Plants pop through small holes in the die-cast aluminum panels that punctuate the living facade of Green Cast, a mixed-use building in Odawara, Japan.

Designed by architects Kengo Kuma & Associates, the building’s slightly slanted panels are formed over decaying styrene foam, creating organic-looking vertical planters over the structure’s entire surface.

Concealed behind the panels, equipment such as watering hoses, air reservoirs for ventilation, and rainwater catchment downpipes service the green wall and the rest of the building.

The building offers basement parking and provides two floors for offices and a vocational school, while a fourth floor houses a two-bedroom residence with access to a private rooftop terrace.
