The Manhattan Skyline is a world treasure. Its 1930s skyscrapers, the Empire State and Chrysler buildings give it a silhouette from golden era USA.
However one architectural studio feels New York could do with a rethink. They've proposed a building whose fluid-warped walls and central cavity look as though they have landed on the Hudson, direct from the future.
The latest renderings from Istanbul's Hayri Atak Architectural Design Studio for a proposed high-rise building is unlike anything else on the island. Or anywhere else.
Describing the structure as a "transparent, ghostly stance in the city skyline", the tube-like walls fold through the central hole allowing onlookers to look straight through the "amorphous" building.
