Free Spirit Spheres are the coolest tree houses I’ve ever seen, big wooden spheres that can be suspended from tree tops or nestle in the crown of large trees.

The largest sphere tree house has a 10′ 6″ diameter and can sleep 4 people (would be pretty cosy I’d expect).Plumbed and wired for microwave, sink and refrigerator it’s got most of the essentials though it does lack a bit on the bathroom front.

You’d normally get to your sphere via a suspended rope bridge and once inside it will gently rock in the breeze, it’s probably advisable not to make any sudden movements once inside.

These do look so cool, however the bad side is the largest sphere has a starting price of $150,000, ouch!
