The hanged treehouse
A treehouse in the forest hanged by three trees.
The solution of using three trees I think is one of the most typical and easiest. Very interesting in this case -even if I don’t like that people punch the tree to secure the structure at the tree- it’s the treehouse construction. Tree beams go from a trunk to the other and each beam is hanged on the tree. The beams are the main structure on which the platform and of course the whole treehouse lay.
