A reconstruction in Tokyo of Koive, originally inspired by the trembling leaves of Finnish birch trees.  In Finland, the work incorporated wind and low, extended northern light entering through open windows. These environmental conditions formed part of the structure itself. In the Tokyo version, exhibited at TOKAS Hongo, such conditions were absent, and the structure was redesigned accordingly. Perforated metal straps maintain form through tension and deflection. Instead of responding to wind, structural tension becomes visible. Unlike the diffused northern light, the controlled interior lighting of the city emphasizes shadow and reveals subtle variations in surface and form. As the environment changes, so does the phenomenon. The work accepts these differences, seeking a new equilibrium between structure and surrounding conditions.
