With an improving local economy driving strong sales in Queens and a large supply of competitively priced units heating up the Manhattan market, it was an interesting year for condo sales in 2015. Bisnow previously featured the top 10 sellers for Manhattan, Queens and Brooklyn, but here’s a look at the best performers city-wide for last year, compiled with data from PropertyShark.

10. Fifty Third and Eighth

Developer: HFZ Capital
Neighborhood: Hell’s Kitchen
Address: 301 W 53rd St
Units Sold: 50
Median Sale Price: $1.5M

In late 2013, the units in this 348k SF building were converted from rentals to condos. The newly refitted building is being billed as a slice of “true New York character in the heart of Manhattan” by the developer, with most of its “affordable luxury” units going for $3M or less. Sales opened in January of last year. 

9. Halcyon

Developer: HFZ Capital
Neighborhood: Turtle Bay
Address: 305 E 51st
Units Sold: 76
Median Sale Price: $2.5M

This modern 32-story building features a total of 123 luxury units, with amenities like an indoor gym, a swimming pool, a yoga studio and a Rainbow Room-esque communal Sky Lounge. 

8. 388 Bridge

Developer: The Stahl Organization
Neighborhood: Downtown Brooklyn
Address: 388 Bridge St
Units Sold: 88
Median Sale Price: $1.3M

Brooklyn’s tallest tower affords its residents sweeping views of the Manhattan skyline and the surrounding borough. The condo-rental hybrid has 234 rentals and 144 condo units, with all the amenities you’d expect from a Manhattan high-rise, like an indoor gym, a media room, a rooftop viewing deck and a communal lounge. Easy access to 11 different train lines makes commuting into Manhattan a breeze.

7. The Aston

Developer: Cord Meyer Development
Neighborhood: Forest Hills

Units Sold: 89
Median Sale Price: $845k

The luxe units in this striking Queens tower are distinguished by designer kitchens, spa bathrooms and spacious, well-lit living rooms. Amenities include an indoor gym, an outdoor terrace and on-site parking. 

6. 540West

Developer: Fortis Property Group and Wonder Works Construction
Neighborhood: Hell’s Kitchen

Units Sold: 86
Median Sale Price: $1M

This project spans the full block of 48th and 49th streets and consists of two seven-story buildings separated by a 6k SF courtyard. Units top out around $3.5M. Nearby developments like the Durst Organization's pyramidal 625 West 57th St promise to fuel a development boom in the area that'll have major staying power. 

5. River and Warren

Developer: Centurion Real Estate Partners and Five Mile Capital
Neighborhood: Battery Park City
Address: 212 Warren St
Units Sold: 82
Median Sale Price: $2.6M

Another rental-reborn-as-condo conversion. In this project, 324 rental units became 164 luxury condos, as well as a fitness center, a playroom and a rooftop park. 

4. 325 Lex

Developer: Carmel Partners and Times Square Construction & Development
Neighborhood: Murray Hill
Address: 325 Lexington Ave
Units Sold: 77
Median Sale Price: $1.3M

The original design for this 123-unit building, drawn up by Studio Dror Architects, called for a series of offset glass boxes stacked vertically. That plan was nixed sometime in 2013, replaced with a design by H. Thomas O'Hara where part of the building is cantilevered over an adjoining low-rise apartment building.

3. North Shore Towers

Developer: Sigmund Sommer
Neighborhood: Glen Oaks
Address: 27240 Grand Pkwy
Units Sold: 112
Median Sale Price: $610k

Built in the early '70s, this three-building luxury co-op features a total of 1,800 residences framed by rolling lawns and an 18-hole golf course. The three towers are linked by a shopping arcade that includes dining, shopping and even a movie theater.

2. One Riverside Park

Developer: Extell
Neighborhood: Lincoln Square/Upper West Side
Address: 50 Riverside Blvd
Units Sold: 85
Median Sale Price: $2M

This building bore the brunt of the "poor door" controversy in 2014 when plans were announced that showed it would have a separate entrance serving its 55 affordable units.

1. Island House

Developer: Hudson Cos and Related Cos
Neighborhood: Roosevelt Island
Address: 551, 555 and 575 Main St, Roosevelt Island (technically part of Manhattan)
Units Sold: 166
Median Sale Price: $310,595

Existing residents of this former Mitchell-Lama development can buy a rehabbed unit at a steep discount—in the ballpark of $200 per SF. As part of a program to keep Roosevelt Island affordable, folks who buy through the discount program and later sell can only sell to moderate-income buyers who'll also be paying under-market rate. Market-rate units are also offered as part of a redevelopment by Hudson Cos and Related Cos.
