Ann DesRuisseaux House: Inside Her $157M Palm Beach Mansion

Ann DesRuisseaux House, known as Casa del Ensueños, is one of Palm Beach’s most remarkable waterfront estates. Built in 1923 on 1.5 acres, the mansion offers approximately 21,500 square feet of interior space with 15 bedrooms, 18 bathrooms, and five powder rooms. Purchased by businesswoman Ann DesRuisseaux in 2020, the historic property has been meticulously restored, blending timeless architecture with modern luxury and coastal elegance.

In a market where trophy real estate keeps climbing — from tech fortunes to media empires — this estate holds its own against the country’s most talked-about private residences, the kind of homes that show up whenever people search for the Jeff Bezos House.

Ann DesRuisseaux House Tour

As Stefano Schiavon from RivonHome, I had the opportunity to visit this remarkable Palm Beach estate with a broker friend who specializes in the island’s historic luxury homes. Walking through the ornate iron gates and along the palm-lined driveway, the mansion slowly revealed its timeless beauty.

The breathtaking courtyard arch framing the Intracoastal Waterway was unforgettable, blending classic 1920s architecture with stunning waterfront views. Standing there, I understood why this legendary estate is often called a true house of dreams.

Inside Ann DesRuisseaux House: Interior and Other Features

Every room of Ann DesRuisseaux House tells part of the restoration story. Here’s a room-by-room look at the entrance, bedrooms, bathrooms, living spaces, kitchen, and standout features.

Grand Entrance

The entrance gallery sets the tone before you reach the main living spaces. Photos from the listing show cast-stone detailing around the windows and a half-round stair tower, a signature Mizner touch. The materials lean heavy and old-world: stone, iron, dark wood beams. Nothing about the entry feels rebuilt from scratch, even though most of the structure was recently redone. It still reads as 1923.

Bedrooms

Ann DesRuisseaux House has 15 bedrooms total. Listing materials describe the primary suite as having dual bathrooms and separate dressing areas, a setup built for two people who don’t want to share a sink at 6 a.m. 😄 Guest bedrooms are spread across the main house, plus a separate boathouse that was converted into its own guest quarters.

Bathrooms

Listings put the count at 18 full bathrooms and five half-baths, or powder rooms. Photos show marble-clad, spa-style finishes in at least one bath retreat, plus separate powder rooms scattered near entertaining areas. That’s a lot of marble to keep polished.

Living Spaces

Between the main residence of Ann DesRuisseaux House, guesthouse, boathouse, and tennis pavilion, the property totals about 27,000 square feet of combined indoor and outdoor living space. That includes a formal living room, a formal dining room, and a more casual kitchen-adjacent gathering space for everyday use. A performing arts theater with its own stage anchors one wing for entertaining.

Kitchen

The chef’s kitchen sits at the center of the main living areas, described in listing photos as sleek and open, flowing straight into a casual gathering space. That layout keeps whoever’s cooking part of the conversation instead of stuck behind a wall. Eight fireplaces are spread through the home, though not in the kitchen itself.

Special or Unique Spaces

Beyond the theater, the estate includes a six-car garage, a boathouse-turned-guesthouse, and a tennis pavilion beside a sunken red-clay court. Docks come fitted with a 40,000-pound boat lift. An elevator and full-house generator round out the practical extras most 100-year-old mansions don’t have. Private courts and dedicated wellness wings have become a signature feature of estates owned by wellness-and-finance figures too — think of the grounds associated withthe art-focused James Goldstein House in Los Angeles.

Security & Privacy

Ann DesRuisseaux House is gated, with landscaping and a long drive creating distance from South County Road. Listing materials mention a comprehensive security system installed during the renovation, alongside the new seawall built to handle rising tides. Privacy here comes as much from the water frontage as from any fence. 🔒

How Much Is Ann DesRuisseaux House Worth Now?

DesRuisseaux bought the estate for a recorded $24 million in 2020. It first listed in December 2025 for $175 million. By April 2026, the price dropped to $157 million, still ranking it among the most expensive homes for sale anywhere in the world — a price point that puts it in the same conversation as long-held legacy properties like the Warren Buffett House in Omaha, even though Buffett’s home is famous for its modesty rather than its scale.

Where Does Ann DesRuisseaux Live Now?

With the mansion listed for sale, her current residence isn’t publicly confirmed, and no news outlet has reported where she moved. What’s documented is her ongoing business presence in Palm Beach through her wine bar, Le Bar a Vin, which keeps her tied to the same small island community.

Ann DesRuisseaux Net Worth: How Much Money Does She Have?

No verified net worth figure exists in public reporting. What’s confirmed is the scale of this one transaction: a $24 million purchase in 2020, followed by a renovation described as costing millions, now listed at $157 million. That math alone points to serious capital, even without a headline net-worth number attached to her name.

Conclusion

Ann DesRuisseaux House Casa del Ensueños earns its reputation. A 1923 Mizner design, 15 bedrooms, a private theater, and a $157 million price tag make it one of the most significant listings in Palm Beach right now. Walking the grounds, the yacht archway is what stays with you longest.
