Living, dining and study are concave, while the private areas convex. Service spaces such as kitchen, laundry and service bedroom are separated, and placed on the perimeter of the apartment. The wall changes from one side to other, providing a variety of nooks and recesses for bathrooms and storage spaces. This arrangement allows service areas to be embedded into the wall, leaving spaces uncluttered. Within the wooden element there are three bedrooms, walking closets and bathrooms.
