This residential house is introduced from the ambient surrounding and the conditions of site planning. In winter seasons, the strong west wind (the fall wind of Ibuki) blows in this area.So it is the plan of suppressing the load of the building by extending its roof up to the close to the ground soil and fending off cold winds at the roof.In summer seasons, it is the structure that discharges the accumulated heat inside to the outside through the VOID of the inner court and the central VOID installed various parts.
