In Paul's most recent podcast (with Maddie Harland), they discuss the relative merits of green vs dry wood construction. Maddie makes the point that Ben Law, noted UK woodsman, builds his polewood houses with fresh cut
trees, which then shrink while drying. That shrinkage causes them to tighten up around the pegs and joints, making for a more stable structure (also known as a "cruck frame"). You might want to read up on Ben Law's roundwood construction techniques to see how he deals with these issues. Ben Law is a GENIUS and inspiration, what a fascinating man and a wonderful way to make a living.
Paul makes the point that green wood is HEAVY.
