These Genre-Busting Tree Houses From Germany Start at $6K

Dubbed the Nut Room, this darling tree house sited in the backyard of a terraced property in Germany was inspired by the old yet vital oak tree that anchors the connected terrace. In order to expose the host tree to as little strain as possible, the team built an independent static system for the structure. The house was prefabricated off-site before being lifted over the main residence with a large mobile crane during the assembly.
