The building is arranged in a boomerang shape along the back hill, with the south side wide open. Walls are built to block the view from the surrounding area, and clerestory windows are placed above the wall, giving an impression as if only the roof is floating. Inside, there is one large open space with boxes that enclose private functions such as toilets and bathrooms located separately. These boxes and the forest of pillars create depth in this casual park-like open space, accepting the habitant’s free activities.
