This week David Adjaye unveiled an upside-down skyscraper

This week on Dezeen, Adjaye Associates proposed a supertall skyscraper in New York that has a series of cantilevers to give it a dramatic, inverted appearance.
Adjaye Associates, which is led by architect David Adjaye, designed the 1,663-feet-tall (498-metre) skyscraper for a vacant plot in New York State in response to an open Request for Proposals from the state government.
