The website for Zaha Hadid's swooping condos along the High Line just transitioned from a staid teaser to a full site that showcases a handful of new renderings while touting everything from the building's finishes to its next-level amenities. (Sorry, no floorplans just yet.) The changeover signals the quiet sales launch of one of the most anticipated projects in the city. This doesn't mean it's time to hunker down and obsessively refresh StreetEasy; although the condos at 520 West 28th Street are officially up for grabs, their listings will be guarded by Corcoran Sunshine and doled out only to those who directly inquire. In other words, they're not private, but they're exclusive.
