Georges de La Jungle's paradise, a house made entirely of trees!
Can't have a greener house than this (haha). Seriously, taking 4 years of your life to change part of a forest into a house made up of trees is called a (crazy) visionary. This man from New Zealand very precisely chose this place in the forest where the trees had a certain color so that everything was harmonious. I must say that I was very disappointed to realize that he had not cut the trees into the shape of a house, that there was a metal frame underneath it all. Pfff.
