I don't really need to add more than what Bill has put so very well...
If one can design a natural/traditional vernacular home from raw materials to a finished turnkey
project (or the supporting craft skills one wishes to be paid for, such as timber framing, plastering, fenestration design/implementation, masonry, etc) without primary or intervening guidance, or needing to be shown how to do something, then they...might be...ready to start a business. If those skill sets are not yet acquired, then they can't really compete and offer competent services for a fee....
I can't really enter into a conversation about, "natural building business," practices if someone doesn't have at least 10 years of experience actually building these structures under good guidance. The current market is getting swamped with too many folks that really are not qualified to run a business. I understand this sounds harsh, yet for example, I just was sent an invitation to a "workshop" of a young man that is claiming expertise in "cobb building." This section of a multi staged
workshop is on stone foundations and methods of building them. This is a turnkey project for a client who is sponsoring the workshop. I didn't even know how to respond to this "request" as the photos of past work was not anywhere near the quality of work that even one of my apprentice would perform, let alone charge money for. This is just one example of so many I come across, or actually get invited into.
I would conservatively state that 50% of the folks "charging" to teach, build and design natural buildings today probably shouldn't be, and/or haven't the base skill sets in architecture to do it as well as it
should be done...
I am open to dialogue, but my standards are those that apprenticing from 14 til 23 in just one of the many required skill sets (timber framing) have instilled in me a sense of "what is"
enough skill, and "what isn't."
Respectfully,
