Dream big. Really big. The New Orleans Arcology Habitat, or NOAH, totals 30 million square feet and will stand 1,200 feet high. The design by E. Kevin Schopfer combines architecture and ecology – hence “arcology” – to create a massive floating city for flood-plagued New Orleans. As a compliment to local ongoing water retention measures, NOAH will create a water-filled basin in which it will float, as well as a multi-cavity hull that will serve as its actual foundation. The floating city will include 20,000 residential units for sale and rent, three hotels, 1,000,000 square feet of commercial space, public works, local and express elevators, cultural facilities, a school district, and sky gardens, among other things.
