He's really are beautiful and inspiring structures. The challenge for commercializing these methods is that they are very hard to get certified and brought up to building codes. When I lived on the big island of Hawaii I have a lot of friends who were building really cool stuff with bamboo but found that when they went to actually get the building permits there were only a few types of joinery which were allowed for actual legal residential or commercial buildings.
