This is cool! Arborist Brian Cox of Tree Locations has built a tree church that has been completely constructed with living trees in the area of Ohaupo, New Zealand. The outer walls are not real walls, they are made up of living branches and leaves, and that goes for the roof as well! The floor in the inside is made up of grass and mulch. Now a church like this might do well in New Zealand, but try going to a church like this during the hot Alabama summers! I love my air conditioning!
