Inside a $218 million private island in Palm Beach — Florida’s most expensive home for sale

A private island in Palm Beach could become the most-expensive home ever sold in Florida, if it gets its asking price of $218 million.

Developer Todd Michael Glaser and his partners bought 10 Tarpon Isle — the only private island in Palm Beach — for $85 million in 2021. They built a brand new house, turned the existing structure into a guest house, and added a giant pool, tennis courts and other amenities and have now relisted the property.

“I paid $85 million without a hesitation because there’s only one of them,” Glaser said. “You watch art, they sell. There’s a Mercedes 300 SLR that just sold for $142 million. … That’s what this is … it’s a one of one.”

When Glaser bought Tarpon Isle, it held a modest 1940s house and plenty of potential.

“I came over the bridge, I saw the two trees and I said, ‘Guys, let’s knock down the garage and the guest house and the maid’s quarters and let’s build a brand new house,'” Glaser said.

The new main house is over 9,000 square feet. With the guest house, tennis pavilion and other structures, the property now has over 21,000 feet of living space. There are 11 bedrooms, 15 full bathrooms and seven half-baths.

Unlike many Palm Beach mansions, which are Mediterranean-styled giants festooned with gold carvings and mahogany, Tarpon Isle is a study in modern simplicity, where the star of the home is sweeping water views on all four sides.

The master bedroom suite is a large complex of closets, bathrooms and sitting areas. The larger of two bathrooms is a temple of white Italian marble, covering the floors, countertops, ceiling and oversized shower. A large soaking tub perched in front of the windows overlooks the Intracoastal Waterway.
