Carlos Slim House: Inside the Billionaire’s Fifth Avenue Mansion and His Quiet Mexico City Home
Carlos Slim Helú’s real estate portfolio is surprisingly different from what you might expect from one of the world’s richest men. Featured on Urbansfreaks, his property story centers on two very different homes:
a landmarked Fifth Avenue mansion in Manhattan, once listed for $80 million, and a more modest six-bedroom residence in Mexico City, where he has reportedly lived for decades. Just Like Jeff Bezos House .Together, they show a quieter side of billionaire real estate.

Carlos Slim House New York Location
The mansion sits at 1009 Fifth Avenue, on the corner of East 82nd Street. It faces Central Park directly. The Metropolitan Museum of Art stands right across the street.Just Like James Goldstein House.
This stretch of Fifth Avenue is often called Millionaire’s Row. Very few private homes remain here today. Most of the block has turned into co-ops and museums, which makes this address rare.
My Visit to Carlos Slim House
As Todd Lynch from Urbansfreaks, I first discovered this remarkable mansion while researching Manhattan’s remaining private homes. Walking along Fifth Avenue toward 82nd Street, its red-brick facade and pale limestone details immediately stood apart from the surrounding modern towers.
Standing near the entrance felt like stepping into another era, when grand residential architecture defined the avenue. That striking contrast between historic craftsmanship and modern Manhattan is what makes this home so fascinating.
The Exterior Architecture
The facade mixes red brick with limestone trim, a signature Beaux-Arts pairing. The design follows an Italian Renaissance palazzo layout, built by the firm Welch, Smith & Provot.
Tall arched windows run along the lower floors. A mansard roof caps the building near the top. Wrought iron detailing frames the entrance gate, adding weight to the historic feel.
Inside Carlos Slim House New York: Interior and other Features
A rare look inside the billionaire’s $80 million Fifth Avenue mansion, its marble rooms, grand staircase, and hidden Mexico City home
Enterance
Step past the doors and a grand staircase greets you, rising through the Carlos Slim House New York. The listing describes soaring ceilings and hand-carved wood paneling throughout the entry level. Just Like Luxury Mark Cuban House.
Natural light pours in through large windows facing the avenue. The floors carry an old-world polish, consistent with the French Renaissance interior style noted in the original Compass listing.
Living Room
The main living areas keep their early-1900s character at Carlos Slim House New York. Marble fireplaces anchor several rooms. Ornate plaster moldings run along the ceilings, and gold-leaf trim decorates some fixtures.
Large windows offer views of Central Park and the Met. The rooms were designed for entertaining on a grand scale, matching the home’s original use by the Duke family.
Dining Area
Public listing photos of the dining spaces have never been widely released. What is known is that the home was built for formal entertaining, with room sizes suited to large seated dinners.
Given the home’s French Renaissance detailing elsewhere, the dining spaces likely share the same carved paneling and high ceilings found on the entry level.
Kitchen
Interior kitchen photos were never made public in any of the listings at Carlos Slim House New York. Real estate coverage from Forbes, 6sqft, and CNBC focused on the home’s grand public rooms rather than the kitchen.
Given the size of the property, at 20,000 square feet, the kitchen is expected to support the scale of formal entertaining the home was originally built for.
Bedrooms
The Carlos Slim House New York holds eight bedrooms across its upper floors, reached by a separate staircase. These floors also open onto a private terrace and rooftop, with direct views of Central Park and the Met.
Beyond the bedroom count, listing agents have not released specific photos of the primary suite, keeping much of the upper floor private.
Bathrooms
The Carlos Slim House New York has ten full bathrooms in total, a large number even for a mansion this size. As with the bedrooms, detailed photos of individual bathrooms were not included in public listings.
The general interior style, marble, carved wood, and ornate trim, suggests the bathrooms likely follow the same Gilded Age detailing found elsewhere in the home.
Home Office/Study
No dedicated home office has been described in any listing or news coverage. The building’s flexible zoning is worth noting here. Compass, the listing broker, has suggested the mansion could convert into a gallery, foundation, or private office space, beyond its current use as a residence.
Saftey And Security
Slim keeps security tight at both properties, though details stay private by design. The Fifth Avenue mansion sits behind a low iron fence with a monitored entrance, standard for landmarked Manhattan townhouses.
His actual home in Lomas de Chapultepec sits inside a gated, patrolled neighborhood known for reinforced privacy.
Home History
Construction began in 1899 and finished in 1901, commissioned for Benjamin Newton Duke, a tobacco and energy industrialist. The Duke family kept the home until 2006, when Tamir Sapir purchased it for around $40 million. New York City granted the building landmark status in 1974. Slim bought it from Sapir in 2010 for $44 million.
Notable Events at the Property
The Carlos Slim House New York has stayed mostly out of the public eye since Slim bought it. Its biggest headlines have come from real estate listings rather than parties or incidents. It was first listed for $80 million in 2015, pulled from the market in 2016, then relisted at the same $80 million price in January 2023, where it remains today.
How Much Is Carlos Slim House Worth?
Slim paid $44 million for the mansion in 2010. He is now asking $80 million, nearly double that price. If it sells at that number, it would set a new record for the most expensive townhouse ever sold in New York City, beating the previous record of $59 million set in 2021 by a townhouse on East 69th Street.
