Constructively the building is complex, especially at the time of construction, since the balance that is wanted to create between the levels is difficult to achieve until the reinforced concrete of which they are formed is not hardened. Cellular polycarbonate panels are used for the exterior walls, which protect the exterior while allowing light to pass through, without interfering with the privacy of the house. The floors are made of polished concrete with radiant heating for thermal comfort, and the steel stairs without risers do not interfere with the horizontal views and allow one to see through them.

Description of project by Ippei Komatsu Architect
We decided to excavate the site step by step and create two new low retaining walls on the site. We build the house on top of a new retaining wall, and an "L" shaped wall is erected on top of the new retaining wall and the floor is placed on top of it. In this way, repeating this strategy, another "L" shaped wall is placed again keeping the balance, and on this floor another floor level, and so on repeatedly.
By stacking the symbolic walls that make up the entire structure, on the upper floor, where they are kept in balance, the objective is to create a relationship between each of the levels and the surrounding environment.
Local materials are used and the typology of the houses in the area and the views that could be had from this elevated position, from which we can see the Todaiji Temple and Mount Wakakusa which are about 8km away, are taken into account.
1- The design is based on the use of the retaining wall that we can find in the buildings in the area as they are located on quite uneven terrain. The walls rise randomly, always maintaining the structural balance of the retaining wall.
2- As the structure is like a yajirobei (traditional Japanese toy, based on balance), it is very unstable until the concrete solidifies completely, so it was complicated to build the structure.
3- Reinforced concrete structure and steel structure. The wall is made of hollow translucent polycarbonate.
4- An open floor plan has been achieved with an exterior wall on the inside.
