6 unbelievable underground homes

  • You don't have to be a Hobbit or a super villain to live underground.

    In fact, the U.S. Department of Energy says earth-sheltered houses require less outside maintenance, are sometimes less expensive to insure and can have lower energy costs in environments with extreme temperatures.

    Some architects like the challenges underground spaces pose and see them as great opportunities for innovative design. Other homeowners, like millionaire John Z. Blazevich, like the idea of building below the surface because there is a lot more space. There are even people who enjoy recycling abandoned spaces, like public restrooms and missile bases, and turning them into livable dwellings.

    Take a look at these six unique subterranean properties that may inspire you to start digging.
