There’s just something about the design of the incredibly efficient mathematical tent known as the geodesic dome that has always intrigued us. While we’re not currently in the process of opening our own hotel, Fugu Hospitality is making geodesic dome cabins for hoteliers looking for unconventional hotel solutions, but they’re also available for the rest of us looking for high-end accommodations in the open air. So what, exactly, can you do with a geodesic dome cabin outside of using it as a cabin? Turn it into a writer’s retreat. Use it as a gym, or as a spa or as a lounge area. Each one of the modular structures is customizable depending on your needs, so whether you’re buying one of twenty, Fugu will build a solution for you. Pricing starts at around $28k, but since every aspect of the dome is customizable except the frame itself, the sky’s the limit when it comes to build out.
