In response to the swathe of supertall luxury residential towers rising in New York, local studio Oiio has proposed a conceptual skyscraper that loops over to boast length rather than height.
The Big Bend would be formed from a very thin structure that curves at the top and returns to the ground, creating what the architecture firm describes as the longest building in the world.
Oiio, based in New York and Athens, came up with the proposal to highlight the race for height between Manhattan's luxury condo developers.
Real-estate companies are capitalising on a planning law that permits them to purchase air rights from neighbouring buildings, allowing for taller and taller towers on relatively small plots.

"The story of The Big Bend follows a recent trend that has appeared in New York City: the emergence of myriad tall and slender residential skyscrapers," said the studio. "New York City's zoning laws have created a peculiar set of tricks trough, which developers try to maximise their property's height in order to infuse it with the prestige of a high-rise structure," it continued.
"But what if we substituted height with length" What if our buildings were long instead of tall""
Renderings show The Big Bend among the luxury apartment towers proposed and under construction on and around West 57rd Street, just south of Central Park, which has become known as Billionaire's Row.
