8 Hidden Underground Homes That Prove Life is Full of Surprises (4 of 5)

6. Hesse, Germany

Tucked into the countryside of Bad Zwesten, a small glass dome rising from a grassy knoll conceals a remarkable living space. A therapy house once upon a time, these days it serves as a cozy Airbnb rental home for vacationers. The temperature inside is naturally regulated thanks to the home being constructed from age-old construction clay, while glass windows at the dome’s peak let sunlight brighten up the rooms. When you enter, you’ll discover a 16-foot-high ceiling that opens to a round, multifunctional room framed by arches that have been cleverly repurposed as bookcases, seating areas, and cabinetry.

7. Cundinamarca, Colombia

When you first look at this hobbit-style dwelling, you are convinced you’ve been whisked into Middle-Earth. Not only is it embedded in a lush hillside like in the JRR Tolkien novels, it even features the same iconic round wooden door and colorful stained glass that Frodo Baggins would have lived in. Situated in the wilderness of central Colombia, this one-bedroom, one-bathroom home is another Airbnb rental. There’s a skylight above the bed, a bubbling hot tub on the wooden deck in which to eliminate all your stresses, and even an organic garden where guests are welcome to try the fresh produce. The rustic furnishings complete this charming abode. Second breakfast will become part of your normal routine after staying at this hobbit house.
