You know the building. Even if you don't think you do, you definitely do. It’s that massive, shimmering glass tower that looms over Midtown East with a weirdly specific curve at the top. It’s 731 Lexington Avenue, though most locals just call it the Bloomberg Tower.
It's huge.
But honestly, it’s more than just an office for a media mogul or a place where people buy overpriced salad on their lunch break. It represents a very specific era of New York City ambition. It's where big-tech-energy meets old-school real estate hustle. If you’ve ever walked past the Beacon Court—the circular open-air courtyard in the middle—you’ve felt that strange, vacuum-sealed quiet that only exists in the world’s most expensive zip codes.
Most people just see a skyscraper. I see a fascinating case study in how we live, work, and spend money in 2026.
The Architectural Ego of 731 Lexington Avenue
César Pelli was the mastermind here. If that name sounds familiar, it’s because the guy basically defined the skyline of the late 20th and early 21st centuries. He did the Petronas Towers. He did the Brookfield Place (formerly World Financial Center). With 731 Lexington Avenue, he wasn't just trying to make a tall box. He was trying to solve a puzzle.
The site used to be the flagship Alexander’s department store. When that closed, the plot of land was basically a golden ticket. But here’s the kicker: it’s a mixed-use building. That sounds like boring developer-speak, but it’s actually why the building looks so distinct.
The bottom half? Offices. Specifically, the global headquarters for Bloomberg L.P.
The top half? One Beacon Court. Ultra-luxury condos.
Because the needs of a billionaire living in a penthouse are wildly different from a software engineer working a 12-hour shift, the building has two separate souls. The office floors have massive, open floor plans. We're talking about huge swaths of space with almost no columns. Then, as you move up, the building tapers. It gets slimmer. It gets more private.
It's basically a vertical city. You can tell where the offices end and the apartments begin just by looking at the glass. The curtain wall changes. It's subtle, but once you see it, you can't unsee it.

That Famous Elliptical Court
Let’s talk about Beacon Court. It’s the "doughnut hole" in the middle of the block. Most NYC buildings take up the whole footprint or have a tiny plaza out front. 731 Lexington Avenue invites you in, but only sort of. It’s a privately owned public space (POPS).
You can walk through it to get from 58th to 59th Street. It’s a shortcut. But it’s a shortcut lined with high-end glass and steel. Looking up from the center of that oval is one of the coolest, most vertigo-inducing views in Manhattan. It feels like being at the bottom of a very expensive well.
The lighting design there is intentional. It’s meant to evoke the feeling of a grand European courtyard, but filtered through a Matrix-esque lens. It’s sharp. It’s cold. It’s undeniably New York.
Living at One Beacon Court
If you want to live at 731 Lexington Avenue, you’re not just looking for a place to sleep. You’re looking for a status symbol that happens to have a kitchen.
The residential portion starts on the 30th floor. Why? Because in New York, anything below the 30th floor is basically "the basement" for the ultra-wealthy. You want to be above the noise. You want to see the Atlantic Ocean on a clear day and the Central Park reservoir every morning.
The interiors were originally handled by Jacques Grange. He’s the guy who has designed homes for Yves Saint Laurent and Princess Caroline of Monaco. So, yeah, it’s not exactly IKEA. We’re talking about hardwood floors that cost more than most people's cars and windows that are floor-to-ceiling, wrap-around masterpieces of engineering.
There’s a legendary story about the late Beyoncé and Jay-Z looking at property here, or various hedge fund titans swapping units like Pokémon cards. It’s that kind of place. The 105 units are notoriously difficult to get into, not just because of the price tag—which usually starts in the mid-millions and rockets up to $50 million-plus for penthouses—but because the board is, let's say, discerning.
One of the weirdest perks? The concierge service isn't just a guy who holds your mail. It’s historically been linked to Cempel, providing the kind of "nothing is impossible" service that makes the movie The Continental look like a budget motel. Need a private jet to Ibiza by 4:00 PM? They’ve probably done it before lunch.

The Bloomberg Factor
You can't discuss 731 Lexington Avenue without talking about Mike Bloomberg. When Bloomberg L.P. moved in, they didn't just rent space; they defined the building's identity.
The office design is famously "open." No private offices. Not even for the top executives. It’s all about transparency and "the terminal." If you’ve ever seen a Bloomberg Terminal, you know it looks like something out of a 1980s hacker movie, but it basically runs the world’s economy. Thousands of those things are humming inside this building.
The snack bars are also legendary. If you work there, the food is free. But it’s not just snacks; it’s a curated experience designed to keep you in the building. Why leave for coffee when you have a world-class barista on the 6th floor? It creates this intense, high-pressure, high-reward ecosystem.
It’s a massive driver of the Midtown East economy. When thousands of high-earners descend on one block every day, the surrounding businesses change. The retail at the base reflects this. You’ve got the Container Store (for the organized elite) and formerly, Home Depot—which always felt like a weird fit until you realized how many contractors were constantly renovating the multi-million dollar apartments upstairs.
What Most People Miss About the Engineering
Building something this heavy over a subway line is a nightmare.
Seriously.
The N, R, and W trains are right there. The engineering required to dampen the vibrations so that a billionaire doesn't feel the 6:02 PM express train while they're sipping 30-year-old scotch is mind-blowing. The building uses massive tuned mass dampers and specialized structural steel to stay rigid yet flexible.
And then there's the glass. It's not just "windows." It’s high-performance, low-E coated glass designed to handle the insane wind loads that come with being 800 feet in the air. On a windy day, a building this size can sway several inches. You won't feel it, but the building is "breathing."

Why It Still Matters in 2026
The "office apocalypse" was supposed to kill buildings like this. After the world shifted to remote work, everyone thought these glass towers would become expensive birdhouses.
They were wrong.
What we've seen is a "flight to quality." Companies don't want mediocre office space anymore. If they’re going to force employees to commute, the office has to be better than their living room. 731 Lexington Avenue is the gold standard for that. It’s a "trophy building."
It’s also a landmark of the Bloomberg legacy. Whether you love or hate his politics, his impact on the physical fabric of New York is undeniable, and this building is his North Star. It’s a monument to data, finance, and the idea that being in the center of the action still carries weight.
The Realistic Downsides
It’s not all sunshine and views. Living or working at 731 Lex means dealing with the absolute chaos of Midtown traffic. 59th Street is a parking lot about 18 hours a day. The wind tunnel effect in the winter around the base of the building can literally knock you over.
And then there’s the privacy aspect. Because it’s so famous, there are always tourists taking photos of the courtyard. If you’re a celebrity living in One Beacon Court, you’re basically living in a fishbowl, albeit a very high-end, tinted fishbowl.
How to Experience 731 Lexington Avenue Yourself
You don't need a $10 million bank account to appreciate the space. Here is how you actually "do" 731 Lex like a local:
- The Beacon Court Shortcut: Don't just walk around the block. Walk through the courtyard. Enter on 58th and exit on 59th. Stop in the middle. Look straight up. It’s one of the best free architectural thrills in the city.
- The Retail Peek: Go into the retail spaces at the base. Even if you aren't buying a $500 organization system at the Container Store, it gives you a sense of the scale of the floor plates.
- Night Viewing: See it at night from a few blocks away. The way the top of the building glows is different from the Empire State Building or the Chrysler. It’s a modern, cool white light that feels very "future of the city."
- The Food Scene: While the building's internal food is private, the surrounding blocks have evolved because of the tower. Hit up the spots on 2nd or 3rd Avenue that cater to the Bloomberg crowd—the quality is usually high because the customer base is demanding.
731 Lexington Avenue isn't just a skyscraper. It’s a 1.3 million-square-foot reminder that New York always builds "up" when it runs out of "out." It’s a blend of corporate power and domestic luxury that shouldn't work, but somehow, in the chaos of Manhattan, it makes perfect sense.
If you're planning a visit or just passing through, take five minutes to stand in the court. Forget your phone. Just look at how the glass meets the sky. It's one of those rare spots where you can actually feel the pulse of the city's wealth and ambition vibrating in the walls.
Actionable Insights for Navigating the Area:
- Avoid the 59th Street Bridge rush: If you're visiting the building, do not try to take a cab between 4:00 PM and 7:00 PM. The traffic coming off the bridge makes the 731 Lex block a gridlock zone. Take the 4, 5, or 6 train to 59th St/Lexington Ave instead; the station exit is practically at the building’s front door.
- Photography Tip: For the best shot of the tower's "crown," head over to Central Park’s Sheep Meadow. The perspective from the park allows you to see how the building sits in the skyline far better than you can from the street level.
- Check the POPS hours: While Beacon Court is a public space, it is subject to "reasonable" closures for maintenance. Generally, it’s open during daylight hours, but don't expect to loiter there at 3:00 AM without a security guard asking questions.
