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/
This doesn't look to difficult to build...love the idea of divided sections for easy access to different size logs. I would make it bigger & have it outside on my covered lanai though ...don't want possible bugs in the house.
