For those who have everything: The O2 Treehouse

last updated 10 January 2015

The treehouse has “reached new heights,” thanks to architect Dustin Feider. A few slabs of wood slapped together can’t compare to one of his O2 Treehouses. These “giant, floating” geodesic domes are constructed from wooden polygons, which distribute the weight across the entire structure. They’re hung by a cable suspension system, so the orbs not only move with the trees but also don’t require a single hole to be drilled into their “leafy host.”

Price: Starting at $20,000
