We’ve written about floating airports, and there are reports of man-made floating islands to fight rising sea levels. But floating skyscrapers? That’s what Malaysian designer Sarly Adre Bin Sarkum suggested at this year’s eVolo Skyscraper Competition, which seeks to find “outstanding ideas that redefine skyscraper design through the use of new technologies” and “change the way we understand architecture and its relationship with the natural and built environments.” Click through our gallery of the remarkable structures that won special mentions and prizes, with designs ranging from vertical prisons to buildings made of steel nesting to towers that filter the air around them.
