Just in case panoramic water views from one of the East Coast’s most sought-after spots isn’t enough, this meticulously renovated traditional home at 16 Marlow Court at the mouth of Cos Cob harbor on Long Island Sound in Fairfield County, CT, comes with its own .15 acre private island. Consider it an extension of your back porch, just another part of your $6.25 million private estate on 200 feet of direct water frontage with views of the harbor and the Riverside Yacht Club.

Though we’ve all probably dreamed at some point of owning a private island–and they’re more common than you may think–the serene and very private Willow Island on Putnam Lake in Patterson, N.Y., on the market for $850,000, is less out of reach than some others. On the one hand, it’s accessible only by boat. On the other, it’s less than 60 miles north of New York City in Putnam County. There’s a private driveway and garage on the mainland and multiple docks on the property. The lake is “non-motorized,” but the island comes with a solar-powered boat.
Located in the sleepy hamlet of New Hamburg in Dutchess County, separated from the banks of the Hudson River by a mere footbridge, this unique property asking $3.995 million is called Rabbit Island. And if you’re into privacy and water views with an easy commute to anywhere, you’ll want to hop on it. This pretty package includes a 4,427-square-foot house surrounded by decks and tranquil gardens, and it’s a four-minute walk from the New Hamburg train station.
Not only is Great Island in Darien, CT, the largest private island to be offered for sale on the East Coast, but before it was listed in 2016 for $175 million, this iconic property hadn’t been offered for sale or changed hands for more than a century. Purchased in the early 1900s by baking powder tycoon William Ziegler, the estate that lies just 50 miles north of New York City has remained in the family ever since. It’s asking $120 million this time around.
Own your very own private island that feels like it’s a million miles away, or at least off the coast of Maine, but is actually off the shore of Connecticut for only $4.9 million (h/t Mansion Global). With the not-at-all charming name of Potato Island, named for a group of potato-looking boulders near the shore (you say potato, we say po-tentially change that name!), this private island is part of the Thimble Islands, an archipelago of small islands, 23 of which are inhabitable, in the Long Island Sound in and around the harbor of Stony Creek in the southeast corner of Branford, Connecticut.
On a few rare occasions 6sqft has featured amazing private islands, some storied, some small–and generally for sale. Most of us dream of living on their own private island at least occasionally, and these amazing listings give us a room-by-room tour and waterfront view. Somewhere between the tiny and the impossibly grand, Whiskey Island looks an awful lot like the average private island fantasy. You can buy the 3.10 acre dream; or, if you haven’t got $2.95 million, you can rent the dream on a weekly basis for family getaways or events.
Back in 2015, 6sqft covered this unusual property. The mansion at Tavern Island is, in fact, on a 2.7-acre private island off the coast of Connecticut. Even cooler is the island’s history: The property’s main house was built in the 1930s and was home to screenwriter Lillian Hellman when she was writing “The Little Foxes,” Mansion Global reports, and theater impresario Billy Rose owned the island in the 1960s and hosted lavish parties for the likes of Marilyn Monroe, Maureen O’Sullivan, and Barbara Streisand. In addition to these epic bragging rights, the new owner of the island will gain a six-bedroom English Colonial mansion dating to 1900, private beach, swimming pool, and a docking area and boat for access the mainland. According to property records, the current owners bought the island for $950,000 in 1981.
For the third time in a 100-year history, this island compound off the North Shore of Long Island is looking for a buyer. Anybody willing to spend $125 million can own what’s known as Dosoris Island–which includes 46 acres of land, 10 acres of underwater rights and a 28-acre pond. On top of that, the island is home to a compound built by Junius Morgan, a J.P. Morgan scion, with six homes, landscaping by Frederick Law Olmsted, and all sorts of other perks. A pool, private dock, and horse stables–it’s all included in this magnificent private island package listed by Sotheby’s.
This private island upstate in Putnam County has an incredible backstory and stunning home (it’s also located just 15 minutes by plane from Manhattan, via the houses’s rooftop helipad), and it’s up for grabs at an ask of $14.92 million. Mansion Global shared the tale of how a Frank Lloyd Wright home, designed by the architect to rival his iconic Fallingwater, ended up on the grounds of this 11-acre, heart-shaped property known as Petra Island. Not only does it employ Wright’s signature cantilevering and series of outdoor terraces, but inside, there are giant stone boulders jutting into spaces from the living room to the shower stalls.
Could this insane Connecticut property break the record for the most expensive residential property ever sold in the country? Now on the market for $175 million, Great Island spans 63 acres and holds a mansion, beach cottages, a polo field, caretaker’s house with a greenhouse, yacht basin with docks, and a cow barn to boot. Such an impressive estate is owned by the family of the 19th-century industrialist William Ziegler. He acquired it in 1902 to use as a summer destination–one that rivals any other “summer house” we’ve seen. And according to The Real Deal, if this sells for its full asking price it would beat the record for priciest house ever sold in the U.S., which belongs to the 2014 sale of a $147 million home in the Hamptons.
