Manhattan developers keep building skyscrapers taller and taller, but Greek architect Ioannis Oikonomou hopes to break a new kind of record.

His firm, Oiio Studio, has designed a U-shaped tower called the "Big Bend" that aims to become, what Oikonomou calls, "the world's longest building" (if you were measure from end to end of the U, which would total approximately 4,000 feet).

The design calls for a super-tall, skinny skyscraper bent in half, to form what looks like the first drop of a roller coaster. From the sidewalk to the building's peak, it would stretch about 200 feet taller than One World Trade Center, the largest tower in the city.
