Architecture firm proposing to build ‘world’s longest building’ – a curved 4,000 ft long skyscraper

A very unusual, record-breaking skyscraper could be coming to New York

As skyscrapers soar to new heights, a New York architecture firm is taking a different approach, proposing a U-shaped tower that would smash records as the longest building in the world. Designs for the "Big Bend" show a 4,000-foot long arched skyscraper that would tower over Manhattan's Billionaires' Row - an area named for its ultra-luxury residential high-rise buildings.
