 Overview of the project: A tree house built in the bamboo grove within the school grounds.
 You enter the field through an entrance gate made of bundles of growing bamboo, then cross a single-bridge balance beam, then a suspension bridge, and into a house made of woven bamboo called the "Time Zone." Beyond that, you can slide down a slide that leads to the bamboo forest.
