There’s a side of Westchester that can feel more like coastal New England than suburban New York.
Follow the shoreline from New Rochelle through Larchmont and Mamaroneck to Rye and you’ll find rocky peninsulas, hidden coves, yacht clubs, private islands and some extraordinary homes overlooking Long Island Sound.
This is Westchester’s Sound Shore, a roughly 36-mile region where waterfront living has attracted New Yorkers for generations. After the Civil War, newly wealthy families began building elaborate estates on hills overlooking both the Hudson River and Long Island Sound. By the late 19th and early 20th centuries, communities such as Larchmont had become fashionable summer retreats.
Today, the shoreline contains everything from restored Gilded Age residences and 1920s Tudors to Frank Lloyd Wright architecture and contemporary glass-filled estates.
And some are spectacular.
A Private Peninsula in Rye
It’s difficult to find a Westchester property that demonstrates the possibilities of waterfront real estate quite like this Rye estate.
The Shope Reno Wharton-designed residence encompasses approximately 10,400 square feet, but it’s the land surrounding it that makes the property extraordinary.
Set on a private peninsula, the estate has been described as having roughly 1,100 feet of waterfront, along with a protected inlet and docking for two boats.
From above, the setting is remarkable.
A huge manicured lawn meets the water. A tennis court sits near the shoreline. The residence looks toward Long Island Sound while a curved seawall and protected harbor wrap around the property.
Inside, publicly available descriptions have noted six bedrooms, a wine cellar, gym, cherry-paneled library and Honduran mahogany study.
The property reportedly sold for $12.75 million in a previous transaction.
It’s less like owning a waterfront house than owning your own little piece of the Westchester coastline.
Villa Cheri — Larchmont
Then there’s Villa Cheri, one of Larchmont’s most distinctive waterfront residences.
The home dates to 1898, placing its origins squarely within the period when Larchmont was becoming a fashionable shoreline retreat.
Today, following an extensive multiyear renovation, the residence combines its historic origins with contemporary luxury.
The numbers alone are impressive: approximately 9,231 square feet, seven bedrooms, 12 bathrooms and 1.38 acres overlooking Long Island Sound.
But this isn’t simply a large house near the water.
The architecture is oriented toward it.
Large windows, terraces and outdoor entertaining spaces frame the Sound, while the property’s lawns and landscaping create a transition between the house and shoreline.
It’s an interesting example of what happens when one of Westchester’s historic coastal homes is reimagined for modern living without losing the grandeur that made the location special in the first place.
Cedar Island — Larchmont
If the idea of living on an island sounds more Nantucket than Westchester, consider Cedar Island.
Cedar Island sits off Larchmont overlooking Larchmont Harbor and Long Island Sound.
And one of its standout residences is a waterfront Tudor dating to 1925.
The approximately 8,800-square-foot home sits on about 1.25 acres and combines stone, stucco and classic Tudor architecture with a setting that would be difficult to reproduce today.
Historic interior elements have included leaded stained-glass windows, vaulted beamed ceilings, extensive millwork and multiple fireplaces.
Outside is where things become extraordinary.
A broad lawn runs toward the water. There’s a swimming pool tucked into the landscape and a long private dock extending directly into the harbor.
From the air, the property looks less like suburban Westchester and more like an old coastal estate somewhere along the New England shoreline.
Why Larchmont Has So Many Extraordinary Waterfront Homes
Larchmont’s coastal architecture isn’t an accident.
The village was originally established as a summer shoreline retreat for wealthy New Yorkers, and that history remains visible in the Larchmont Manor neighborhood, where grand Victorian-era vacation homes still survive.
Perhaps the best place to understand why people wanted to build here is Larchmont Manor Park.
The approximately 12½-acre park follows about 5,000 feet of Long Island Sound shoreline, with lawns, rocky outcroppings and sweeping water views. Remarkably, property owners have shared the waterfront with neighbors and visitors since 1872.
Stand there at sunrise and Larchmont’s development as a summer colony suddenly makes perfect sense.
The Grand Estates of Premium Point — New Rochelle
Travel south and the waterfront becomes even more dramatic.
New Rochelle has miles of shoreline broken into islands, coves and peninsulas, creating opportunities for houses to sit almost surrounded by water.
One of its most exclusive historic enclaves is Premium Point.
The gated peninsula has long been associated with substantial waterfront estates, and some of the homes here look remarkably removed from a city that’s only a short train ride from Manhattan.
One residence pictured above demonstrates why.
A grand white mansion with a red-tile roof sits between manicured lawns and open water, its terraces looking directly toward Long Island Sound.
Another nearby property occupies an extraordinary rocky promontory, with lawns extending toward the edge of the Sound and views back toward the New Rochelle skyline.
It’s a fascinating juxtaposition: private coastal-estate living with a city visible across the water.
All View — One of New Rochelle’s Great Historic Estates
Premium Point is also home to a particularly fascinating piece of Westchester architectural history: All View.
The historic residence sits on approximately 2.8 acres at the end of the peninsula, overlooking Echo Bay, Premium Mill Pond and Long Island Sound.
And this is not a modest summer cottage.
The estate contains approximately 21,000 square feet and 28 rooms, with eight bedrooms and extensive waterfront grounds.
The architecture has sometimes been incorrectly attributed in real-estate material to Stanford White; historical accounts identify architect Sidney Vanuxem Stratton as the designer. The grounds have been associated with legendary landscape architect Frederick Law Olmsted, designer of New York’s Central Park.
Its position on the bluff is what makes All View particularly dramatic.
Water surrounds the property on multiple sides, giving the estate exactly what its name promises.
Views.
Everywhere.
A Modern Coastal Retreat in Larchmont
Not every extraordinary Sound Shore home is historic.
This Larchmont waterfront residence shows how differently modern homeowners are approaching the same coastline.
Instead of heavy stone walls and formal Tudor interiors, the emphasis is on light.
White exterior surfaces, large expanses of glass and open terraces create an almost resort-like relationship between the house, lawn, swimming pool and water.
The architecture becomes quieter so the Sound can become the focal point.
It’s a style increasingly associated with high-end coastal homes: fewer barriers between indoors and outdoors and major living spaces positioned specifically around the view.
Watersmeet — Rye
Rye also contains waterfront properties where the landscape feels much older and more established.
Watersmeet is one of them.
Built in 1925, the approximately 10,000-square-foot Colonial-style residence sits on more than two acres of waterfront property.
From above, much of the house nearly disappears beneath mature trees.
Then the shoreline appears.
Stone terraces descend toward the water, while a swimming pool is positioned close enough to the shore that the entire backyard feels integrated into the landscape.
It represents a different kind of luxury than a newly constructed glass mansion.
The appeal is maturity.
Trees that have been growing for generations.
Old stone.
Established gardens.
And a house that looks as though it belongs exactly where it is.
The Frank Lloyd Wright House Hidden on Manursing Island
And then there’s a house that belongs in an architectural category of its own.
Max Hoffman House was designed by Frank Lloyd Wright for European automobile importer Max Hoffman and completed in 1955.
The waterfront residence sits on North Manursing Island in Rye, where Wright’s architecture was designed around its relationship with the landscape and Long Island Sound.
It later attracted another famous owner: fashion designer Marc Jacobs, who purchased the house in 2019 and undertook an extensive restoration.
Unlike some of the enormous waterfront mansions nearby, the appeal here isn’t simply square footage.
It’s pedigree.
Owning a Frank Lloyd Wright house on Long Island Sound is something entirely different.
And because it remains a private residence within a gated community, it’s also one of Westchester’s more intriguing hidden architectural treasures.
North Manursing Island — Rye
Some of Rye’s most impressive waterfront homes sit within North Manursing Island, a private enclave where houses can enjoy open Sound frontage as well as views toward protected harbors.
One documented property illustrates the scale of these homes particularly well.
Built in 2004, the approximately 8,200-square-foot stone-and-slate residence was positioned to capture both roughly 240 feet of direct Long Island Sound frontage and views across Tide Mill Harbor. It includes five bedrooms, seven full baths and a four-plus-car garage.
The surrounding community contains just a few dozen estates, with private roads, access to a community marina and a private association beach.
That’s part of the appeal of Manursing.
You’re technically in Rye.
Downtown and Metro-North aren’t far away.
Yet from the backyard, your world can consist almost entirely of water, boats and sky.
Mamaroneck’s Orienta and Shore Acres
Between Larchmont and Rye lies another important piece of Westchester’s waterfront history.
The Village of Mamaroneck identifies Shore Acres, Greenhaven and Orienta as Sound-side neighborhoods that were once owned by wealthy New York City families as summer residences.
The legacy remains visible today.
Orienta in particular contains winding residential streets, waterfront clubs and estates tucked around Mamaroneck Harbor and Long Island Sound.
Edgewater Point extends into the water from Orienta, creating another of those unusual Westchester settings where residences can have broad harbor and Sound views.
These aren’t neighborhoods built around water as an amenity added later.
The water is the reason the neighborhoods exist.
The Colonial Estate Overlooking the Sound in Rye
Then there are homes that look almost exactly like what you might imagine when someone says “Westchester estate.”
This grand brick Colonial in Rye combines a symmetrical façade, tall white columns and formal circular drive with something considerably harder to reproduce:
Long Island Sound immediately behind it.
From the front, it looks like a classic Westchester country estate.
From the back, the landscape opens into a broad lawn followed by uninterrupted blue water.
That contrast—traditional East Coast architecture in front and coastal living behind—is one of the defining characteristics of Rye’s most impressive waterfront properties.
Why These Homes Are So Rare
Luxury homes can be built almost anywhere.
True waterfront cannot.
Westchester’s Long Island Sound shoreline is finite, and much of it was developed generations ago. Modern buyers therefore aren’t simply competing for houses.
They’re competing for position.
A protected cove.
Deep-water dock access.
A private beach.
A rocky promontory.
A peninsula.
An unobstructed sunrise.
A lawn that actually reaches the Sound.
And those qualities can’t simply be recreated by building a bigger house.
That’s why waterfront properties in Rye, Larchmont, Mamaroneck and New Rochelle occupy such a distinctive niche within Westchester’s luxury market.
Westchester’s Other Gold Coast
When people around New York hear the words “Gold Coast,” they generally think of the famous estates across Long Island.
But Westchester has its own remarkable coastal corridor.
It stretches from the rocky shoreline and historic mansions of New Rochelle through the old summer estates of Larchmont and Mamaroneck and into the private peninsulas and islands of Rye.
Some homes date to the Gilded Age.
Some were built during the great suburban expansion of the 1920s.
One was designed by Frank Lloyd Wright.
Others are thoroughly contemporary.
Yet all of them share the feature that ultimately matters most.
Walk through the house, open the doors and continue across the lawn.
Eventually, Westchester ends—and Long Island Sound begins.
