#15 – Cave House
This house is crazy and funny because it was entirely built inside a cave. You can find this funny home in Festus, Missouri. The Festus Cave House was built by a couple called Curt Sleeper and Deborah Sleeper.
The couple who built this house claims that they have wanted to live in complete privacy so they decided to build a house inside a rock. Their house is luxuriously furnished and is built on three stories. The best part about living in a house such as this one is that you would be protected by every force of nature, such as strong winds and tornadoes.
