Takayuki Matsumoto (Mutsumi Architects & Associates)

Pillars in Japan architecture are the key to space composition, and a pillar determines the quality of a space. The order of the square pillars, in proportion, forms the structural core and forms the entire building, which contains the four-story void. The structural key pillars that are intentionally removed create psychological instability within the stability, characterize this space. The wooden tower, which has a vertical spatial area, replaces the Itakura wall with structural plywood wall, expressing the prototype of a wooden architecture.
