With the narrow site area of 37.11 square meters, this project proves that constructing a tower in such a small area is still possible for a residential usage. It is a minimum house for 2 households where mother of the owner lives in the bottom floor and the rest of the family live in the upper floors keeping proper distance mutually.

Cantilever stairs and a colonnade are arranged in the center. Each room spirals the center stairs while going upward gently. The interior space of the 1st floor to the 4th floor sequences as a skip floor.

STEPS succeed in reduction of cost by putting both the exterior and the interior expose pure concrete. Built in the midst of Tokyo, STEPS is designed as a simple urban type residence.
