This $12 Million Long Island Estate Was the Summer Home of the Late Gallerist Barbara Gladstone
The late Barbara Gladstone’s name is back in the headlines this summer—not for her eponymous art galleries, but for her real estate. Just weeks after her elegant Chelsea townhouse came to market, the influential art dealer’s sprawling North Fork getaway has quietly followed suit, asking $12 million with Bridget Elkin of Compass.
Gladstone, who helped define contemporary art through her visionary gallery in Manhattan—there are outposts in Brussels and Seoul—and represented artists like Robert Rauschenberg and Keith Haring, kept the waterfront estate in Cutchogue as a refuge from the city’s art-world hustle. She died in June 2024 at the age of 89.
Spacious yet cozy living spaces feature soaring ceilings, picture windows, and multiple fireplaces.

Set on 140 feet of pristine frontage with a sandy beach on the Great Peconic Bay, the 10,000-square-foot shingle-style residence is one of the few remaining turn-of-the-19th-century summer “cottages” on the East End of Long Island to remain relatively unadulterated. This restored and updated gem beautifully blends old-world craftsmanship and modern luxury, preserving original doorknobs and hardware while seamlessly incorporating contemporary comforts. The 1.2-acre property was briefly on the market last year but has now returned with refreshed interiors and a renewed sense of quiet grandeur.

The main floor is equally suited to quiet repose and lively entertaining, with waterside living and dining rooms that both have a fireplace and fluted trimwork around the windows and doors. The chef’s kitchen is expansive, complete with a window-lined breakfast area, a butler’s pantry, and a flower-cutting room outfitted with a custom marble sink. An enormous screened porch nearby includes a summer kitchen and dining area that overlooks the bay.
The primary suite on the second floor is a cozy sanctuary with a fireplace, dressing room, extensive walk-in closets, and sweeping water views. The second and third floors contain five more bedrooms, along with a library, an office, multiple wet bars, and bathrooms outfitted with steam showers and soaking tubs.

Unfussy but beautifully maintained perennial gardens and hedged lawns frame a gunite swimming pool overlooking the water, while a charming carriage house provides additional space with a home theater, gym, and guest quarters. The estate also features a historic icehouse, a quiet reminder of its rich history.
Records indicate Gladstone owned another nearby home that she referred to as “the Guesthouse.” It was sold earlier this year for $1.94 million, a hefty chunk over the $1.8 million price tag.

A Dr. Seuss Collaborator’s Former N.Y.C. Townhouse Can Be Yours for $13.5 Million
Ever wish walls could talk? If the ones within this Upper East Side townhouse long owned by the late Phyllis Cerf Wagner could indeed speak, they most assuredly would have their share of fascinating tales to spin. Think stories of all the famous guests from Judy Garland to Frank Sinatra who visited the historic premises at some point during a 60-plus-year tenure that saw the Manhattan socialite, onetime movie actress, and collaborator with Dr. Seuss on a series of landmark children’s books outlive not just one but two prominent spouses.
Records show Wagner purchased the Italianate-style property in 1941 with her first husband Bennett Cerf, co-founder of the Random House publishing company. After he died in 1971, she went on to wed former New York City mayor Robert Wagner Jr., who passed away in in 1991, and then remained in the home until her death in 2006 at age 90. The residence subsequently sold for $8.5 million to jewelry designer Suzanne Sheik, the mother of Barely Breathing singer Duncan Sheik, before going to the current unnamed owner in 2010 for $14 million.
Now the towering 16-room spread between Lexington and Park avenues in the Lenox Hill neighborhood is being offered for $13.5 million, with the listing shared by James Weiss, Andrew Schwartz, and Ty Mabry of The Corcoran Group.

One of Ballet’s Greatest Dancers Is Selling His N.Y.C. Townhouse for $2.8 Million
Tucked away on a quiet street in Hamilton Heights, this early 1900s townhouse has long been home to a legendary pairing that effortlessly blends athleticism with artistry. Edward Villella, the trailblazing American ballet dancer who reshaped the role of men in ballet, shares the space with his wife, Linda Carbonetto Villella, a former Canadian figure skating champion. Now listed for $2.75 million with the Blumstein Team at Corcoran, this historic home is as compelling as the lives it sheltered.
Villella’s impressive dance career includes roles as a principal dancer with the New York City Ballet, a muse to George Balanchine, and the star of iconic works like Prodigal Son and Rubies. He performed at JFK’s inauguration, earned the National Medal of Arts and Kennedy Center Honors, and later founded the Miami City Ballet, turning it into a powerhouse company. Meanwhile, Carbonetto made her mark on ice, winning the Canadian national figure skating championship in 1969 and competing in the 1968 Winter Olympics before transitioning to professional skating and later nurturing ballet talent at the Miami City Ballet School.

The townhouse, originally designed as a two-family home but now a singular residence, spans roughly 3,800 square feet across five floors.

The kitchen is bright and inviting, with a balcony that opens to the backyard and plenty of space for casual meals or entertaining. A finished basement adds even more versatility, featuring a wet bar, wine cellar, and direct access to the deep private garden—a rare gem in the city. Modern conveniences like central air conditioning, gas heating, and laundry hookups on multiple floors keep day-to-day life comfortable and effortless.

Fashion Designer Lela Rose Puts Her Whimsical N.Y.C. Triplex on the Market for $10.8 Million
A newly listed triplex maisonette in the heart of Tribeca was made for fashionistas—quite literally.
The $10.8 million condo is being brought to market by the fashion designer Lela Rose. Stocked in high-end stores like Saks Fifth Avenue and Neiman Marcus, Rose has dressed numerous celebs, from Anne Hathaway to Gwyneth Paltrow. Her five-bedroom, 5.5-bath abode is clearly suited for a creative, with showstopping amenities that you’re unlikely to find in many New York City apartments. Richard Orenstein at Brown Harris Stevens holds the listing.
Tables rise from the floor and drop from the ceiling of the bamboo platform.
Brown Harris Stevens
A private street entrance leads you into the 6,000-square-foot residence, where you land in the formal living room, with 16-foot ceilings and grand gallery walls for showing off your art. Adjacent is a bamboo platform with a wet bar, where Rose carries out her “dinner theater”: Mechanized glass dining tables drop from the ceiling and rise from the floor, with space for up to 68 guests. For meals during which you’re not trying to make such a statement, a more standard dining area sits just off the stainless-steel chef’s kitchen.
Past a small lounge area, a sculptural staircase takes you up and down to the sleeping quarters. The primary suite is situated on the middle level, where the bedroom spills out to a private decked terrace. An office sits on the opposite side of the deck, and there’s a massive closet lined with red carpet. Rose is a fashion designer to the stars, after all.
A tequila tasting room is found on the lower level of the unit.
Brown Harris Stevens
Two additional bedrooms are found on the upper level, and a guest suite occupies the lower level. Down here, there’s also a playroom for kids and a temperature-controlled tequila tasting room for adults. If you’re moving in with any furry friends, there’s a whimsical dog elevator to boot—Rose’s dog couldn’t do all the stairs.
As someone who makes a living off of her taste, Rose has certainly imbued her signature style into her home. That’s a common theme when designers and their associates bring their residences to market, and we get a peek at their personal preferences when it comes to everyday living. Last month, for example, Valentino cofounder Giancarlo Giammetti listed his $17.5 million Manhattan penthouse. With a bedroom blanketed in leopard-print carpet, the unit felt quite befitting of the Italian businessman.

Tom Clancy’s Widow Just Dropped $21.5 Million on a 3-Story Penthouse in Lower Manhattan
The case is solved! Turns out the mystery buyer who recently doled out $21.5 million for a snazzy triplex penthouse at 108 Leonard in Manhattan’s Tribeca neighborhood is Alexandra Clancy, the widow of the late bestselling author Tom Clancy, who penned numerous spy thrillers ranging from The Hunt for Red October to Patriot Games. Elena Sarkissian of Douglas Elliman held the listing, with Dora Abril of Douglas Elliman repping the buyer.
Records show the seller was the building’s developer, Elad Group, which restored and transformed the former New York Life Insurance Company building known as the Clock Tower into luxury condos in 2018 in collaboration with the hospitality design firm Jeffrey Beers International. First listed in spring 2022 at around $24.5 million, the property was scooped up by Clancy in early June at a substantial discount.
A ballroom-sized great room notched into the building’s northeast corner holds living and dining areas.
Evan Joseph/Evan Joseph Studios
Originally designed by the architect Griffith Thomas and completed in 1870, the building was expanded two decades later by the legendary firm McKim, Mead & White. The ornately embellished block-long structure, which has housed notable past and present residents the likes of music industry titan Clive Davis and A-list couple Nicole Kidman and Keith Urban, was listed on the National Register of Historic Places and designated as a New York City landmark in the 1980s.
Spread across the top three floors of the 16-story Italian Renaissance Revival structure, Clancy’s light-filled aerie, dubbed the Crown Penthouse, comes with five bedrooms and seven baths. Roughly 6,200 square feet of modern living space accessible via an internal staircase and elevator boasts chevron-patterned oak floors, 15-foot ceilings, and large arched windows throughout. A trio of outdoor terraces spanning a combined 2,200 square feet also provides sweeping views of the Empire State and Municipal buildings, City Hall, the East River, and the Brooklyn, Manhattan, and George Washington bridges.
The spacious glass-lined media and recreation room is equipped with a wet bar and its own terrace.
Evan Joseph/Evan Joseph Studios
In addition to a 1,000-square-foot great room anchored by a striking marble fireplace, other highlights include an eat-in kitchen sporting custom Scavolini cabinetry, a marble waterfall-edge island, top-notch Miele appliances, and a 100-bottle wine fridge. There’s also a wet bar-equipped media/recreation room, plus a fireside primary suite that occupies the entire top floor and has a mini-kitchenette, separate sitting room, and dual walk-in closets and baths.
As for the monthly maintenance fee, Clancy will pay a hefty $10,427 per month for the privilege of living in the building, where its many premium benefits include a valet-serviced drive-in motor reception court and a 20,000-square-foot wellness area featuring a 75-foot lap pool and fitness center. Also available are a wine cellar with a private dining room and cabana lounges sprinkled amid rooftop gardens.
The primary bedroom opens to a wraparound terrace with views of 108 Leonard’s copper-clad cupola.
Evan Joseph/Evan Joseph Studios
The daughter of J. Bruce Llewellyn, a Harlem-born entrepreneur who was worth about $170 million upon his death in 2010, Alexandra Clancy worked as a TV news reporter before marrying Tom Clancy in 1999. After Tom Clancy’s death in 2013 at age 66, she was embroiled in lawsuits over the author’s $83 million estate, both with his first wife Wanda and her four children, as well as his second wife Alexandra Marie Llewellyn Clancy.
Included among Tom Clancy’s assets were shares of the Baltimore Orioles and recurring royalties and rights related to his most famous character, Jack Ryan. There was also a 400-acre Chesapeake Bay estate that Alexandra Clancy received and then sold in 2020 for nearly $5 million, much less than its $6.2 million asking price.

Art Dealer Barbara Gladstone’s Elegant Manhattan Row House Lists for $12 Million
Less than a year after Barbara Gladstone passed away at age 89, the influential art dealer’s longtime New York City home has popped up for sale, asking a brushstroke under $12 million. As first reported by The New York Times, she acquired the historic brick Greek-Revival row house in Manhattan’s Chelsea neighborhood in 2011 for $6.3 million and then spent the next couple of years revamping the place. Scott Hustis and Mark Jovanovic of Paradigm Advisory at Compass share the listing.
A visionary gallerist whose roster of contemporary artists through the years included Robert Rauschenberg, Keith Haring, Elizabeth Murray, and Jenny Holzer, the native New Yorker started her business in 1980 in a space on 57th Street that was “the size of a shoebox” and had a monthly rent of $700. Today, her eponymous dealership continues to operate out of three locations in New York, as well as branches in Los Angeles, Brussels, and Seoul.
The open-plan parlor level includes two sitting rooms on either end of a formal dining area.

Originally built in 1841 and extensively renovated during her tenure in collaboration with her friend and architect, Annabelle Selldorf, the four-level structure clocks in at 21 feet wide. Five bedrooms and an equal number of baths are sprawled across nearly 4,400 square feet of modern and refined living space boasting white oak floors and Venetian plaster walls throughout, with all floors accessible via an elevator and a sculptural sky-lit staircase sporting blackened metal railings.
Touted in marketing materials as the “perfect city home,” the garden level is highlighted by a mudroom with a secondary outside entrance, an en suite bedroom, and a powder room. At the back, the sizable eat-in kitchen features Carrara marble countertops, a professional-grade Viking range, double Miele ovens, and separate Sub-Zero refrigerator and freezer units. There’s also a butler’s pantry and a laundry room, while French doors spill out to a Piet Oudolf-designed garden.
A particularly eye-catching central curving staircase travels to all levels of the four-story residence.

Holding court on the second floor is the main entry vestibule, which opens into an open-plan great room that stretches the full depth of the house. At the front, overlooking the street, is a sitting area. A formal dining area beyond connects to another sitting room brandishing a wood-burning fireplace and a balcony with access to the garden below.
Occupying the entire third level is a primary suite boasting a second wood-burning fireplace, a balcony, a dressing room, and a stone-clad bath equipped with radiant-heated floors, a soaking tub, and a steam shower, plus an office and a wet bar. The top floor has another en suite bedroom and a gym, while the basement is currently used for storage.
Per the Times, the house was a showcase for Gladstone’s extensive personal collection of works by artists from Andy Warhol to Rudolf Stingel. A dozen pieces from her portfolio recently auctioned by Sotheby’s brought in a total of $18.5 million, with more art and furnishings expected to be sold privately or at a later auction. At the time of her death, she also owned a home on the east end of Long Island that is also on the market.Click here for more photos of the Chelsea residence.

Valentino Cofounder Giancarlo Giammetti Just Listed His Manhattan Penthouse for $17.5 Million
Giancarlo Giammetti, co-founder of the venerable fashion house Valentino, is parting ways with his stylishly appointed penthouse just blocks from New York’s Central Park.
Situated on the 54th floor of One Beacon Court, where Beyoncé once owned a place, the three-bedroom, three-bath spread was a collaboration between Giammetti and the renowned French interior designer Jacques Grange. The two worked together to compose an art-filled home that complemented the panoramic views visible through the aerie’s 40 floor-to-ceiling windows. While he’s lived in the penthouse for more than a decade, Giammetti is now listing it for $17.5 million with Allison Bandier Koffman and Juliette Janssens of Sotheby’s International Realty—East Side Manhattan Brokerage and Martha Kramer of Brown Harris Stevens.
“It’s incredible how much I discover every time I approach the windows,” Giammetti told Architectural Digest back in 2013. “Unless it’s bad weather—then I’m in a gray cloud.” Due to the vast amounts of glass, Giammetti has used the home’s limited wall space to display works by artists such as Pablo Picasso, David Hockney, and Jean-Michel Basquiat.
Leopard-print flooring adorns the primary bedroom.
Yoo Jean Han
The front-corner unit, which has three different entrances for guests and staff, opens into a rectangular entry gallery. The corner living room opens up to the library and the dining room, with the full sweep of space measuring in at 77 feet long. Here, Grange covered the floor-to-ceiling columns that break up the windows with Indian mica, adding charcoal and brass tones to the airy expanse.

“I love rooms with a darker feeling,” Giammetti said. “New York is a city of light and views, but I wanted a compromise between that openness and my love of warmer, darker tones. I would describe the look of the apartment as chiaroscuro, with rich browns and gold accents.”
The views from the 54th floor encompass Central Park and the Upper East Side.
Yoo Jean Han
The modern kitchen has been outfitted by the German manufacturer Poggenpohl, and there’s a breakfast room for more casual meals. The primary bedroom, with leopard print covering the floors, is paired with a marble-encrusted spa bath and a custom dressing room. The two additional bedrooms are located in a separate wing, and each has its own ensuite bathroom. A powder room and a laundry room complete the abode.
The 83-year-old Giammetti met Valentino Garavani in 1960, and the two founded the Valentino label that same year. Giammetti left the company in 2007, but he’s remained close with Garavani, now in his 90s, and the two created the Valentino Garavani Foundation in 2017.
