Walk out of Grand Central Terminal, dodge a few tourists holding up their phones to capture the Chrysler Building, and head three blocks east. You’ll find yourself standing under the massive blue-glass facade of 622 3rd Ave New York NY 10017. It’s also known as Grand Central Plaza. Honestly, if you work in media, tech, or international advertising, you’ve probably spent more time in this lobby than you’d care to admit. It isn't just another skyscraper. It’s a 1.1 million-square-foot ecosystem that defines how Midtown East actually functions.
People often mistake the area for being just "corporate." That’s a bit of a lazy take. While the address sounds formal, the vibe inside is surprisingly fast-paced and creative. You have massive global agencies like McCann Worldgroup calling this place home. Imagine thousands of people inside one structure trying to solve the world's branding problems while simultaneously worrying about the line at the nearby Joe & The Juice. It’s a literal engine of the New York economy.
The Physicality of 622 3rd Ave New York NY 10017
Build it high. In 1958, that was the mantra. The building was originally designed by Emery Roth & Sons, a name that basically owns the mid-century New York skyline. But it didn't stay stuck in the fifties. Cohen Brothers Realty Corporation, the folks who own it, poured millions into a renovation that swapped out the old-school grit for a polished, modern look. The lobby is huge. It has these soaring ceilings and a glass curtain wall that makes you feel like the city is pouring inside.
The floor plates are interesting. Most buildings in this part of town are cramped. Not here. We are talking about floors that range from 12,000 to 40,000 square feet. If you’re a CEO, that’s the dream because you can actually see your employees without climbing stairs. It’s efficient. It’s also sitting right on top of some of the best transit links in the world. Being at 622 3rd Ave New York NY 10017 means you are a five-minute walk from the 4, 5, 6, 7, and S subway lines, plus Metro-North. Commuters from Westchester love this place for a reason. They can be at their desk by 9:00 AM and back on a train by 5:15 PM without ever breaking a sweat.
Who Actually Works Here?
It’s a mix. A weird, high-powered mix.
The anchor tenant for a long time has been Interpublic Group (IPG) and its various subsidiaries. Think McCann, think specialized marketing firms. These are the people who make the commercials you see during the Super Bowl. When you walk through the revolving doors, you see the "ad person" aesthetic—black turtlenecks, expensive sneakers, and a look of permanent caffeine-induced urgency. But it isn’t just advertising. You’ve got legal firms, financial services, and tech startups that want the prestige of a Third Avenue address without the stuffiness of Park Avenue.

The building also houses the Permanent Mission of various countries to the United Nations. This adds a layer of security and international gravitas that most office buildings lack. You might be sharing an elevator with a graphic designer one minute and a diplomat the next. It creates this specific New York energy where the stakes feel high regardless of what floor you’re getting off on.
The Transit Advantage
Let's be real. Location is everything.
If you are at 622 3rd Ave New York NY 10017, you are positioned in the "Grand Central Submarket." In real estate speak, that’s gold. The proximity to the Chrysler Building and the MetLife Building makes it part of the most iconic cluster of real estate on the planet. But unlike the Chrysler Building, which has those beautiful but tiny, triangular offices, 622 3rd Ave is functional. It’s built for work, not just for postcards.
What Most People Get Wrong About Third Avenue
People think Third Avenue is the "boring" sibling to Madison or Park. They’re wrong.
Third Avenue has undergone a massive transformation. It used to be dominated by the Elevated Train (the "El") until the mid-50s. Once that came down, the area exploded. 622 3rd Ave was part of that first wave of modernism. Today, the area is packed with "Third Avenue Class A" office space. It’s where the actual work gets done while the tourists are busy taking photos on 5th Ave.

There’s also the food situation. Working at 622 3rd Ave New York NY 10017 means you’re surrounded by some of the most diverse lunch spots in Manhattan. You have the high-end steakhouses for client dinners, sure. But you also have the small, hole-in-the-wall delis that have survived four decades of rent hikes. You can get a $20 salad or a $6 bagel within the same block. That’s the real New York.
Sustainability and the Modern Office
You can't talk about Midtown real estate in 2026 without talking about Local Law 97. New York is cracking down on carbon footprints. 622 3rd Ave has had to adapt. The building owners have integrated LEED-certified systems and upgraded HVAC units. It’s not just about being "green" for the sake of the planet—though that matters—it's about the bottom line. Modern tenants won't sign a lease in a building that bleeds heat and wastes electricity.
The windows are another thing. They offer some of the clearest views of the East River and the Empire State Building. If you’re on a high floor, the light is incredible. In a city where many offices feel like caves, the floor-to-ceiling glass at 622 3rd Ave is a massive selling point. It keeps people from burning out. Or at least, it helps.
Navigating the Logistics
If you’re visiting, don’t just wander in. Security is tight, especially with the diplomatic missions on-site. You’ll need a government-issued ID and a reason to be there. The freight entrance is on 40th Street, which is a crucial detail if you’re coordinating a delivery or a move-in. Manhattan logistics are a nightmare, and 40th Street is no exception.
Parking? Forget about it. There are garages nearby, like the one on East 39th, but you’ll pay a king’s ransom. Take the train. Honestly, taking a car to 622 3rd Ave is a rookie mistake. The traffic on Third Avenue during rush hour is a slow-motion disaster.

The Surprising History of the Site
Before the glass tower, this patch of dirt was part of the rapid industrialization of New York. It wasn't always fancy. It was gritty. The transition from industrial warehouses to the "White Collar" paradise we see now happened in the blink of an eye after World War II. 622 3rd Ave represents that shift. It’s a monument to the era when New York decided to become the financial and advertising capital of the world.
Some people complain that these glass boxes lack character. I disagree. The character of 622 3rd Ave comes from the people inside it. It’s the late-night pitches, the diplomatic negotiations, and the thousands of daily interactions that happen in the lobby. It’s a vertical city.
Actionable Insights for Tenants and Visitors
If you are looking at leasing space or just heading there for a meeting, keep these points in mind:
- Audit your commute. If you are coming from the East Side or Westchester/Connecticut, this is peak convenience. If you are coming from deep Brooklyn, it's a bit of a trek, even with the 4/5 train.
- Leverage the neighborhood. Don't just stay in the building. Use the proximity to the University Club or the Yale Club for high-stakes meetings.
- Security is real. Allow an extra 10 minutes for the check-in process. The kiosks are fast, but the lines can get long at 8:55 AM.
- Check the views. If you're negotiating a lease, the eastern-facing views of the river are often "quieter" visually than the western-facing views of the midtown skyscrapers, which can be distracting.
- Use the public plazas. There are small pockets of outdoor space nearby that are essential for mental health breaks during the summer.
622 3rd Ave New York NY 10017 is more than a zip code. It is a strategic vantage point in the most competitive real estate market on earth. Whether you're there to sell a brand, represent a country, or just grab a coffee, you're standing in a place that makes New York tick.
Check the official Cohen Brothers Realty website for current floor availability or contact a tenant rep broker to see if any sublease opportunities exist in the IPG stacks. If you're visiting for a meeting, ensure your host has entered you into the building's visitor management system at least 24 hours in advance to bypass the manual entry lines. For lunch, skip the immediate block and walk two minutes south to find the smaller, non-chain options that offer a better taste of the neighborhood's history.
