Always wanted to do the Swiss Robinson thing? Here's your chance -- with the Free Spirit Spheres.

Though made to be hung from trees as shown, like a tree house, these huge spheres can also be placed on a cradle on the ground. Four attachment points on the top of each sphere and another four anchor points on the bottom are each strong enough to carry the weight of the entire sphere and contents. The Sphere's skin is made of two laminations of wood strips over laminated wood, and the frame is waterproof, so it can exist in any kind of inclement weather .

This isn't your father's treehouse: it can sleep up to 4, has a countertop stove, a sink, and refrigerator, with complete plumbing (does that mean it has a bathroom?; they don't say).

The Hand Crafted Wood/Fiberglass Sphere is wired for 20 amp, 120/240 volt AC.

What will one of these luxury treehouses cost you? $120,000 big ones for the top o' the line.

Get your order in soon: Free Spirit Spheres has commenced limited production of the 3.2 metre fibreglass sphere tree houses and now has sphere shells (US$6,300+) and kits (US$35,000+) available for the DIY market.
