Thanks to Tokyo based design researcher Jan Lindenberg for this great find: Unusable public seating repurposed as rock garden at Mt. Takao, West Tokyo.
I like the way the temporary, easily movable benches have been made a heavy and (more) permanent part of the surrounds. With growth, this construction will (given a few years and the participation of volunteer plants) probably become an integrated sloping bank, once again ready for sitting on.
Materials: Public Bench
Location: Mt. Takao, Tokyo
