To complement the famous New York City skyline, one team of architects suggests a new "waterline." The bold proposal from nARCHITECTS notes that in order to save neighborhoods at the edge of the water, buildings could be literally be turned upside down and hung from steel armatures, keeping the bottom floors above the waves. This image shows an imagined community in Sunset Park, Brooklyn.

In the team's "New Aqueous City," ground-level parks would be planted with grasses and trees that can withstand occasional flooding, while canals cut into the neighborhood would channel invading waters. According to the architects, the scheme wouldn't just help residents stay above water level, it would also allow for more housing in coastal areas that might otherwise be considered unfit for building.
