Love what you bring up here. I'm familiar with the LBC and have been around some of the building that took part in it. Beautiful stuff folks are creating within such strict guideline.
You're right, we have the knowledge, skills and capacity to do A LOT better on the planning side of human existence and design that we currently are. Thanks for your input.
In part, it has been a materials problem. Up until recently, it was much cheaper to build using "standard" materials that didn't really allow the flexibility to create solutions that matched the location and the people. Now that is changing. We have a greater understanding of biology to see that nature builds things in much different ways than we do, and with 3D printing, we are seeing the material that will give us the flexibility to do the right thing without worrying about the price.
All designers, whether they be artists, architects, or engineers, should have a biologist at the table, because nature knows how to build pretty much anything!
