Very rustic! This is done by using the extra wood that comes off of the tree being cut into a square. You can see the bark is still on. Then it is cut into thin pieces for floor trim. Great re-use of the extra lumber from the log being cut.
Wriggly Tin Shepherd's Huts. The double doors really let the outside in and make the hut feel incredibly spacious. The hut is fully equipped for up to five people. http://tinyhouseblog.com/vardo/wriggly-tin-shepherds-huts/
