I think every young child's dream is to have their own treehouse. Now thanks to baumraum, you can have a modern tree house of your own. So far they have done some in different regions of Germany as well as in Austria, Hungary, Italy, Czech Republic, Switzerland, Brasilia and in the USA. Not a fan of the modern look, they also do traditional tree houses.
What if you don't have enough cash to create one, well they are in the process of having tree house hotels to stay at. So get ready to become a kid again with some sweet hide out spots.
