Walk down Greenwich Street today and it’s easy to get overwhelmed by the sheer scale of the new World Trade Center complex. You’ve got the massive, needle-like spire of One World Trade grabbing all the postcards, and the ribbed, skeletal Oculus drawing in the tourists with their cameras. But if you actually work in Lower Manhattan, or if you’re a fan of architecture that doesn't try too hard to scream for attention, your eyes usually settle on 150 Greenwich Street.
Most people know it simply as 4 World Trade Center.
It's a glass monolith. But it’s a weirdly polite one. Depending on the weather or the time of day, the building basically disappears into the sky. Fumihiko Maki, the Pritzker Prize-winning architect behind the design, didn't want a loud building. He wanted a "quiet" one. Honestly, in a neighborhood defined by the heavy weight of history and the aggressive verticality of Wall Street, that quietness feels like a relief.
The Rebirth of 150 Greenwich Street
We should probably clear something up right away: the 150 Greenwich Street of today is not the 4 World Trade Center of the 1970s. The original was a nine-story low-rise that felt more like a functional appendage to the Twin Towers than a landmark in its own right. It was destroyed during the September 11 attacks. When the master plan for the new site was being hashed out by Daniel Libeskind and the Silverstein Properties team, the goal for "Tower 4" was to create a dignified presence that respected the Memorial while providing top-tier office space.
It opened in November 2013. It was actually the first tower on the original 16-acre site to officially open for business. Think about that for a second. While everyone was watching the slow progress of the Freedom Tower, 150 Greenwich Street was quietly getting the job done.
What’s Actually Inside?
You’d think a building this sleek would be filled with nothing but high-frequency trading firms and hedge funds. Not really.

The Port Authority of New York and New Jersey takes up a huge chunk of the square footage here. They moved their headquarters into the building, occupying about 600,000 square feet. Then you’ve got the City of New York taking up another massive block of space. It’s a mix of government pulse and private enterprise.
Spotify is a big tenant too. They moved their US headquarters there a few years back, taking over multiple floors. It creates this strange, cool vibe where you have suit-and-tie government employees sharing elevators with people in hoodies and sneakers who are literally deciding what the world listens to on their morning commute.
- Total Height: 977 feet (roughly 298 meters).
- Floor Count: 72 stories above ground.
- Retail Space: The bottom floors connect directly to the Westfield World Trade Center mall.
- Floor Plates: They change shape. The lower floors are shaped like a parallelogram, following the street grid, but as the building rises, it twists into a trapezoid. This isn't just for looks; it angles the building to face the Memorial and the harbor.
Why the Architecture Matters (And It’s Not Just Glass)
If you look at the building from the Memorial plaza, you'll notice the reflection. The glass is highly silvered. On a clear day, the tower reflects the sky and the trees of the park so perfectly that the corners almost seem to vanish. Maki used what’s called "ultra-clear" glass with a high-performance coating.
It’s LEED Gold certified. That’s a big deal for a building of this scale. The HVAC systems are incredibly efficient, and they use a massive gray-water recycling system. Basically, the building collects rainwater to help run the cooling towers and irrigate the local greenery. It’s smart engineering that most people never see.
The lobby is another story. It’s minimalist. Like, really minimalist. Huge walls of black granite, high ceilings, and a massive art installation by Kozo Nishino called "Sky Memory." It’s a large titanium ring that looks like it’s floating. It’s the kind of space that makes you want to whisper, even if you’re just there to grab a coffee at the retail level.

Getting There and Getting Around
The location is basically the center of the transit universe in NYC. Because 150 Greenwich Street is integrated into the World Trade Center Transportation Hub, you can get to almost any subway line without even stepping outside.
You’ve got the A, C, E, J, Z, 2, 3, 4, 5, R, and W trains right there. Plus the PATH train to New Jersey.
If you’re coming in for a meeting or just visiting the area, the entrance is on Greenwich Street, bounded by Liberty, Church, and Cortlandt Streets. It sits right across from the South Pool of the National September 11 Memorial. This proximity gives the office views that are—frankly—some of the most sobering and beautiful in the city. You aren't just looking at a park; you’re looking at history.
The Reality of Working in a High-Security Zone
Living or working around the World Trade Center comes with baggage. There’s no point in pretending it doesn't.
Security is tight. You don't just "wander" into 150 Greenwich Street. There are bollards, NYPD presence, and a very sophisticated lobby check-in system. For the companies that lease space here, that's a feature, not a bug. They want that level of safety.

But it also means the area can feel a bit "sanitized" compared to the grit of the East Village or the chaos of Midtown. Everything is polished. Everything is clean. It’s a specific version of New York that feels very 21st-century.
A Note on the Surroundings
If you’re in the area for the first time, don’t just stare at the tower.
- The Oculus: Right next door. Go inside for the architecture, stay for the high-end shopping.
- Eataly: Located in 4 World Trade (the same building!). It’s on the third floor. It’s one of the best places in the neighborhood to grab a quick espresso or a massive plate of pasta with a view of the memorial.
- Liberty Park: Just to the south. It’s an elevated park that gives you a great perspective on the building’s facade and its relationship with the rest of the site.
Actionable Takeaways for Visitors and Professionals
If you’re looking at 150 Greenwich Street for office space or just planning a visit to the Financial District, keep these things in mind:
- For Business: The floor plates are column-free. If you’re a tenant, this is huge. It means you can design an open-concept office without having to work around giant concrete pillars. It’s why tech companies like Spotify love it.
- For Tourists: You can’t go to an "observation deck" here. One World Trade is for that. However, you can access the retail levels and Eataly without needing a badge. The views from the Eataly dining area are worth the price of a panini.
- For Architecture Buffs: Pay attention to the "notch" on the upper floors. As the building changes shape, it creates a specific silhouette that makes it look different from every angle. It’s a masterclass in subtle geometry.
- Logistics: If you have a meeting here, give yourself an extra 10 minutes for security. The visitor management system is efficient, but the lines can get long during the morning rush.
The building at 150 Greenwich Street isn't trying to be the tallest or the flashiest. It’s designed to be a mirror—literally and figuratively—reflecting the resilience of a neighborhood that has seen the absolute worst and is now showing the absolute best of modern urban design. It’s a functional, elegant piece of the skyline that finally feels like it belongs.
