Second floor’s volume was rotated to 14 degrees from the main building axis, thus interstitial spaces between the rotated wall and the outer wall turned into voids. The skylight was positioned in the upper section of the void, allowing natural light to enter the family room in the first floor. Moreover, one of the rotated is also inclined on the vertical plane, and the part which overlaps the stairs is raised up, and resembles origami or a facet.
