This site is located in the base in Tanzawa mountainous region and is the quiet environment dotted with a field and a private house. But new Tomei Expressway will plan to pass through the neighborhood the near future, and therefore the thing by which this quiet environment turns big is expected. This housing includes 3 courtyards. I thought the courtyard form to adapt to a change in the situation of the entourage and the future environment current as of such. The 1st floor is a square plane of 1 side 13.65m (7.5 ken) which includes 3 courtyards. The scenery which is seen from the living room put on the center of the 1st floor won't change in the future. The top of the mountain (Nino tower and three NO tower) assumes a posture on the axis over the north garden. A wall in a south garden excludes something unnecessary and cuts only the sky off in a background in a garden. There is also another spot garden facing the bathroom. The 2nd floor of gabled roof is mentioned at a floor plane of 15.47 m (8.5 ken) by 3.64 m (2 ken). I also succeed to my concept of "the breathing house " this house and am aiming at the healthy house production down which a natural wind floats.
