Walk out of the Oculus and look up. You’ll see it. While One World Trade Center gets all the postcards and the "Freedom Tower" nicknames, the building at 175 Greenwich Street—better known as 3 World Trade Center—is actually the one doing the heavy lifting for the neighborhood's soul. It’s a 1,079-foot glass giant. Huge. But it’s also weirdly transparent. Designed by Richard Rogers (the same legend behind the Pompidou Center), it has this external diamond-shaped bracing that makes it look like it’s wearing an exoskeleton.
Most people just walk past it on their way to the 9/11 Memorial. That’s a mistake. Honestly, if you want to understand how New York actually rebuilt itself after 2001, you have to look at this specific plot of land.
It wasn't easy to get this thing off the ground. At all. For years, it was just a "stump." Literally. Because of financing drama and the 2008 crash, the Port Authority and Silverstein Properties basically hit pause. They built the foundation and the first few floors, then waited. It sat there, a concrete reminder of a stalled dream, until GroupM signed a massive lease that finally kickstarted the vertical climb.
The Architecture of 175 Greenwich Street
The design is intentional. It’s not just a box. Rogers Stirk Harbour + Partners wanted it to "celebrate" the verticality. You’ve got these massive floor-to-ceiling windows that are actually clear—not that murky green glass you see on older skyscrapers.
The coolest part? The corners. They are column-free. Because the building uses that external "K-brace" steel system, the interior corners are wide open. If you’re an intern at a big ad agency on the 50th floor, you’re looking out at a 360-degree panorama of the Hudson River and the city skyline without a single piece of steel blocking your view. It’s a flex. It really is.
But it’s also built like a fortress. After 2001, the safety standards for the World Trade Center site became the strictest in the world. We’re talking concrete-encased elevator cores that are basically indestructible. The stairs are extra wide to allow for two-way traffic during emergencies. It’s the kind of stuff you hope nobody ever needs, but it’s baked into the DNA of the building.

The Terrace Game is Strong
If you’re lucky enough to work there, or know someone who does, you know about the terraces. 175 Greenwich Street features several outdoor decks. The biggest one is on the 17th floor, but there are others higher up. In a city where "outdoor space" usually means a cramped fire escape, having a massive garden terrace overlooking the Memorial pools is a game-changer for office morale.
It’s about the integration with the street. The base of the building is filled with retail. It doesn't feel like a gated community for billionaires. You have shoppers, commuters, and tourists all swirling around the ground floor. It’s chaotic. It’s New York.
Who Actually Lives (Well, Works) Here?
This isn't just a building; it’s a vertical economy. When it opened in June 2018, it signaled a shift. Lower Manhattan used to be just suit-and-tie finance guys. Wall Street. Boring.
Now? It’s different.
- GroupM: They took a massive chunk of the building. We’re talking hundreds of thousands of square feet.
- Uber: Yeah, they moved in too. They have a massive presence here, occupying several floors.
- Diageo: The people who make Guinness and Johnnie Walker. They moved their North American headquarters here from Connecticut.
- Hudson River Trading: A high-frequency trading firm that needs the insane tech infrastructure the building provides.
The mix is intentional. Larry Silverstein, the developer, wanted to move away from the "banking only" vibe. He wanted tech, media, and creative types. And it worked. The building is almost entirely leased out, even in a post-pandemic world where people are weird about offices. Why? Because the amenities are better than your living room.

What Most People Get Wrong About the Site
A lot of people think the whole World Trade Center complex is one big government project. Nope. While the Port Authority of New York and New Jersey owns the land, 175 Greenwich Street is a private-public partnership. Silverstein Properties has the 99-year lease.
There was a huge debate about the height, too. Originally, it was supposed to have these four decorative "spires" or masts at the top that would have made it even taller. Those were scrapped. Some critics were annoyed, saying it made the building look "unfinished." Honestly, though? The flat roof works. It lets One World Trade Center be the "tall one" while 3 WTC acts as the sophisticated middle sibling.
Sustainability that Actually Matters
People throw around "LEED Gold" like it’s a participation trophy. But for a building this size, the environmental tech is actually impressive.
The glass has a special coating to reduce heat gain, so the AC doesn't have to work as hard. They collect rainwater to use in the cooling towers. Even the elevators use "regenerative braking"—they actually generate electricity when they slow down, which is then fed back into the building’s grid. It’s smart engineering that saves millions in the long run.
Why 175 Greenwich Street Still Matters in 2026
We're currently seeing a "flight to quality." Old, dusty office buildings on midtown side streets are dying. Companies don't want them. But buildings like 175 Greenwich Street are thriving.

The air filtration is top-tier. The touchless technology is everywhere. The location—literally on top of a transit hub where 12 subway lines and the PATH train converge—is unbeatable. You can get here from Jersey City or Brooklyn in twenty minutes. In the world of commercial real estate, that’s the "holy grail."
It’s also about the view of the future. When you stand at the base of 175 Greenwich, you’re looking at the most expensive real estate development in American history. It represents a $20 billion bet on the idea that people still want to gather in person.
Tips for Visiting or Navigating the Area
If you're heading down there, don't just look at the building from the outside.
- Enter through the Oculus: Take the underground passages. It’s like being in a sci-fi movie. You can walk from the subway directly into the lobby of 3 WTC without ever stepping outside in the rain.
- Check the Retail: The shops at the base are part of the Westfield World Trade Center mall. It’s high-end, but there are decent coffee spots if you just need a break.
- The Evening Glow: Go at sunset. The way the light hits the floor-to-ceiling glass on the western face is incredible. The building basically turns into a giant mirror for the sunset over the Hudson.
- Photography: If you’re trying to get a shot of the whole building, don’t stand right next to it. Go across the street to Zuccotti Park or stand near the entrance of 4 WTC. You need the distance to capture the "K-bracing" details.
The Bottom Line
175 Greenwich Street isn't just an address. It’s a 2.5 million-square-foot statement of resilience. It survived the Great Recession, a decade of construction delays, and a global shift in how we work. It’s the anchor of the new Downtown.
Whether you're a business looking for a flagship office or just a tourist trying to make sense of the skyline, this building is the key. It’s modern New York: transparent, tough, and incredibly expensive.
Actionable Next Steps
- For Business Owners: If you're looking for office space, look into the smaller pre-built suites often available in the mid-rise section; they offer the same perks as the anchor tenants but for smaller footprints.
- For Visitors: Use the "3 WTC" entrance to access some of the best retail tucked away from the main tourist crush in the Oculus.
- For Architecture Buffs: Study the "load-sharing" mechanics of the external steel; it's one of the few skyscrapers in the world where the structural "skeleton" is actually part of the aesthetic.
- For Commuters: Remember that the PATH entrance at the base of the building is often less crowded than the main central terminal entrances during peak hours.
