Planted, living cherry tree. This is what was said about it. Talk about thinking long-range! Swedish architects at VisionDivision worked with Italy’s Politecnico di Milano, planting 10 Japanese cherry trees to grow into this retreat! Time frame? 80 years! The team tied thin rope around the plants, bending them towards a temporary structure in the middle, then plans to use pruning, grafting, and other techniques to grow this “hourglass” retreat!
