‘Once-In-a-Generation’ Cape Cod Estate Could Become Most Expensive Home Ever Sold in Idyllic Massachusetts Enclave

A spectacular waterfront estate on Cape Cod has hit the market for $12.9 million, a price that could rewrite the record books in one of Massachusetts' most sought-after seaside communities.

Perched on the shores of Cape Cod Bay in the town of Sandwich, the sprawling property is being marketed as a "once-in-a-generation" estate—and if it sells anywhere near its asking price, it would easily eclipse the town's current residential sales record of approximately $3.3 million.

Set amid meticulously landscaped grounds, the estate, which is listed by Michael Harney of Sotheby's International Realty, spans roughly 16,000 square feet and was designed to make the most of its extraordinary waterfront setting.

Sweeping lawns extend to a private sandy beach, while uninterrupted views stretch across Cape Cod Bay from Plymouth all the way to Provincetown.

The six-bedroom, 10-bathroom residence was created with spacious family living and entertaining in mind, offering room for both large gatherings and quiet coastal retreats.

"A once-in-a-generation waterfront estate, 12 Foxcroft Lane represents the pinnacle of Cape Cod coastal luxury," reads the listing.

Inside, soaring ceilings and walls of glass give the main living spaces a bright, open feel, with nearly every room positioned to take advantage of the sweeping views across Cape Cod Bay.

The home's expansive great room centers around a dramatic stone fireplace and flows into multiple seating and dining areas, creating a space equally suited for entertaining or quiet evenings overlooking the water.

"Light-filled living spaces flow seamlessly to exceptional outdoor entertaining areas, while the chef's kitchen opens to an inviting family room anchored by a magnificent stone fireplace—the heart of the home, where stories are shared, celebrations unfold, and a lifetime of memories begin," adds the listing.

The chef's kitchen pairs custom cabinetry with oversized islands and high-end appliances, while large picture windows keep the coastline in view even while cooking.

Several bedroom suites open onto private terraces or balconies overlooking the bay, allowing the waterfront setting to remain the focal point long after the sun sets.

Rich wood finishes, detailed millwork, and a neutral coastal palette give the interiors a timeless feel, balancing the home's grand scale with an inviting atmosphere.

Among the home's standout features is a private movie theater, a professional-grade fitness center, and an infinity-edge pool overlooking the bay.

Expansive windows throughout the home frame panoramic water views, ensuring the dramatic coastal backdrop takes center stage from nearly every room.

While the first floor is every bit of stunning, the property comes complete with even more lavish features that surely will capture potential buyers' attention.

"The luxurious first-floor primary suite is a private retreat with breathtaking views. World-class amenities include a private theater, professional fitness center, resort-style infinity pool, poolside cabana, putting green, and a private boardwalk leading directly to the beach," reads the listing.

The property's combination of privacy, direct beachfront access, and luxury amenities makes it one of the most significant residential listings to hit Cape Cod in recent years.

Outside, a poolside cabana and private putting green further enhance the resort-like setting, while a wooden boardwalk provides direct access from the backyard to the beach.

While the region is known for its collection of waterfront homes, estates of this size with an expansive stretch of private shoreline rarely become available.

"More than a home, 12 Foxcroft Lane is a legacy estate—an irreplaceable waterfront sanctuary offering unmatched privacy, extraordinary craftsmanship, and one of the finest beachfront settings on the Eastern Seaboard," the listing concludes.

Having been built in 2008—four years after the current owners bought the parcel for just $2.3 million—the listing marks the first time that this particular residence has ever been made available for sale, although the property itself has changed hands on a few occasions in the past.

And while Sandwich might not carry the same A-list cachet as places like Hyannis Port, where the Kennedy family has famously owned a compound for decades, or Provincetown, which attracts a host of tourists each year, as the oldest town on Cape Cod, it offers its own very charming amenities.
