This house was designed with the intent to provide a single optimal and calm environment by means of a large external court as a common space for the family, and as a shared element for all spaces within the house. The courtyard occupies 1/3 of the site area and divides the first floor. A single-story universal living/ dining/ kitchen space was situated to the south of the court and to the north, a two-story building with three private rooms. Through spatial connections above the courtyard, the entire residence becomes one continuous unit. The structural columns of 35mm-by-125mm steel flat bars were set at an interval of 600mm and afford a sense of transparency whereby any part of the residence is visible through views that extend beyond the court.
