4/2/2009 - The Helix Hotel in Abu Dhabi’s Zayed Bay doesn’t have floors like we’re used to – instead it spirals in sections of a corkscrew from top to bottom with no clear breaks, flowing from retail to residential, and hotel suites to saunas. The hollow center keeps foot traffic flowing while infusing interior spaces with coastal air and natural light, while on the outside GROW panels are fast at work harnessing solar and wind energy. Because of its unique design, every room has a slighly different view — perfect for watching over the contruction of Zaha Hadid‘s Sheikh Zayed Bridge just next door.
