Fascinating Living, Growing Architecture

Still-living plants can themselves be shaped into bridges, tables, ladders, chairs, sculptures - even buildings. Known variously as botanical architecture, tree sculpture, tree-shaping, tree-grafting, pooktre, arborsculpture, and arbortecture, the craft is, essentially, construction with living plants.

Grown from the roots of a rubber tree, the Khasis people of Cherapunjee use betel-tree trunks, sliced down the middle and hollowed out, to create "root-guidance systems." When they reach the other side of the river, they're allowed to take root in the soil. Given enough time a sturdy, living bridge is produced.
