An “arboreal architect” named Dustin Feider is designing upscale tree houses for the rich and famous in Los Angeles. Many of the tree houses are based on the geodesic dome which was first made famous by the futurist Buckminster Fuller. The average cost for one of Feider’s tree houses is $20,000. Because of the structure of the domes, they are relatively light and are hung from the tree’s branches with cables. The tree house materials are also fully sustainable. For more information, see Dustin Feider’s O2 Treehouse website and this YouTube video on the construction of one of these tree houses:
