7 Houses You Won't Believe People Actually Live In

3) Extreme Tree-house:

This tree house is just one example of the typical house used by the Korowai tribe of New Guinea, who were totally detached from the outside world and had no idea about the existing world until 1970.  Normally people build tree houses 10 feet above the ground but, these Korowai tribes build their real tree houses 165 feet above the ground. They build such houses to avoid predators, floods and ant swarms. You can imagine a tree house up in air just looks outstanding and provides breathtaking views.
