Danish starchitect Bjarke Ingels' giant tetrahedron on West 57th Street, which he has designed for the Durst Organization (yeah, that Durst Organization), is one of the more interesting and talked about new buildings currently under construction in New York City. Recently, Ingels let Bloomberg inside the unfinished building for a video tour, during which he explains his reasons for designing the building in its highly unusual shape, calling it "the lovechild of a courtyard building and a skyscraper." He goes on to say, "When you take the typical European courtyard building, daylight and sunshine can come down. When you give it the density of a skyscraper, it will be too dark, so by making it massively asymmetrical, we can actually create something where the courtyard actually gets sunlight and daylight and views ... It's definitely the first time we've done a building that is geometrically a hyperbolic paraboloid."
