The houses in the Green Village are not built according to architectural plans. A scale model is created: 50 to 1. The designers/architects work with the client to achieve the desired result...same process as a regular house, but many, many changes are made as they build. When they see the opportunity to do something unique, they jump on it. Money appears to be little object at the moment.
They call the side cuts of the bamboo, bamboo bones. Here's a couple of chairs in our house.
