It is the only private island in Palm Beach. Think about that for a second. In a town where billionaires fight over inches of hedge height, someone owns the whole landmass. 10 Tarpon Isle, Palm Beach, FL 33480 isn't just an address; it is a geographic anomaly that recently underwent one of the most aggressive luxury redevelopments in American history.
Most people see the price tag—originally asking $218 million—and assume it’s just another "spec house" on steroids. It isn't. Todd Michael Glaser and his partners didn't just renovate a house here. They essentially rebuilt a private ecosystem. You’ve got water on all four sides. Total seclusion. No neighbors sharing a fence. Just 360 degrees of the Intracoastal Waterway and the constant hum of the Florida sun.
The Transformation of the Island
Back in 2021, the property looked a lot different. It was still the only private island in the 33480 zip code, but it was dated. It had a British Colonial vibe that felt a bit "old Palm Beach." Glaser, a developer known for moving fast and spending big, bought it for about $85 million. Then the real work started.
They expanded the living space to roughly 21,000 square feet. This wasn't just adding a wing; it was a total reimagining. They brought in Roger Janssen of Dailey Janssen Architects to handle the design. The goal was to create something that felt like a modern Mediterranean estate but functioned like a world-class resort. It's sprawling. It's massive.
Actually, calling it a house is kind of an understatement. It's more like a compound. You have the main residence, a massive guest house, and then the amenities that usually require a club membership. We’re talking about a private tennis court—one of the few on the water—and two pools. One is a 98-foot lap pool, and the other is a cold plunge. Because apparently, when you live on your own island, you need options for how you get wet.

What $200 Million Actually Buys You
People always ask what makes 10 Tarpon Isle, Palm Beach, FL 33480 worth that kind of money. Is it the marble? Sure, the finishes are insane. But you're paying for the dirt. Or, specifically, the lack of dirt connecting you to anyone else.
Privacy is the ultimate currency in Palm Beach. On the "Estate Section" of South Ocean Boulevard, you still have people driving by your front gate. At Tarpon Isle, you have a private bridge. It’s a gated entry to a gated island. If you want to disappear, this is how you do it.
The interior layout is built for entertaining on a scale that most of us can't really wrap our heads around.
- The Wellness Wing: It has a steam room, sauna, massage room, and a hair salon. You don’t leave the island for a haircut.
- The Entertainment Hub: A library with a bar, a movie theater, and a wine room that holds more bottles than some local liquor stores.
- The Outdoor Space: You have 1,300 feet of water frontage. That is a massive amount of dockage. You could park a fleet of yachts here and still have room for the jet skis.
One thing that often gets missed in the glossy brochures is the elevation. In South Florida, "high ground" is relative, but they did significant work to ensure this island stays dry. The landscaping is lush, designed to act as a natural screen, so even though you’re surrounded by water, you don’t feel like you’re in a fishbowl.

Real Estate Reality Check
Let's talk numbers, honestly. The property made headlines when it hit the market for $218 million. It eventually sold for $150 million in 2024. Some people called that a "price cut," but that’s a bit of a cynical take. A $150 million closing is still one of the most expensive residential sales in the history of the state. It proved that there is a ceiling, even in Palm Beach, but that ceiling is still way up in the stratosphere.
The buyer was an entity linked to a high-net-worth individual—shocker, I know—who clearly valued the "one-of-one" nature of the site. You can always build a bigger house. You can buy more gold leaf for the ceilings. What you cannot do is create another private island in the middle of the Lake Worth Lagoon. The town isn't making any more of them.
The Logistics of Living at 10 Tarpon Isle
Living here isn't just about the views. There's a logistical side to owning an island that most people don't think about. You’ve got a private bridge to maintain. You have 360 degrees of seawall that needs constant inspection. The salt air is brutal on structures, meaning the maintenance crew for a place like this is likely larger than the staff at a boutique hotel.
The home uses a massive amount of glass to take advantage of those water views. This requires specialized impact-resistant glazing that can handle a Category 5 hurricane. Everything is "over-engineered." It has to be. When you’re sitting on a man-made island in a hurricane zone, you don't skimp on the foundation.

Comparing 10 Tarpon Isle to the Rest of Palm Beach
| Feature | 10 Tarpon Isle | Typical PB Estate |
|---|---|---|
| Privacy | Absolute (Private Bridge) | High (Gated Walls) |

Palm Beach is full of "Grand Dames"—homes built by Addison Mizner or Maurice Fatio in the 1920s. Those houses have history. Tarpon Isle has something different: autonomy. It's a statement of modern engineering and contemporary luxury. It’s for the person who thinks Mar-a-Lago is a bit too crowded.
What the Critics Say
Not everyone loves the "spec-u-lative" nature of these builds. Some architectural purists think these massive modern boxes lack the soul of the old Mediterranean Revival homes that defined the town. They argue that 10 Tarpon Isle is a "party house" for the ultra-wealthy rather than a family home.
Maybe. But looking at the floor plan, it’s hard to argue with the utility. Every bedroom is a suite. Every window is a frame for the water. It’s designed for the way people live now—indoor-outdoor flow, massive kitchens that look like art galleries, and spaces dedicated entirely to "wellness."
Actionable Insights for the High-End Market
If you are tracking the Palm Beach market or looking at ultra-luxury assets, 10 Tarpon Isle, Palm Beach, FL 33480 offers a few key lessons:
- Scarcity Trumps Everything: The house is great, but the island is the asset. Always look for the "un-reproducible" element in a property.
- Wellness is the New Luxury: Notice how much square footage is dedicated to health. A gym isn't enough anymore; you need a full-service spa within your own walls.
- Dockage Matters: In Florida, water access is a huge value driver. Having enough space for multiple large vessels adds tens of millions to a property's valuation.
- The "Spec" Premium has Limits: Even the most beautiful island in the world has a price cap. The jump from an $85 million purchase to a $150 million sale is a massive win for the developers, but the $218 million ask was a "reach" price that the market eventually corrected.
For those interested in the architecture or the specific history of the island, the property remains a landmark of the Glaser era of Palm Beach development. It represents a shift toward "resort-style" living where the home is no longer just a place to sleep, but a self-contained universe.
Practical Next Steps for Following the Palm Beach Market
- Monitor the MLS: Keep an eye on the 33480 zip code for "off-market" listings that often leak through high-end boutique agencies like Lawrence Moens or Christian Angle.
- Research Coastal Construction: If you're looking at island properties, study the latest FEMA flood maps and seawall requirements, as these are the biggest "hidden" costs in Florida real estate.
- Track Speculative Trends: Watch Todd Michael Glaser’s newer projects in the area to see if the "wellness-heavy" design trend continues to evolve or if the market shifts back toward traditional styles.
