Perhaps no other city talks about real estate as much as New York, and residential conversions continue to be the talk of the town. Escalating prices, evictions, and displacement have become the norm, while building new places to live for New Yorkers and newcomers has never been more difficult. As ground-up multi-family construction remains sluggish in many Manhattan and Brooklyn neighborhoods, developers and owners are increasingly turning to conversions to capitalize on the housing crunch and ameliorate the weakened demand for other uses.
The past two years have been a busy time for legislation to help turn offices into much-needed housing. In April 2024, New York State's housing budget included a new tax incentive for office-to-residential conversions. On a city level, one component of Mayor Adams' "City of Yes for Housing Opportunity," approved at the end of 2024, was the streamlining of zoning bylaws to help speed up office-to-residential conversions. Most recently, a newly released report from the City Comptroller's office found that the first wave of office-to-residential conversions could yield over 17,000 new housing units (h/t 6sqft).

The Flatiron Building, July 2025 (CityRealty) | https://www.cityrealty.com/nyc/flatiron-union-square/flatiron-building-185-fifth-avenue/187971
Major office-to-residential conversions underway include the McGraw Hill Building in Midtown West (224 rental units), the former Pfizer headquarters at 235 East 42nd Street (1,600 rental units), and 5 Times Square (1,250 rental units). Office-to-residential conversions have heavily favored rentals, but some of the city's most prestigious prewar buildings have gone condo in recent years. These include One Wall Street, the Woolworth Building, the Broad Exchange Building, the forthcoming conversion of the The Flatiron Building, and the recently announced conversion of the Emmet Building.
Given the city's consistently hot residential market, conversions haven't been limited to office buildings. Hotels such as the Waldorf-Astoria on Park Avenue, the Standish in Brooklyn Heights, and The Surrey on the Upper East Side have turned fully or partly residential, and plans to convert the Watson Hotel in Hell's Kitchen were also recently announced.
Other commonly converted buildings include schools (555 West End Avenue), hospitals (The Greenwich Lane), warehouses (The Shephard), publishing houses (Armorie), parking garages (220E9), and houses of worship (Novare).
Additionally, some developers opt to convert their rental buildings to sales units. Conversion plans for Upper East Side rental The Strathmore were announced earlier this summer, and other recent examples include 212 West 72nd Street, The Perrie, and 450 Washington Street.
Storage facilities haven't come up as often, but at least one is on the horizon: 139 Franklin Street, in the heart of the Tribeca West Historic District. A joint venture between Broad Street Development ("Broad Street") and TPG Angelo Gordon ("TPG") purchased the building from the Sofia family, which operated it as a self-storage facility, for $43.5 million in July 2025. Broad Street and TPG's portfolio includes 40 Bleecker Street in Noho and 215 Sullivan Street in Soho, the latter of which is a combination of the circa-1892 Children's Aid Society Building and a newly constructed expansion. Tribeca Citizen notes that this will be the first in a series of properties that will be redeveloped under a new Broad Street Bespoke brand.
139 Franklin Street (Broad Street Development)
139 Franklin will overlook the Finn Square and its beautiful surrounding architecture
139 Franklin Street dates back to 1909, when it was designed by Maynicke & Franke for importing business Strohmeyer & Arpe Company. It rose on the former site of the Gothic Revival-style Fourth Associated Reform Church, and quickly attracted attention for its ornate terra cotta facade and neo-Renaissance elements. Interiors are distinguished by 13-foot ceilings and oversized windows, which will be appealing in a residential conversion. Additionally, Broad Street CEO & Principal Raymond Chalmé observed that its history as a storage facility means it has strong floors.
In the city's historic districts, conversions are more likely since changing the building's use and altering interior spaces does not need the approval of the Landmarks Preservation Commission ("Landmarks") unless the interior is a designated landmark. However, demolitions, additions, and any exterior work would need Landmarks' permission. The spaces created from these conversions vary widely but are often less formulaic and cookie-cutter than new ground-up residential construction. Successful historic conversions tend to attract buyers who are eager to live in unique spaces and own a piece of the city’s history.
This renegotiation of space is also what makes conversions so difficult and costly for many buildings. Deep floorplates where interior spaces are far removed from windows, redesigning a building's plumbing and HVAC, and the position of a building's stair and elevator cores have made many office-to-residential conversions unviable.
As the city and state further rethink policies to encourage more residential conversions, below we revisit the 20 best new development condo conversions in the city and their most intriguing units on the market today.

Following the passage of the 2019 rent laws, 51% of tenants in a rental must agree to buy their apartments before a condo or co-op conversion can take place, as opposed to the previous 15%; as such, few such conversions have taken place in recent years. However, permits for 393 West End Avenue's conversion were filed just before the new laws took effect.
Described as "a sleeping giant on West End Avenue" by conversion architect CetraRuddy, the project included Landmarks-approved exterior modifications and the creation of expansive new floor plans. Interiors feature restored tray ceilings, white chevron oak floors, LED lighting, open chef's kitchens with Naica quartzite countertops and Miele appliances, marble-clad primary baths, and in-unit washer/dryers. Residents arrive to an attended lobby and enjoy such amenities as a Great Room with courtyard access, a fitness center, an enchanted forest-inspired children's playroom with courtyard access, a teen gaming lounge, and a Club Lounge with fully equipped bar.

When the Broad Exchange Building was completed in 1902, its close proximity to the New York Stock Exchange made it one of the most valuable office buildings in New York. Over 100 years later, at a time when a hybrid work model shows no sign of fading, the Clinton & Russell-designed building's Italian Renaissance facade was carefully restored during the conversion to residential, and its proximity to the neighborhood's first Whole Foods, Battery Park, the Seaport, and an increasing number of restaurants and conveniences makes it even more attractive.
All units feature open-plan layouts, high ceilings, premium finishes, and ample storage. Over 8,000 square feet of indoor and outdoor amenities include a fitness center, multi-sport simulator, children's play area, residents' lounge, and roof terrace with outdoor kitchen and beautiful views.

The Wales
Originally opened as as the Hotel Chastiagneray in 1900, and located in what is now the Expanded Carnegie Hill Historic District, The Wales was designed by architect Louis Korn in the neo-Renaissance style and presents an uplifting stone-trimmed Roman brick facade and a lavishly-detailed entryway with a marble-stepped staircase. The hotel's name changed several times over the decades, but was known as the Hotel Wales when Adellco bought the building in December 2018. It quietly closed a year later and gave the last guests pieces of the hotel's historic memorabilia.
Much to the relief of local preservationists and architecture aficionados, historic details like terra cotta window surrounds, terra cotta joints, and the brick and limestone facade were restored to their former glory amidst the Landmarks-approved conversion to a condominium. The most noticeable change is a new cornice and penthouse with a wraparound terrace and roof terrace.
The penthouse sold for $18.5 million in September 2024. Like all other units, the penthouse has interiors by Cabinet Alberto Pinto as well as access to amenities like an attended lobby, fitness center, and pet grooming station.

One Hundred Barclay Tribeca is a pre-war landmark located at the junction of the Financial District, Tribeca, and Battery Park City. Designed by Ralph Walker, dubbed “Architect of the Century” by the American Institute of Architects, and completed in 1927, the building was one of the city’s first Art Deco skyscrapers. The opulent Jazz Age lobby is one of the finest in all of New York. In 2015, the tower’s upper floors were retrofitted as sprawling loft residences with high ceilings and high-end finishes. Residences begin at 170 feet above street level, and rise from there, featuring ample light and views from the Hudson River to the Midtown skyline. One World Trade Center rises across the street and comes into direct, dramatic view from south-facing apartments.
One Hundred Barclay boasts over 40,000 square feet of amenities that include a 24-hour doorman and concierge, a fitness center designed by The Wright Fit, an 82-foot lap pool with adjacent children's pool, and spa and treatment rooms. The club level on the 18th floor offers a billiards room, a club lounge with bar and dining room, a children's playroom, a teen lounge, a media lounge, a wine tasting room, music practice rooms, and four outdoor terraces. The building also offers bicycle parking and private storage and five-minute walking access to the shops at Westfield World Trade Center, Fulton Center, and Brookfield Place, as well as the parks and waterfront promenade at Battery Park City.

555 West End exterior (Credit Joel Pitra of DDreps)
555 West End Avenue is a masterwork of pre-war, Collegiate Gothic architecture. The red brick facade is adorned with white stone trim, quoin window surrounds, owl gargoyles, crenellated turrets, and other touches that lend the building a majesty at once bespoke and magical. The school’s unique features figured beautifully into its 2019 conversion to condominiums. Soaring ceilings and tall windows are as well-suited for classrooms as they are for high-end living. A stately sidewalk moat lends an equal degree of privacy and separation from the sidewalk for classrooms and condos alike. The arch-windowed library became an atrium-like living room with a second-floor viewing gallery in a 3,463-square-foot Library duplex. At the top, the vault truss-roofed basketball court transformed into a spectacular Solarium penthouse, lit by a massive skylight and a sheer window wall that opens onto a 37-foot-long private terrace.
The conversion also introduced luxuriant features such as a round-the-clock attended lobby finished in travertine, Calacatta Crema marble, white oak, and brushed bronze; a fitness center that looks out onto the rear courtyard; and an oak-wainscotted rec room with a bar, billiards, darts, and a large-screen TV. In the units, white oak and marble finishes create a light-hued theme that carries through the living rooms (herringbone-pattern wood floors), kitchens (counters, backsplashes, and cabinetry), and bathrooms (vanities, wainscot walls, and mirror cabinet trim). The building stands on stately West End Avenue, just a block away from the Hudson River-adjacent Riverside Park and a few blocks west of Central Park; the 86th Street station (1/2 trains) sits a block away.

The development is built around a lush, landscaped courtyard with a large central fountain surrounded by wide walkways, as can be seen on the Emmy Award-winning television show Only Murders in the Building.

In its heyday, the Upper East Side's Surrey Hotel counted the likes of President John F. Kennedy, Bette Davis, and Claudette Colbert among its clientele. The hotel closed during the pandemic, but British developers Reuben Brothers bought the Schwartz & Gross-designed building in late 2020 and announced plans to reopen it as Corinthia Group's first property in the United States. Their plan also included a residential component.
Today, nearly 100 years after the hotel was completed, The Surrey, a Corinthia Hotel is open for reservations, and 13 of the 14 residences entered contracts after about six months on the market. The apartments are located on the floors above the hotel rooms to make the most of Central Park views, and the owners enjoy access to the hotel's services and amenities. These include restaurant Casa Tua and its private members club upstairs, a fitness center with patio access, and The Surrey Spa with Sisley treatments, sauna and steam room, salt relaxation room, and sensorial shower.

One Wall Street via DBOX for Macklowe Properties
One Wall Street is one of the finest pre-war condo conversion developments in all of New York City. Architect Ralph Thomas Walker, dubbed “Architect of the Century” by the American Institute of Architects, wrought the tower in an understated yet opulent Art Deco style, with walls of undulating limestone, a cavernous Red Room ground-level banking hall clad in red-orange-gold mosaic, and a matching White Room clad in mother-of-pearl seashells in the beacon-like pinnacle.
In 2020, Macklowe Properties converted the designated city landmark, together with its 28-story annex built in 1963, into 566 luxury condominiums of varying sizes, many featuring unique layouts, lofty terraces, and spectacular views of the skyline and the harbor; the iconic Trinity Church and its grounds, located across Broadway to the west, mean that every west-facing unit, even those on the lower floors, boasts open views and ample sunlight throughout the year. The 176,000-square-foot amenity suite features a two-level space on the 38th and 39th floors with a 75-foot indoor pool with panoramic floor-to-ceiling windows on three sides, a fitness center that overlooks Wall Street and the World Trade Center, several lounges, and a two-level landscaped terrace.
The White Room is now the centerpiece of a one-of-a-kind penthouse, and the Red Room is now home to the shoe salon in Printemps, an outpost of the iconic Parisian department store. Additional retail offerings in the building include a Life Time Fitness gym (with perks for residents) and the Financial District's first Whole Foods supermarket.
In 2020, Macklowe Properties converted the designated city landmark, together with its 28-story annex built in 1963, into 566 luxury condominiums of varying sizes, many featuring unique layouts, lofty terraces, and spectacular views of the skyline and the harbor; the iconic Trinity Church and its grounds, located across Broadway to the west, mean that every west-facing unit, even those on the lower floors, boasts open views and ample sunlight throughout the year. The 176,000-square-foot amenity suite features a two-level space on the 38th and 39th floors with a 75-foot indoor pool with panoramic floor-to-ceiling windows on three sides, a fitness center that overlooks Wall Street and the World Trade Center, several lounges, and a two-level landscaped terrace.

Waldorf Astoria Residences New York is the conversion of the top floors of one of New York’s most legendary hotels into condominiums. Beijing-based Dajia Insurance Group Co. was at the helm of renovating the 1931 landmark with interiors designed by Jean-Louis Deniot and an art collection curated by collector and auctioneer Simon de Pury.
The entrance to every unit features a Concierge Closet that allows for private delivery of packages, dry cleaning, and room service 24 hours a day. Interiors feature bespoke details, custom kitchens by Molteni & C, Waldorf Astoria-inspired motifs in the primary baths, multi-zone HVAC, and in-unit washer/dryers. Amenities include a private porte-cochere, an 82-foot lap pool, a fitness center with men's and women's wellness lounges, a Grand Salon, and Starlight Lounge and Terrace.
The hotel was also restored and upgraded, with iconic landmarked interiors, such as the West Lounge, Grand Ballroom, and the Park Avenue lobby, restored by the esteemed architecture firm Skidmore, Owings, & Merrill. The rooms were enlarged and enhanced, and the hotel recently reopened to guests. The meeting spaces will reopen later this year, and a Guerlain Wellness Spa is also set to debut.

Aman New York Residences via AMAN
The copper-clad pyramid roof atop the Crown Building has graced the corner of Fifth Avenue and 57th Street since 1921. Almost a century later, the ornate edifice has been reborn as Aman New York Residences, a bespoke addition to Billionaires’ Row. Owners of the twenty upper-floor condos may indulge in the services of the in-house hotel, which include a pool-equipped spa, a subterranean jazz club, a piano bar, a cigar bar, and a wine library.
In July 2024, the Crown Penthouse at the top of the building sold for just over $135 million in one of New York City's most expensive real estate sales of all time. This was instrumental in its ranking near the top of New York's best-selling buildings of 2024.

Architect Cass Gilbert traveled across Europe’s medieval cities to draw inspiration for the Woolworth Building, a 1913 Neo-Gothic masterpiece. Though the 792-foot skyscraper no longer ranks as the world’s tallest, the beloved landmark continues to evoke awe and admiration. In 2018, the slender upper portion was converted into 33 elite condominiums.
Arched windows look out through colorful terra-cotta niches onto the Downtown skyline. The wide setbacks have become twin courtyards-in-the-sky, surrounded by parapets of cusped tracery and copper finials. At the top, the former observatory and the copper-clad pinnacle house a stunning, multi-level penthouse. Of the amenities - a wine cellar and tasting room, 29th floor lounge, and 30th floor fitness center - the most impressive is the restored 50-foot basement pool, which was originally commissioned by F.W. Woolworth himself.
