Ocean levels are rising around the globe, so rather than tethering our buildings to the sinking shoreline why not suit them for a life at sea? That’s the approach behind the Water-Scraper, a futuristic self-sufficient floating city. A special mention in the eVolo Skyscraper Competition, the design expands the concept of a floating island into a full-fledged underwater skyscraper that harvests renewable energy and grows its own food.

Touted as a self-sufficent floating city, Sarly Adre Bin Sarkum’s Water-Scraper utilizes a variety of green technologies. It generates its own electricity using wave, wind, and solar power and it produces its own food through farming, aquaculture, and hydroponic techniques. The surface of the submerged skyscraper sustains a small forest, while the lower levels contain spaces for its inhabitants to live and work. The building is kept upright using a system of ballasts aided by a set of squid-like tentacles that generate kinetic energy.

The architects “envision a future where land as a resource will be scarce; it is only natural progression that we create our own. Approximately 71% of the Earth’s surface is ocean, even more if climate change has its way, hence it is only natural progression that we will populate the seas someday.” As anyone who has seen Waterworld will attest, it’s a grim future indeed — which is why it’s essential that we do what we can to stem the course of the world’s rising tides.
