A three-story residential and office building. The exterior is a steel portal frame that shows the structure as it is. The site is shaped like a shoe with different widths on the north and south sides, and the plan is distorted to reflect the shape of the site. In order to realize slender columns for the 12.3-meter span of the floor, the joints between columns and beams are pin joints that are free to rotate.
