German design studio, Baumraum architectures, has been designing tree houses for adults [and kids] since 2003. They are real houses built between the branches, thus capturing the best landscape. Each house begins pre-fabricated and sized for a smaller living space explains Andreas Wenning, designer and heart of Baumraum, everything else is customizable; materials for the interior surfaces, furniture etc. The installation is done without damaging the trees. There are no nails or screws that could damage the logs but rather systems such as fabric belts or steel cables that do not impact the branches and allow trees to grow undisturbed. All homes are custom made so the cost depends on the requirements. Tree houses built range from 10,000 to € 120,000, yes euros. Construction time ranges from 3-7 months with the only obstacle being obtaining permits, which are subject to local laws.
The featured tree house below is located in Puglia, Avetrana. The owner lives and works in Milan and wanted to expand their house for rental use: it features 8 square meters of indoor area with views of the surroundings. The interior is a minimal/ modern aesthetic. The wood interior surfaces bode well with the outdoor greenery and the modern furniture with modular pieces work very well in the small space.
