If you’ve ever found yourself wandering around Midtown Manhattan, specifically that high-energy stretch between 5th and 6th Avenues, you've likely walked past 51 W 51st St New York NY without even realizing you were standing in front of a piece of corporate history. Most people just call it the 1285 Avenue of the Americas building, or the UBS Building. It's huge. It's imposing. It basically screams "Old School New York Finance."
But honestly, the address 51 W 51st St is the back door. It’s the discrete entrance. While the tourists are busy taking selfies at Rockefeller Center right across the street, the real business—the kind involving billions of dollars and high-stakes law—is happening right here.
What is 51 W 51st St New York NY exactly?
Technically, this is the northern entrance to the massive office tower that occupies the entire block between 51st and 52nd Streets. It was built back in 1960. Think Mad Men era. Skidmore, Owings & Merrill (SOM) designed it, and they didn't do "cozy." They did "grand." When you walk into the lobby from the 51st Street side, you aren't greeted by a tiny reception desk. You’re greeted by massive open spaces and a sense that you should probably be wearing a suit, even if you’re just there to deliver lunch.
It’s a 42-story skyscraper. It’s got about 1.7 million square feet of space. That is a staggering amount of real estate for one of the most expensive zip codes on the planet.
The building is owned by a partnership involving institutional heavyweights, and for years, UBS has been the name most associated with it. They have their North American headquarters here. But it’s not just bankers. Some of the most powerful law firms in the world, like Paul, Weiss, Rifkind, Wharton & Garrison, have spent decades inside these walls. If you’re a corporate lawyer in NYC, 51 W 51st St is basically a second home.
The location is the actual flex
Let's talk about why companies pay astronomical rents to stay at 51 W 51st St New York NY. It’s the proximity. You are literally seconds away from the B, D, F, and M subway lines. You can walk out the door and be at the Radio City Music Hall stage door in three minutes.

You’re also surrounded by the "power lunch" circuit. The area isn't exactly known for cheap eats, but if you're looking to close a deal, you have the 21 Club (rest in peace, mostly) nearby and plenty of high-end steakhouses. It’s the epicenter of Manhattan’s business district.
Why 51 W 51st St is shifting its identity
Things are changing. The pandemic shifted how people look at Midtown. For a while, people thought these massive towers would become ghost towns. They didn't. Instead, they got fancy.
The owners of 1285 Avenue of the Americas (the main identity of 51 W 51st St New York NY) have poured millions into renovations. We're talking upgraded lobbies, better elevators, and a massive focus on sustainability. Why? Because firms like Paul Weiss or UBS aren't going to stay in a building that feels like 1985. They want floor-to-ceiling windows, high-tech air filtration, and a lobby that looks like a modern art gallery.
Actually, there is a literal art gallery vibe to the building. The lobby has frequently hosted rotating art installations. It makes the "back door" entrance at 51 W 51st St feel less like a service entrance and more like a private club for the city's elite.
The Real Estate Reality
The occupancy rates here remain surprisingly high. While other parts of the city struggle, the "Sixth Avenue Corridor" holds its own.

- Total Square Footage: ~1,700,000
- Year Built: 1960
- Renovation status: Ongoing/Significant recent upgrades
- Primary tenants: UBS, Paul Weiss, Mizuho
It's a "Class A" building. In real estate speak, that just means it's top-tier. It means the plumbing works, the security is tight, and the views of the Manhattan skyline are actually good enough to justify the price tag.
Misconceptions about the 51st Street entrance
Some people get confused because the building has two primary identities. If you tell a cab driver to go to "1285 Avenue of the Americas," they know exactly where to go. If you say 51 W 51st St New York NY, they might hesitate.
Essentially, 51 W 51st St is the "Side A" to the "Side B" of the main Sixth Avenue frontage. It’s often used for specific tenant entrances or for people trying to avoid the heavy foot traffic of the main avenue. It’s quieter. It’s a bit more "New York secret" despite being attached to a giant glass and steel monolith.
Another thing? People think these buildings are just empty boxes at night. Not true. The cleaning crews, the 24/7 security, and the legal teams working on late-night M&A deals keep the lights on until 3:00 AM. It’s a literal engine of global finance that never actually stops.
How to navigate 51 W 51st St New York NY like a local
If you have a meeting there, don't just show up and expect to wander in. Security is intense. You need a government-issued ID. You will be photographed. You will get a sticker. It’s the standard NYC corporate gauntlet.

But here’s a pro tip: if you’re early, don't just stand in the lobby looking awkward. The building is connected to the Rockefeller Center concourse system. This is a massive underground network of shops and eateries. You can actually walk underground from 51 W 51st St all the way to 47th Street without ever seeing the sun. It’s perfect for rainy days or when the winter wind is whipping off the Hudson River.

The Future of the Address
The lease renewals at 51 W 51st St New York NY are often the subject of major real estate news. When a firm like Paul Weiss considers moving, it makes waves. However, the building has managed to keep its anchor tenants by constantly evolving.
It’s not just about desk space anymore. It’s about "amenitization." Buildings like this are adding gyms, high-end coffee bars, and rooftop terraces to lure workers back into the office. While 51 W 51st St is traditionally more conservative, the pressure to modernize is real.
Honestly, the building is a survivor. It survived the fiscal crisis of the 70s, the 2008 crash, and the recent shift toward hybrid work. It stays relevant because in the world of high finance, location is still king. You want to be where the money is. And the money is definitely at 51 W 51st St.
Actionable Takeaways for Visitors or Professionals
- Check your entrance: Always confirm if your contact wants you at the 6th Avenue entrance or the 51 W 51st St door. They are different lobbies.
- Security prep: Have your ID ready before you reach the desk. It saves everyone's time.
- Use the Concourse: If it's raining, use the underground tunnel system to reach the subway or nearby buildings.
- Explore the Art: Take a moment to look at the lobby installations; they are often museum-quality pieces hidden in plain sight.
- Lunch Strategy: Avoid the 12:30 PM rush. The local spots get slammed by thousands of office workers all at once. Go at 11:45 AM or 1:30 PM.
