Luminair Tree Tent
It's a tent in the literal sense of the word — its 16oz waterproof cotton canvas skin makes it so — but that doesn't mean you'll be dragging the Luminair Tree Tent (£6500 and up; roughly $10,000) around with you. Instead, think of the structure as a semi-permanent tree house. Thanks to a hybrid aluminum and steam-bent ash frame, the entire tent, including floor and bunks, weighs just 264 lbs., despite being able to handle an additional 550 lbs. of load. At 3 meters in diameter, it's not huge, but it's certainly big enough for two adults and provides an interesting option for above-ground shelter in the wilderness.
