56 Leonard, the latest New York skyscraper, stands at 250 m (830 ft) tall with a ratio of 1:10.5.  This 57-storey luxury residential tower sits in Manhattan’s TriBeCa district providing fabulous views across Manhattan, Brookyln and New Jersey. The cantilevered apartments producing ‘stacked houses in the sky’ proves a unique challenge for our structural engineers on the project.
