Looks good. Piece in Piece, or more locally that would be referred to as a Red River building here. How did you make the long groove for the wall logs? What kind of joint will you use between the hewn timbers in your walls?
I've been looking at a system similar to yours recently. You were talking about a wall cavity filled with shavings, then a double plank siding. How is this done? Is it just board and baton with boards instead of batons?
