The h2O scraper is a conceptual multi-dwelling building that would float with its top level on the surface of the sea, and the rest dangling down into the water below
As cities become more densely-populated, the trend for multi-dwelling complexes has been to build up – hence the advent of the highrise as we know it today. Building down doesn’t seem to be much of an option, as it would be very labor-intensive, and residents would justifiably freak out at the thought of living hundreds of feet below the surface of the Earth. Malaysian architect Sarly Adre Bin Sarkum, however, has proposed a multi-level building that goes down – into the ocean. While his hO2+ concept is pretty unlikely to ever be built, the imagination behind it was enough to merit a Special Mention in eVolo magazine’s 2010 Skyscraper Competition.
