Eco-architecture has been around for quite some time already since the call for battling global warming begins. It is so overwhelming seeing those people giving our environment particularly the trees some importance. It is our way of giving back to them the goodness and comfort that they gave us. The people behind Abitalbero are just a few who are into eco-architecture. They have created numerous tree houses and all of them are completed with respect to the environment as part of the team’s philosophy to make you experience the feelings when you were a child. I am sure; every one of us had experienced climbing up that one tall tree in our backyards.
