Like so much in Jared Kushner’s world these days, all is in flux at his onetime sure thing and real-estate crown jewel, 666 Fifth Avenue, in Midtown Manhattan.

The 41-floor skyscraper, between 52nd and 53rd Streets, has new owners, Brookfield Properties, the powerful, publicly traded Canadian real-estate company; a less Satanic new address (660 Fifth Avenue); and, in a few years, thanks to starchitects Kohn Pedersen Fox, it will have a new look, replete with a new façade, a sparkling lobby, and terraces overlooking Trump Tower. All things considered, it’s just as well. The building has always been a bit star-crossed by its former street address as well as by the unlucky 13 years that it was owned and operated by the Kushner family of New Jersey.
