As kids, most of us have dreamed of having a treehouse as a haven – a secret place where we could establish a top-secret clubhouse away from our pesky parents. Some of us still do. Interestingly, people in some countries don’t see tree houses as exotic, but as everyday parts of their lives. In New Guinea, for example, the Korowai people live in treehouse buildings permanently. The raised homes help protect their food and belongings from animals and floods by keeping everything above ground level.

Luckily, the treehouses for kids and adults alike have become more than just fairytale-like hideouts or an exotic living places in far-away lands. For those who seek to realize some of their greatest childhood dreams and are looking for a unique way to recharge and relax, architects and designers now offer some unbelievable treehouse hotels for holidays. These have long outgrown the traditional wooden cabin concept, featuring multiple floors or even glass and mirror elements.
