Tree houses, treehouses, or tree forts, are buildings constructed among the branches or next to the trunk of one or more mature trees, and are raised above the ground. Tree houses can be built for recreation or permanent habitation. Generally, the term "tree fort" is used only for recreational structures and not permanent homes. A lot of kids dream to have a tree house where they can play, but this dream is not always possible especially for those who live in big cities. Anyway for those who want a collection of amazing tree houses like the one in the picture bellow you can see a great tree houses on Freshome.
