You’ve seen it from the street. If you’ve ever walked through Madison Square Park, you’ve definitely looked up at that massive Art Deco limestone beast and wondered what exactly goes on inside. It’s a block-long monolith. It’s imposing. Honestly, 11 Madison Ave New York NY 10010 is one of those rare buildings that manages to feel like both a relic of old-school Manhattan power and the nerve center of the modern tech world all at once.
Most people just call it the MetLife Building—or rather, the old MetLife Building, before they moved across the park. But today, it’s basically the headquarters of some of the most influential companies on the planet.
It’s huge.
The building spans an entire city block between 24th and 25th Streets. We're talking about 2.3 million square feet of prime real estate. If you tried to walk the perimeter, you’d realize just how much space that actually is in the context of Flatiron. It doesn't just sit there; it looms.
The Weird History of the "Tower That Never Was"
Here is the thing about 11 Madison Ave New York NY 10010 that most people actually get wrong: it was supposed to be the tallest building in the world. Seriously. In the late 1920s, the Metropolitan Life Insurance Company had these grand, almost ego-driven plans to build a 100-story skyscraper. They wanted to dwarf everything else in the skyline.
Then 1929 happened.
The Great Depression hit, the stock market crashed, and suddenly, building a 100-story tower seemed like a terrible financial move. So, they just... stopped. They finished the first 30 floors and capped it off. That’s why the building looks so incredibly "sturdy" and wide at the base. It was engineered to support the weight of a massive tower that was never actually built. If you look at the exterior today, those deep setbacks and that heavy Art Deco styling make a lot more sense when you realize it’s essentially a giant pedestal for a ghost tower.
Architects Harvey Wiley Corbett and D. Everett Waid were the brains behind it. They went for that classic North Italian Renaissance meets Art Deco vibe. It’s got these gorgeous arched entrances and a lobby that feels like a cathedral of capitalism. Marble everywhere. Bronze accents. It’s the kind of place where you feel like you should be wearing a tailored suit just to walk through the revolving doors.

Who Actually Works There Now?
If you walk in today, you aren't seeing insurance agents from the 1930s. You’re seeing engineers from Google and financiers from Credit Suisse.
SL Green Realty Corp, the massive real estate investment trust, bought the building back in 2015 for roughly $2.28 billion. At the time, it was one of the largest single-asset real estate transactions in New York City history. They didn't just buy a building; they bought a cash cow.
The Google Connection
Google is the elephant in the room. They’ve been aggressively scooping up space in the Chelsea and Flatiron areas for years. While their main hub is over at 111 Eighth Avenue, they take up a massive chunk of 11 Madison. It’s funny because you have this ultra-modern, data-driven tech giant operating inside a building designed before the invention of the transistor. It’s a weird contrast.
Finance and More
Credit Suisse has been a long-term anchor tenant here too. They basically occupy the middle section of the building. Then you have Sony, which moved its US headquarters into the building several years ago, taking over the top floors. It’s a weirdly diverse ecosystem of old-school finance, global media, and Big Tech.
- Sony Music Entertainment has some incredible views of the park from up there.
- Yelp used to be a major presence, though office footprints in NYC have been shifting lately.
- Credit Suisse (now part of UBS) has historically held hundreds of thousands of square feet.
Eleven Madison Park: The World's Most Famous Restaurant?
We can’t talk about 11 Madison Ave New York NY 10010 without talking about the restaurant on the ground floor. Eleven Madison Park (EMP).
If the building is the body, EMP is the heart. Chef Daniel Humm took a massive risk a few years ago by turning the entire menu vegan. People thought he was crazy. "You can't have a three-Michelin-star restaurant in Manhattan without foie gras or lobster," they said. Well, they were wrong. It’s still one of the hardest reservations to get in the world.
The dining room is cavernous. High ceilings. Floor-to-ceiling windows looking out onto Madison Square Park. It’s high-stakes dining. It’s also a perfect example of how this specific address caters to the global elite. You have billionaires upstairs making deals and foodies downstairs spending $400 on a tasting menu. It’s a very specific kind of New York energy.

Why the Location Is Untouchable
The 10010 zip code is basically the sweet spot of Manhattan. You’re right on the edge of the Flatiron District and NoMad.
Transit-wise, it’s a dream. You have the 6 train right there at 23rd Street. The N, R, and W are a block away. You can get to Grand Central or Union Square in minutes. But more than the transit, it’s the park. Madison Square Park is arguably the best-maintained park in the city. It’s got the original Shake Shack, incredible rotating art installations, and it provides a "lung" for the neighborhood that keeps the area from feeling like a concrete canyon.
Honestly, the park is the reason the building is so valuable. Every window on the western facade has an unobstructed view of the greenery and the Flatiron Building. You can't buy that kind of light and air in Midtown anymore.
The Logistics: What You Need to Know
If you’re actually looking to visit or do business at 11 Madison Ave New York NY 10010, keep a few things in mind.
First, security is tight. This isn't a public mall. Unless you have a meeting at Sony or a reservation at EMP, you aren't getting past the lobby desks. The lobby itself is worth a peek if you can sneak a glance, but don't expect to wander the halls.
Second, the loading docks are on the side streets. If you’re a courier or making a delivery, 24th and 25th Streets are where the action happens. It’s a constant dance of box trucks and Sprinter vans.
Sustainability is also a thing now.
Even though the building is nearly a century old, SL Green has poured millions into retrofitting it. They've updated the HVAC systems and improved energy efficiency. It’s a LEED Gold certified building. That’s actually really hard to achieve with a structure this old and this large. It shows that even these limestone giants can adapt to the 21st century.

Common Misconceptions About 11 Madison
People often confuse this building with the New York Life Building (the one with the gold pointy roof) or the MetLife Tower (the one that looks like a clock tower).
- The Clock Tower: That is 1 Madison Ave. It’s right next door. It’s beautiful, but it’s a totally different vibe.
- The Gold Roof: That’s the New York Life Insurance Building at 51 Madison Ave.
- 11 Madison: This is the big, blocky, square one. It doesn't have a spire. It doesn't have a clock. It just has presence.
It’s also not "just an office building." Because of Eleven Madison Park and the various events held in the building’s upper-level spaces, it’s a cultural landmark. It’s been featured in countless movies and TV shows whenever a director needs a shot that screams "Big New York Business."
Practical Insights for the Area
If you find yourself heading to 11 Madison Ave New York NY 10010 for a meeting or just to explore the neighborhood, here is how to handle it like a local.
Skip the generic coffee carts. Walk a few blocks over to Eataly on 23rd Street if you want decent espresso, or hit up Birch Coffee on 27th. For a quick lunch that isn't a $300 sit-down affair, the neighborhood is packed with options. Num Pang Kitchen is great for Cambodian sandwiches, and obviously, the Shake Shack in the park is a classic—though the line is usually a nightmare during tourist season.
If you’re looking at the building from a real estate or investment perspective, keep an eye on the tech sector's "return to office" trends. While some firms are downsizing, 11 Madison remains a "trophy" asset. Companies want to be here because the address carries weight. It’s a prestige move.
Next Steps for Visitors and Professionals:

- For Foodies: If Eleven Madison Park is out of your budget, try The Clocktower nearby in the Edition Hotel. It offers a similar "grand New York" vibe with a slightly more accessible price point.
- For Commuters: Use the 23rd St station on the 6 line for the most direct access, but be prepared for heavy foot traffic during morning rush hour (8:30 AM – 9:30 AM).
- For History Nerds: Visit the NYC Landmarks Preservation Commission website to look up the original 1930s floor plans. Seeing what the building could have been is a fascinating look at "what if" history.
