Walk past the intersection of Watts and Grand Streets, and you’ll see it. It’s a massive, hulking presence that somehow manages to look both historic and futuristic at the exact same moment. We are talking about 100 6th Ave New York NY, a building that most locals still refer to as the One Soho Square South tower. It isn’t just another glass box in a city full of them. Honestly, it’s a masterclass in how you take a 1904 warehouse and glue it—literally—to a 1920s neighbor to create something entirely new.
You’ve probably seen the penthouse. It’s that glowing lantern-like structure that sits atop the skyline, visible from blocks away. But the real story isn't just the architecture; it's the sheer gravity this address has in the Manhattan commercial real estate world. When people talk about "Class A" office space in Soho, this is the benchmark. It’s where huge tech brands and media giants go when they want to prove they’ve arrived without looking like they’re trying too hard in a Midtown skyscraper.
The Architecture of 100 6th Ave New York NY: A Weirdly Perfect Marriage
The building is a hybrid. That’s the simplest way to put it.
Back in the day, these were two separate entities: 100 Sixth Avenue and 161 Avenue of the Americas. Around 2017, the developers at Stellar Management and Rockpoint Group decided to do something pretty audacious. They didn't want to tear them down. Instead, they stripped them to their bones and linked them together with a brand-new, central core. This move added about 764,000 square feet of high-end office and retail space to the neighborhood.
It was a massive gamble.
Gensler, the architecture firm behind the project, had to figure out how to make floor plates from the early 20th century work for 21st-century internet speeds and open-concept offices. They succeeded by leaning into the industrial grit. You get these soaring 12-to-14-foot ceilings. You get massive windows that actually let the light in—which, if you’ve ever worked in a dank New York basement office, feels like a religious experience.
The most striking feature? The terraces.
There are about 15 separate outdoor areas scattered throughout the structure. In a city where "outdoor space" usually means a cramped fire escape, having a legitimate garden terrace on your office floor is the ultimate flex. It changes how people work. It changes how they feel about being at 100 6th Ave New York NY on a Tuesday afternoon when the sun is hitting the Hudson River just right.

Why Tech and Media Flocked Here
Location matters, but the vibe matters more.
Soho used to be the land of artists and loft-dwelling rebels. Then it became a giant outdoor mall. Now, it’s transitioning into a hub for "creativity at scale." You see companies like Flatiron Health or Aetna taking up massive amounts of space here because the building offers something Midtown can't: soul.
The lobby at 100 6th Ave New York NY feels more like a boutique hotel than a corporate headquarters. It’s got that dark, moody aesthetic with high-end finishes that says, "We have venture capital, but we also like art."
The Google Effect and the Neighborhood Shift
You can't talk about this address without mentioning the "Google-ization" of the Hudson Square and Soho border. With Google’s massive campus nearby at St. John’s Terminal, the property values at 100 6th Ave New York NY stayed resilient even when other parts of the city’s office market were shaky.
People want to be near the action.
Being at this specific address means you’re steps away from the best espresso in the city and about five minutes from the West Side Highway. It’s a pivot point. If you’re a CEO, you want your employees to want to come to the office. Giving them a rooftop deck with 360-degree views of the Statue of Liberty and the Empire State Building is a pretty good way to ensure they show up.
What Most People Miss About the "One Soho Square" Identity

Technically, it’s both.
One Soho Square is the marketing name for the combined complex. But 100 6th Ave New York NY is the heart of the southern portion.

The building sits on a site that has seen the transformation of New York from a manufacturing powerhouse to a digital one.
The retail at the base of the building also anchors the street. You’ve seen the high-end shops and the foot traffic. It’s not the quiet, cobble-stoned Soho of the 1970s. It’s loud. It’s fast. It’s expensive.
The Real Cost of Doing Business Here
Let's be real for a second. Rents at 100 6th Ave New York NY are not for the faint of heart.
We are talking about some of the highest price-per-square-foot numbers in the district. But companies pay it because of the efficiency. The way the renovation was handled allowed for massive, open floors that aren't interrupted by a forest of support columns. In old buildings, you’re usually fighting the architecture. Here, the architecture is working for you.
