Do you think tree houses are just for kids? You are totally mistaken. It’s true that they are often designed and used as an outdoor playroom for children but there are some amazing ones like miniature apartments where you can escape from the city life and spend your weekends. There are both cheap and more luxurious tree houses available for different needs and purposes. Some designs are so gorgeous that we’d define them house in a tree rather than a tree house. All in all, you should see our gallery of the best tree house designs and let us know which one is your dream house in the comments.
