"[Terunobu Fujimori's flying mud boat] traveling tea house installation is the newest addition to his repertoire of fantastical designs. simply put, an acorn-like mass blown up to human scale is suspended on tension cables over four natural wooden posts anchored into the ground, and only accessible by ladder. the concept is in itself quite dynamic, capable of being installed in any environment and any climate, and although it is only big enough for a few people, the idea could be used as a case study for the practical application on a residential scale in places where being elevated off the ground would serve as an advantage."
