In places like Dubai, water is scarce, and sand is everywhere. As skyscraper construction continues to boom in the city, there is a greater need for sustainable building techniques more than ever. To combat this problem, five innovative Chinese designers have proposed the idea of using material from the surrounding landscape to construct a "Sand Babel."
Qiu Song, Kang Pengfei, Bai Ying, Ren Nuoya, and Guo Shen imagined massive towers built entirely out of sand, using a solar-power 3D printer. The structure would resemble a mushroom rock, jutting high above the horizon, offering tourists sweeping views of the desert. Additionally, the mushroom top would harvest water, formed from condensation. Though their idea is a mere proposal, it won them an honorable mention in eVolo magazine's the 2014 Skyscraper Competition.
