I know this is the first set of plans that the guild has published.
I don't know if you'd call it sanctioned designs or not. They are designs by many different timber frame designers. I don't know who they are until I get the book, but they will have all the contact info in there with each design so you can contact the designer if you need to have them modified for your use, or area.
I believe they have been checked by an engineer or two for loads but I don't know what the limits are. Hopefully the will tell us in the book.
