In Z58 Kuma's architectural strategy is condensed into three main dividing structures: the plant wall, the blade of water and the glass "box".
The plant wall is a linear sequence of steel boxes with a mirror finish containing tiny plants.
The reflections of their surroundings reveal the plants' natural movement. A single opening lets people into the main atrium. 5000 strips measuring 20x20mm form a weave that gives the material a tactile depth perceptible at a certain distance. Another plate of glass captures the presence of the trees in the adjacent garden.
