Midtown - to call One57 a new development is like calling The Hope Diamond a nice baubble. This is the hottest new building in town. Built by Extell, known for some of the very best new condos in town, this 90-story building has some of the priciest apartments in the city — with the asking price for the penthouse of $110 million — but hey, its almost 11,000 sq.ft. And yes, even in pre-construction, they are getting what they are asking. Unless you’re a billionaire, don’t bother to try even see it, since you must be vetted beforehand (like in, show us your bank).
