Thank-you Emmet!
You hit the nail on the head in my search of information when you wrote about Xypex. This is good stuff and practically priceless, at least in my view.
I am interested in your negative water well comment. Since I will need irrigation for crops what do you recommend? I can drink, clean, and cook with the rain water. I am especially interested in how Timber Frame cubes can be connected together at a future date, technically speaking (and with green technologies from a fundamental and advanced perspective).
Feel free to pile on the information that is rarely understood or available from the internet because, I have hammered most every green topic available as you have suggested with your hints.
