With 145 (!) closings in 2016, the Rudin-developed, FXFOWLE-designed Greenwich Lane was the biggest-selling building of the year. It took a while for the development, rising on the former St. Vincent's Hospital in the West Village, to get to this point: sales launched in 2013, and the first closings began at the end of 2015. In that time, it's smashed sales records, welcomed celebrity residents, and—as of the beginning of 2017—only a handful of units at the multi-building complex remain.

Sales launched at the Oosten, Piet Boons über-fancy Williamsburg condo building, back in 2014; and with 100 units that closed in 2016, it's the second-best-seller of the past year. Among the pricey units that have sold are one of the building's penthouses, which closed for $6.6 million—a neighborhood record. One of its townhouses recently hit the rental market with an absurd asking price of $18,000.

Though it's less high-profile than some of the other developments on this list, Brooklyn's Navy Green, located at 8 Vanderbilt Avenue, holds the no. 3 slot with 92 units closing in 2016. (But considering the larger development near the Brooklyn Navy Yard will have a staggering 433 apartments when completed, that's maybe not such a high number.) And unlike pricey developments like the Greenwich Lane or 432 Park Avenue, the median price for an apartment within the development was (relatively) affordable, at $423,256,

Rafael Viñoly's skinny supertall may not have had the most closings in the past year—it claims the no. 5 spot, with 81—but it did have the priciest apartment sold in 2016: a 96th-floor pad that closed for a whopping $87.6 million back in September. 432 Park Avenue began closings at the end of 2015, and the median price for an apartment there in 2016 was $18.442 million.

Developer HFZ Capital converted a former rental building in Hell's Kitchen into condos in 2014, with sales launching in 2015. That strategy paid off, with 76 of the building's units entering contract in 2016. The median sales price for those apartments was just over $1.6 million.

Chetrit's so-called "lightsaber building" at 135 West 52nd Street saw about half of its 109 units go into contract in 2016, with a median asking price of approximately $3.2 million. The illuminated 48-story tower launched sales in 2014.

Closings at Robert A.M. Stern's Financial District tower, 30 Park Place, only began over the summer, but it's already racked up 55 units sold in that time. Among the units sold is a $34 million penthouse, which developer Larry Silverstein snagged in the fall. The median sale price for these units is, unsurprisingly, slightly higher, at about $5 million; some of the units have also already appeared as super-pricey rentals.

Rounding out the list is another building by Naftali Group, known as the Seymour. Another Hill West Architects building, this particular project has 49 units, 48 of which went into contract in 2016. The median sale price is $2.4 million.
