Directly east of Midtown's prominent office towers is one of its more peaceful enclaves. Turtle Bay spent centuries as farmland, and its residential renaissance began over 100 years ago when Charlotte Hunnewell Sorchan bought and renovated a row of townhouses, created a garden from their adjoining backyards, and dubbed the project Turtle Bay Gardens. She sold the houses at cost to friends like Maria Bowen Chapin, and later residents included E.B. White (who reportedly named the title character of Charlotte's Web in Ms. Sorchan's honor), Stephen Sondheim, Katharine Hepburn, and Olivier Sarkozy.
The area got another boost in the late 1940s when the United Nations headquarters was built on 18 acres of cleared commercial land. Diplomatic missions took shape on surrounding streets, sometimes in converted townhouses, in a move that lent the neighborhood a global flair.
In this article:
More recently, Turtle Bay has experienced an influx of modern high-rise condominiums. While the twenty townhouses of Turtle Bay Gardens are protected by the Landmarks Preservation Commission, the rest of the area is not. This fact, along with a 2017 Midtown East rezoning, has allowed tall buildings to take advantage of river views to the east and skyline views to the west.
The next one on the horizon is Beekman, a 29-story condo tower taking shape at 401 East 51st Street, on the corner of First Avenue. In June 2023, SK Development purchased the properties at 930 First Avenue, 936 First Avenue, and 401 East 51st Street for $46.8 million. From there, they filed demolition permits, teamed up with CB Developers, and announced plans for a new project. Most recently, construction has topped out at 29 stories high, and a striking facade by Selldorf Architects is on the way up. The red terra cotta panels feature a repeated, faceted pattern that captures light and shadow throughout the day. The pattern appears almost quilted, and gives the building depth and visual movement.
Beekman's 83 studio to five-bedroom apartments will start on top of retail space and a parking garage, and include duplexes and one triplex. Prices are expected to start at $1 million and exceed $10 million. Residential amenities will include a coworking lounge, a dining room with outdoor terrace, a fitness center, a golf simulator, a pet wash, private storage, bike storage, and on-site parking.
Beekman's residents will also enjoy Turtle Bay's unique balance of connectivity and tranquility. While Turtle Bay is technically defined as East 42nd Street to 53rd Street between Third Avenue and the East River, the boundaries with the nearby Beekman/Sutton Place enclave are extremely porous. In any event, simple geography puts this neighborhood far enough east to offer some respite from the chaos of the city. The East Midtown Greenway also offers a touch of serenity. Part of the Manhattan Waterfront Greenway, a 32-mile loop of public land around Manhattan, it offers lush landscaping, a new pedestrian bridge, a dog run in Andrew Haswell Green Park, and beautiful, tranquil views of the East River.
However, that is not to say that Turtle Bay is completely isolated. It is in a central location that allows for easy access to Grand Central Terminal, United Nations headquarters, Midtown offices, fine dining, and high-end shopping. The Tudor City complex and the site of Freedom Plaza, Soloviev Group's proposed waterfront casino complex, are located just south of the United Nations headquarters.
Below, we look at forthcoming projects that are further poised to reshape Turtle Bay. For those who do not want to wait that long to move to this dynamic yet peaceful neighborhood, we present a selection of the top ten condominiums that brought the neighborhood to prominence with units that are available for immediate move-ins.
New Developments in Turtle Bay - Beekman/Sutton Place
Rental | Completed in 2025
Design by BKSK Architects | 194 units
3 availabilities from $6,900/month
Up to 0.5 months free rent on a 12-month lease
Leasing is underway at Anagram Turtle Bay, a new 23-story residential rental tower located at 300 East 50th Street at the southeast corner of Second Avenue. The project is a joint development by MAG Partners, a woman-owned New York-based real estate company, and Global Holdings, an international firm led by Eyal Ofer. The building includes 194 rental units, 30 percent of which are designated as affordable through the Affordable NY program.
Designed by BKSK Architects, the tower is the latest addition to the Anagram residential collection and includes a mix of studios to three-bedroom layouts. Apartments feature oversized windows, white oak-style flooring, in-unit Bosch washers and dryers, programmable climate control, and keyless entry. Kitchens have quartz countertops, full-height porcelain tile backsplashes, and Bosch appliance packages with induction cooktops. Most units include walk-in closets and integrated blackout shades; bathrooms vary by unit and include materials such as mosaic tile, quartz vanities, terrazzo flooring, and porcelain tile. A collection of "Residences From The Top" offers elevated ceiling heights, magnificent views, and private terraces in select units.
Amenities span three floors and include a fitness center, rooftop terrace with grilling stations and sun loungers, landscaped garden lounge with an apertivo bar, library and study spaces, and a media lounge with a fireplace.
MAG Partners Founder and CEO MaryAnne Gilmartin noted the project’s alignment with the firm’s broader development goals. “Anagram Turtle Bay — which remarkably tracked on the same construction and launch timelines [as Mabel] — demonstrates our commitment to building with integrity,” Gilmartin said. “Every detail has been given the deepest level of thought and consideration as we help raise the standard of what it means to live in New York City.”

In addition to the residential component, the development will include a new restaurant from the Serafina Group. Serafina Mare, a seafood-focused offshoot of the brand, will occupy the entire ground floor and is expected to open later this year. It will offer residents perks such as room service and dining discounts.

Rental | Completion estimated for 2028
Design by ODA Architects | 44 units
A pair of unassuming walk-up buildings were once situated at 303-305 East 44th Street, but grand plans for a glassy skyscraper with lifted organically-shaped divisions designed by ODA Architects were once imagined for the site. Demolition permits were filed in 2016; but in March 2018, The Real Deal announced that the project was put on hold until further notice. A softening condo market was a factor, and a rent-controlled holdout didn't help.
A recent visit to the site shows that construction is finally proceeding after a fresh set of permits were filed in 2024, revealing a new but still slender, pared down design. ODA is still helming the design of the 470-foot-tall building which will include 131 condominium units and 8,000 square feet of ground-floor retail.

Condominium | Completion estimated for 2027
Design by Issac & Stern Architects | 29 units
After several years in development limbo, construction is officially underway on a new 19-story, 29-unit condominium at 1009 Second Avenue, between East 53rd and 54th Streets. Developed by NAL Management and designed by Issac & Stern Architects, the slender mid-block tower rises beside the Fox & Fowle-designed Mondrian condo and faces the mid-century pool-topped co-op, Connaught Tower, across Second Avenue.
Architects describe the façade as a study in contemporary elegance, with full-height window walls framed in a staggered metal pattern. Built in an R10 zoning district with a Floor Area Ratio (FAR) of 12, the project gained additional FAR through inclusionary housing incentives. The building’s total gross square footage will be approximately 51,100 square feet.
To be constructed with a reinforced concrete frame, the tower will include a ground-floor restaurant, building services and storage in the cellar, and condos on top. The building will feature no more than two residences per floor, transitioning to full-floor homes with expansive private terraces above the 14th floor. These upper units will offer partial views of the East River.
Interior renderings depict apartments with open layouts, abundant natural light, and kitchens with dining peninsulas and integrated appliances. Amenities will include a fitness center, a spa with hammam and cold sauna, and a landscaped rear courtyard.
Rental | Completion estimated for 2027

In May 2025, prolific office-to-residence developer VanBarton Group filed permits to expand the former headquarters of the Archdiocese of New York by six stories and convert the building to new housing units in a central location. Our Town notes that the developer is taking advantage of the 485x tax program; as such, a portion of the apartments will be affordable. The archdiocese has moved to new space near St. Patrick's Cathedral.
Condominium | Completion estimated for 2028
Design by Hill West Architects | 141 units
In April 2026, developer EJS Group and Krown Point Capital filed permits for a high-rise tower on the cusp of Sutton Place and Midtown East. The apartments will start on top of ground-floor retail space, and amenities will include a fitness center, a coworking lounge, and bike storage. Another perk will be a central address near Midtown East offices, Bloomingdale's, fine dining, Whole Foods and Trader Joe's, and transportation options that include multiple subway lines and the Roosevelt Island tramway.
Condominium | Converted in 2001 (new sponsor units released)
Design by Costas Kondylis | 64 units
5 availabilities from $2,450,000
In August 2024, a package of 26 sponsor condos was released at The Beekman Regent, which was converted from rentals to condos in the early 2000s. The property package includes two- to four-bedroom apartments with townhouse and penthouse units among them, and select units have private outdoor space. Like all residents in the building, these owners will enjoy access to amenities like a fitness center, sauna, lounge, library, private storage, and valet parking.
The release of the new units represents the latest chapter in The Beekman Regent's rich history. The original Romanesque building at 351 East 51st Street was constructed in the late 19th century as Primary School No. 35, which later became PS. 135. When the Board of Education decided to sell the building to a developer who might have demolished it, local preservationists succeeded in getting it on the National Register of Historic Places. The original school is now retail space, the new condominium went up above it, and the resulting design was the 2002 winner of the Mercedes Benz Property Award for "Finest New Redevelopment in the World."

The Perrie is a rental-to-condo conversion where the 95 one-bedroom units include a five-unit collection of penthouses with private roof terraces. Most units will have private balconies, and all residents will have access to an attended lobby, courtyard garden, fitness center, and lounge.
The new condominium represents the latest chapter for 234 East 46th Street. Crowdfund investor Prodigy originally intended to develop 234 East 46th Street into a long-term hotel with Korman Communities under its AKA brand. However, this didn't pan out and Prodigy filed for bankruptcy in 2021. The Perrie's developer, Cape Advisors, bought the building for $13 million in May 2023.

As of this writing, the boutique condominium at 249 East 50th Street is sold out. All the units feature oversized windows, high ceilings, hardwood floors, kitchens with custom cabinetry and stainless steel appliances, and in-unit laundry. Residential amenities include a central courtyard, an attended lobby, a fitness center, bike storage, and a roof deck.
The building is located in close proximity to fine dining, but one of Manhattan's fanciest restaurants once stood on the site: After chefs James Beard and Andre Surmain taught cooking classes in the drawing room of Mr. Surmain's townhouse, Mr. Surmain later turned it into Lutece. The restaurant appeared in numerous films, but closed in 2004 amidst a drop in tourists and tightening dining budgets after 9/11. Plans for a residential condo go back to 2006, but the Great Recession and later the pandemic stalled proceedings.

At 62 stories and 847 feet tall, Sutton Tower is the tallest building in its neighborhood and second only to supertall 432 Park Avenue as the tallest building in Midtown East. The tower has undoubtedly changed the local skyline, but the limestone pillar and coffered crown pay tribute to historic architecture.
Inside Sutton Tower, no more than three units per floor allows for excellent privacy and spacious floor plans. Amenities are spread across four light-filled floors and include a fitness center, a 50-foot indoor pool, a spa area with infrared saunas and treatment rooms, a private dining room with chef's demonstration kitchen, a game room, and a children's playroom.

United Nations Permanent Mission of Qatar expansion — 809 United Nations Plaza
Consulate | Completion TBD
Design by Tankhouse
Years after the Qatar Investment Authority bought five commercial condo spaces at 809 United Nations Plaza, home to its permanent mission to the United Nations, in November 2019, construction is underway on expanded headquarters. Renderings show a short, tasteful tower on the East River waterfront with gold accents.
809 United Nations Plaza was home to the Edgar J. Kaufmann Conference Center, which was one of five works ever completed in the United States by Finnish architect Alvar Aalto. It is distinguished by its blue tiled elevator lobby, custom-designed bronze light fixtures, and wood detailing throughout. Preservationists have lobbied to make the Kaufmann Conference Center a New York City Landmark. This has not come to pass; however, the space was donated to the country of Finland in July 2024, and they have made arrangements to dismantle, store, and eventually create traveling exhibitions out of this piece of architectural history.

Trump World Tower's reputation has taken a hit in recent years because the former president's name is still on the building (despite some residents' efforts), but the building remains the tallest in Turtle Bay. By virtue of its soaring height and glassy facade, residents enjoy sweeping views of the East River and Manhattan skyline. The cornerstone of the amenity package is a 10,000-square-foot health club with a 60-foot lap pool; additional offerings include 24-hour doorman/concierge service, maid service, valet parking, a wine cellar, and a private park.
