side.This opening projects only scenery. In addition, it catches the change of the season and daily weather directly. Talks with a person and the scenery are born there. Not only the opening project scenery, but also it brings rich light and wind. Simple space constitution makes the room comfortable.Furthermore, I made internal space and an outside border with the space vague to plan harmony with the scenery. I groped for the constitution of the details part not to insist on to realize it. I enabled it by making facilities and storing and opening simple.There is nice and full of nature in local area. What are the natural environments that are rich for us? It will be the environment where nature is opposite the building which we live in equally and obediently. There is the richness that we can realize by tying human and the nature through architecture.
