New York City real estate is booming. Beyond charts and graphs and stats, another way to gauge the strength of the market is by the sheer number of new developments launching sales or leasing in a given season.

Spring 2014 was action-packed, as was the fall of 2014. And the spring of 2015 looks to be no different, with at least 40 different projects hitting the market in the coming months. As the mercury on the thermometer climbs, so too does the degree of hot hot heat in the real estate market. To prepare for the onslaught of pricey condos and rentals about to flood the city, all we can say is: brace.

DDG is the developer, construction manager, general contractor and design architect of this very gray building. Sales launch in early spring — read: soon — and when complete, will contain 13 duplex, full-floor, and half-floor condos. Amenities in the boutique building include a fancy-sounding private gym (“with reclaimed wood flooring, exposed brick masonry and board-formed concrete”) and bike storage. Some apartments will have private elevator access, roof access, terraces, and storage.
