You buy a bizarre piece of architectural history for roughly $16 million. You spend over a decade fixing it up. Then you ask for $105 million. That is the wild reality of Casa Eleda, Palm Beach's notorious "Ham and Cheese House," which is currently commanding nine-figure attention in South Florida's absurd luxury real estate market.
People love to gawk at ultra-luxury listings, but properties like this tell a much deeper story about historic preservation, skyrocketing coastal land values, and how old money estates get valued today. Let's break down why this 1928 oceanfront landmark commands such a jaw-dropping price tag and what most market watchers miss about its actual value.
The Story Behind the Ham and Cheese Nickname
Most multi-million dollar mansions have boring names derived from Latin or family crests. Casa Eleda earned a lunch-meat moniker instead.
Built back in 1928 by Swiss-born architect Maurice Fatio for investment banker Mortimer Schiff and his wife Adele—whose name spelled backward gives the estate its official title—the house features a distinct exterior. Fatio drew inspiration from Italian buildings that used horizontal banding. Instead of standard marble, he chose a striking combination of red brick and coral Key stone, also known as coquina stone.
From a distance, those alternating red and grey-ish layers made the mansion look remarkably like a giant ham and cheese sandwich. Locals picked up on the joke, and the nickname stuck for nearly a century. It's a fun quirk, but the architectural pedigree underneath is dead serious. Fatio was one of the premier society architects of his era, and the estate boasts landmark protection granted by the town back in 1979 to keep developers from bulldozing it.
The Math Behind the 105 Million Dollar Leap
Back in 2013, turnaround specialist and former Xerox executive Marion Antonini and his wife Penny picked up the property for $15.975 million. At the time, that was serious money, but a bargain compared to what happened next.
They didn't just move in. They treated the 13,000-plus-square-foot mansion as a massive passion project. The home was dark and dated when they bought it, but it had incredible bones. They spent years meticulously restoring carved stonework, hand-painted and beamed cypress ceilings, intricate coffered details, and the original fireplaces. They even rebuilt the swimming pool to mimic one found in a Venetian church.
That restoration won a preservation award in 2017. When Marion Antonini passed away in 2021, the stage was set for the estate's next chapter.
Jumping from $15.9 million to $105 million sounds insane on paper. But look closer at Palm Beach's Estate Section. Oceanfront land on the island is basically finite. With roughly 150 feet of direct Atlantic frontage, an acre of prime dirt, and a pristine historical structure, you are paying for absolute scarcity. Right now, joining a very exclusive club of fewer than ten homes on the entire island asking over $100 million isn't about square footage anymore. It's about owning a museum-grade trophy asset that nobody else can ever replicate.
The Secret Underground Tunnel You Didn't Know About
One feature sets Casa Eleda apart from almost every other oceanfront estate on the Gold Coast. It has a private underground tunnel running directly beneath South Ocean Boulevard.
If you live on the water in Palm Beach, crossing a busy coastal highway to reach your stretch of sand is an annoying daily chore. Fatio solved this problem in the 1920s by engineering a subterranean passageway.
You walk from the main residence, slip beneath the street, and pop out inside a private oceanfront cabana equipped with its own living room, wet bar, and full bathroom. Try building that kind of infrastructure today. Between local zoning laws, environmental regulations, and modern traffic codes, getting approval for a private tunnel under a state road is practically impossible. That single engineering feature adds millions to the property's functional utility for a high-profile buyer who values privacy above all else.
What Buyers Actually Look For at This Price Level
When you list a property at nine figures, traditional comps go out the window. Buyers looking at a $105 million price tag aren't taking out mortgages. They are tech founders, global financiers, or generational wealth holders parking capital in hard assets.
They want three specific things:
- Zero construction headache: Nobody wants to spend three years wrangling contractors through historic board approvals. The Antoninis already did the heavy lifting and won awards for it.
- Absolute privacy: The tunnel, high hedges, and gated layout make it a fortress against prying eyes.
- Instant legacy status: Owning a Maurice Fatio original with a famous moniker gives a buyer immediate social standing in Palm Beach high society.
Properties like the Ham and Cheese House prove that rare architecture paired with obsessive restoration creates its own economic reality. Whether it fetches the full asking price or settles slightly lower, it remains a masterclass in how historic preservation can turn a quirky 1920s sandwich-looking mansion into a nine-year goldmine.
Take a close look at your own real estate investments or portfolio assets. True scarcity always wins in the long run.
