Modern houses built anywhere, even underground in a burrow or cave. How, for example, this wonderful in all senses and covered with a 15 thousand square feet in the sandstone house in Festus (Missouri, USA). Built by Curt and Deborah Sleeper (Curt and Deborah Sleeper), is an underground building is completely modern interior (which can be seen, looking at photos in the continuation), which fits into the natural "stone wall".
This is an incredible example of architecture with low power consumption - a cave not need to heat or air-conditioned. Unfortunately, the wife Sleeper during the crisis have lost ownership of this house, and now he may be on eBay at a starting price of $ 300 000.
