The structure "Casa 3 alamos" (House of 3 poplars) is based on an flexible system, what is following the movement of the three trees in the wind.
Two platforms where contructed, each one suported by the 3 trees. One as the floor, the other as the roof of the treehouse. The walls are build by recycled doors which are sliding in double-T columns with no fixing, which would limit the sliding movement. The parallel columns all around the tree-house can follow the movement of the wind easily.
