It’s a massive hunk of limestone and red brick sitting right across from the Metropolitan Museum of Art. If you’ve ever walked down Fifth Avenue near 82nd Street, you’ve seen it. You probably stared. Most people do. The Benjamin N. Duke House isn't just another expensive piece of Upper East Side real estate; it is a literal survivor of an era when New York wasn't just wealthy—it was "gilded."
Most of these mansions are gone. Torn down for high-rise apartments or turned into boring corporate offices with fluorescent lights and linoleum floors. But not this one. It’s still there, looking exactly like a French Renaissance dream, or maybe a nightmare, depending on how much you hate dusting.
The Duke Legacy and Why This House Exists
Benjamin Newton Duke wasn't just some guy with a bank account. He was a tobacco and electric power titan. Along with his brother James B. Duke (the guy Duke University is named after), Ben helped run the American Tobacco Company. They had money. Real money. The kind of money that buys a corner lot on 1009 Fifth Avenue just to make a point.
The house was built between 1899 and 1901. Think about that for a second. While the rest of the world was figuring out lightbulbs, the Duke family was commissioning the architectural firm Welch, Smith & Provot to build an 8.5-story Italian Renaissance palazzo.
It’s huge. Honestly, it's roughly 20,000 square feet. You could fit about ten average American suburban homes inside this thing. But it’s not just about the size. It’s the fact that it stayed in the family for over a century. That almost never happens in Manhattan. Usually, the kids sell it off the second the ink is dry on the death certificate. The Dukes? They held on until 2006.
Architectural Weirdness and Grandeur
The style is officially "Beaux-Arts," but that’s just a fancy way of saying it has everything. It has limestone, it has brick, it has those iconic wrought-iron railings. The facade is a mix of textures that shouldn't work together but somehow do. It looks heavy. Solid.
Inside, it’s a time capsule.

You’ve got a winding staircase that looks like it belongs in a movie where someone gets pushed off a balcony. There are high ceilings—twenty feet high in some places—and gold leaf everywhere. If you like marble, this is your Mecca. There’s marble on the floors, marble on the walls, and probably marble in places you didn't know could be marbled.
But here is the thing: it’s narrow. For a mansion, it’s only 27 feet wide. It makes up for it by being 100 feet deep. It’s basically a very, very fancy, very tall hallway. Living there must feel like being a very wealthy ant in a very vertical colony.
The Carlos Slim Era: A Billionaire’s Hobby?
In 2006, the Duke family finally sold it for $40 million to Tamir Sapir, a real estate mogul. Then, four years later, Carlos Slim stepped in.
At the time, Slim was the richest man in the world. He bought it for $44 million in 2010. Everyone thought he was going to move in, maybe host some world-class parties, or turn it into a private museum.
He didn't.
He basically let it sit. For years.

There’s something incredibly New York about the richest man on the planet owning a 20,000-square-foot mansion across from the Met and just... not using it. He put it back on the market in 2015 for $80 million. It didn't sell. Then he listed it again in 2023 for a staggering $80 million.
People think $80 million is a lot. It is. But for a landmarked mansion on Fifth Avenue? It’s complicated.
Why Nobody Is Buying the Benjamin N. Duke House
You’d think a billionaire would snap this up in a heartbeat. But the Benjamin N. Duke House has baggage.
- Landmark Status: You can't just "fix it up." Because it’s a designated New York City landmark, you need permission from the Landmarks Preservation Commission to breathe on the walls. Want to change the windows? Good luck. Want to modernize the HVAC? Prepare for three years of paperwork.
- The Layout: 20,000 square feet sounds great until you realize it’s spread across eight floors. Unless you love stairs or trust a vintage elevator with your life, getting from the kitchen to the bedroom is a literal workout.
- Maintenance: Keeping a limestone mansion from the 1900s from crumbling costs more per year than most people make in a lifetime. The heating bill alone would make a normal person weep.
Honestly, it’s a trophy. It’s not a home. It hasn't been a "home" in the traditional sense for a long time. It’s an asset. A very pretty, very expensive, very difficult asset.
What Most People Get Wrong About the History
There is a common misconception that this was the "main" Duke house. It wasn't. James B. Duke had his own massive mansion just a few blocks away (which is now the NYU Institute of Fine Arts). The Benjamin N. Duke House was the "smaller" sibling, which is hilarious given its scale.
Another myth? That it’s haunted.

Look, any house that old with that much dark wood and creaky floors is going to have ghost stories. But there’s no documented "Duke Ghost." The only thing haunting that house is the property tax bill and the ghost of 19th-century luxury.
Why It Still Matters in 2026
We live in a world of glass towers. Everything in New York now is a "pencil thin" skyscraper with floor-to-ceiling windows and zero soul. The Benjamin N. Duke House is the opposite. It’s tactile. It has weight.
It represents a time when the ultra-wealthy wanted to plant roots that looked like they had been there for a thousand years. It’s a piece of Gilded Age history that you can still touch. When you walk past it, you aren't just looking at a building; you're looking at the last stand of an architectural philosophy that doesn't exist anymore.
Real-World Insights for the Historically Curious
If you're actually interested in the Benjamin N. Duke House, don't just stare at it from the sidewalk. Here is how to actually appreciate it:
- Check the Met's Balcony: If you go to the Metropolitan Museum of Art and get onto one of the higher floors near the front, you can get a much better angle of the roofline and the upper masonry. You can see the detail that the Dukes paid for but no one on the street ever sees.
- Research the "Duke Family" Archives: If you want the real dirt on the family, the Duke University libraries have digitized a massive amount of their personal correspondence. It paints a much more human picture of the people who lived in those cold, marble rooms.
- Monitor the Listing: Keep an eye on high-end real estate sites like Sotheby’s or Compass. When it’s on the market, they often release high-resolution interior photos that show the current state of the 1901 plasterwork. It’s the only way you’re getting inside without an $80 million bank statement.
- Visit the Neighbors: The area around 82nd and Fifth is a graveyard of Gilded Age dreams. Walk two blocks in either direction and look for the buildings that don't look like apartment complexes. You’ll start to see the remnants of the old "Millionaire’s Row."
The Benjamin N. Duke House is a stubborn survivor. It’s outlasted the tobacco empire that built it, the family that lived in it, and it will probably outlast the billionaires currently trying to flip it. It’s a 20,000-square-foot reminder that in New York, the only thing more valuable than money is staying power.
