An invitation-only competetion was recently held where many eminent architects pitched in their concepts for the Helix Hotel in Abu Dhabi's Zayed Bay. Leeser Architects won the competetion and here is their winning design. A peculiarity of this concept hotel design is that 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 design promises to make maximum use of renewable sources of energy like sun, wind, and ocean water while keeping guests comfortable in all 208 rooms. We have featured other hotels too at Home-Designing. See the interiors of Burj Al Arab & Hotel Atlantis.
