The concept of a desert city sounds like an oxymoron, but when you think about it, the desert offers a limitless supply of a pretty useful though underrated building material -- sand. The architects at XTU are fully aware of this, and have come up with an interesting concept dubbed Flohara.
While the concept is referred to as a desert city of sorts, it's really more a cluster of sand shelters rather than a large urban environment. The shelters consist of lightweight, inflatable and easily transportable bubbles that can created locally or created elsewhere before being transported. The bubbles would be sprayed by a mixture of water, sand and hydrogel before being left in place for the sand and sun to work together to solidify the structure.
As the world's population expands, we're going to have to get creative to find shelter solutions for people. Flohara makes for interesting conceptual food for thought
