I have thought of this before and always concluded that it would work well. I would think with rot resistant
wood, and a fairly level, if not gently sloping site would work well with a rubble-filled foundation system. But for building it itself, it leaves the builder with (2) bird mouth joints on the bottom cord, then a tennon joint at the peak, truss completing a vert strong triangle shape. Using 8 x 8 foot timbers, a person could easily span 12 feet due to the lack of snow load, making a 36 foot long building out of only (4) bents. Assuming the golden ratio was used for building width, that would be a 24 x 36 foot building. A person could then use Steel or wood structural panels for the roof to get a super high R-factor.
About the only issue is with the design itself in that it is limited on light and floor space due to the A shape design. David and Jeanie in their book "Cabins" overcame this with a design that had a dormer of sorts running down both sides of the A frame to allow for more headroom and window placement. It would mean more carpentry and joinery of
course, but considering its benefits, may well be worth doing. I felt it was, but peoples opinions may differ.
