A Beijing-based architecture firm named Penda has designed a treehouse made from bamboo that doesn’t use any of those things. This design instead requires ropes and rods of bamboo, and nothing more. It was such an impressive and revolutionary concept that it won second place at the 2016 A’Design Awards in the architecture design category. Even if it hadn’t won, it’s certainly impressive!
Attempting to be environmentally friendly, the treehouse would use recycled bamboo from the area. The individual rods are then arranged to form the joints. Eight rods form what the team calls a “knot,” which would be used to create interlaced walls.
The floors are made in the way you would expect, with bamboo rods being lashed together to form a continuous and flat layer for walking on. The whole design is modular, meaning extensions could be brought in from off-site and added to the structure. This is how the treehouse could form.
