This isn't your ordinary hobbit hole in the ground; even Mr. Underhill would be jealous of this cozy underground home! No heating or A/C is necessary because this home's temperature is self-regulating. This first floor welcomes you into a great room, comeplete with a seating area, dining, and a kitchen. Below, enjoy a "walk-out" basement, complete with hot tub and an open view of the night sky. You may be living below ground, but you'll feel like you're in heaven! #SMChallenge21 #Shell
