Here is another that is called a tent but that I think is pushing the envelope. This is a semi-permanent structure designed for "glamping."
Autonomous Tents are customizable and can come in two sizes: the 500- to 700-square-foot Cocoon and the 1,000-square-foot Tipi. Sadly, neither one is cheap -- a lot of the cost will apparently go to building the raised deck that these tents sit on. The Cocoon will cost around a hefty $100,000 USD, while the Tipi will ring in at $200,000.
That's no tent. More in TreeHugger: Off-grid Autonomous Tents are made for luxurious camping
