You’ve probably walked past 135 W 50th St NYC a dozen times without really looking at it. It’s that massive, unapologetic slab of glass and steel sitting right in the thick of Midtown, sandwiched between the tourist chaos of Rockefeller Center and the suits of Sixth Avenue. But lately, this building has become a bit of a lightning rod for anyone watching the New York City office market crumble—or reinvent itself, depending on who you ask.
Midtown is weird right now.
It’s not just about empty desks. It’s about 135 W 50th St NYC specifically because this address is basically a case study in what happens when a "Class A" property hits a wall. UBS used to be the anchor here. They left. When a giant like that exits, it leaves a hole that isn't easily filled by a coffee shop and a few boutique law firms.
The Reality of 135 W 50th St NYC in a Post-Remote World
So, what is actually going on inside those walls? Honestly, it’s complicated. The building, often referred to as the Onyx Tower, has over 900,000 square feet of space. That is a staggering amount of vertical real estate. George Comfort & Sons, the folks managing the place, have been trying to pull off a massive "amenitization" play. You know the vibe—terraces, gyms, club lounges—the kind of stuff meant to trick you into forgetting you’re at work.
The 135 W 50th St NYC renovation wasn't cheap. We are talking about a $75 million-plus overhaul. They added a 20,000-square-foot tenant amenity center on the second floor called "Club 135." It’s got a bar, it’s got lounge seating, and it’s got those fancy wellness rooms everyone talks about but half the office is too shy to use.
But here is the kicker: high-end perks don't always fix high-end vacancies.
While some tech companies and smaller financial firms have nibbled—like Mazars taking a chunk of space—the building has faced the same headwinds as the rest of the "commodity" office market. If a building isn't brand new (like One Vanderbilt) or historic and charming (like the Chrysler Building), it has to fight tooth and nail for every single lease.
Why Location Is a Double-Edged Sword
Location used to be everything. Being at 135 W 50th St NYC meant you were a three-minute walk from the B, D, F, and M trains. You could hit the Halal Guys cart on 53rd and be back at your desk before your gyro got cold.

That still matters. Sorta.
The problem is that Midtown West is currently competing with Hudson Yards. If you’re a CEO with a massive budget, are you going to put your people in a renovated 1960s tower, or are you going to move them to a shiny new bird-killing glass skyscraper with a shopping mall at the base? 135 W 50th St NYC is fighting that battle every day. It’s a battle of the "good" versus the "new."
The Financial Drama You Won't See on the Plaque
Let's get into the weeds. If you follow the money, 135 W 50th St NYC has had a rough ride with its debt. Back in early 2024, news broke that the $150 million loan on the property was headed toward a bit of a crisis. It was sent to special servicing. For those who don't speak "real estate finance," that’s basically the corporate version of the "check engine" light flashing red while you're on the highway.
It’s not necessarily a death sentence. Special servicing can just mean the owners are renegotiating. But it highlights the precariousness of these mid-block Midtown giants. When occupancy dips below a certain level, the math just stops working.
- The building was roughly 35% vacant at one point during the height of the transition.
- The debt-to-income ratio became a massive headache for the ownership group.
- Competition from "trophy" buildings lured away legacy tenants who wanted more prestige.
People like to think of NYC real estate as this invincible monolith. It's not. It’s a living, breathing, and occasionally bleeding ecosystem. 135 W 50th St NYC is a prime example of a building that is "too big to fail" but "too old to win" without a massive fight.
The Design Shift: Can Glass be Cozy?
Architecturally, 135 W 50th St NYC is a product of its time—built in 1963. The recent lobby renovation by Fogarty Finger was an attempt to soften the blow. They used a lot of warm woods and "hospitality-inspired" lighting. It’s a far cry from the cold, marble mausoleums of the 80s.
Walking into the lobby now, it feels more like a high-end hotel than an insurance headquarters. Does that make you want to work there? Maybe. If you’re a creative agency or a mid-sized law firm looking for a "vibe" without the Hudson Yards price tag, it’s actually a pretty compelling deal.

What Most People Get Wrong About Midtown Office Space
The common narrative is that "offices are dead." That's a lazy take. Offices aren't dead; they’re just being sorted into winners and losers. 135 W 50th St NYC is currently in the "sorting hat" phase.
One thing people overlook is the sheer floor plate size. 135 W 50th St NYC has huge, open floors. In an era where companies want "collaborative spaces" (which is usually just a fancy way of saying they don't want to pay for cubicles), these big footprints are actually an asset. You can fit a lot of "collaboration" into 60,000 square feet of open floor.
The Tenant Mix: Who is Actually There?
It’s not just empty hallways. You’ve got companies like:
- Mazars USA: The accounting firm that famously handled some of Donald Trump's taxes (before they didn't).
- Urbanspace: They set up a food hall, which is a massive win for the building's street-level energy.
- George Comfort & Sons: Obviously, they keep their own headquarters there.
The presence of Urbanspace is actually a big deal. If you can get the public to walk into your building for a $18 ramen bowl, you’ve already won half the battle of making the space feel "alive." It creates a sense of "place" that 135 W 50th St NYC desperately needed.
The Future of 135 W 50th St NYC: Pivot or Perish?
What happens next? New York is currently obsessed with "office-to-residential" conversions. Everyone thinks every old office building should just be turned into apartments.
Here is the truth: 135 W 50th St NYC is a terrible candidate for that.
The floor plates are too deep. If you turned it into apartments, the people in the middle of the floor would never see the sun. They’d be living in windowless caves. Unless the city changes the building codes in a massive, sweeping way, this building is staying an office.

That means the owners have to keep doubling down on the "work-play" experience. They have to convince the next generation of CEOs that 135 W 50th St NYC is the sweet spot between "too expensive" and "too crappy."
Actionable Insights for Businesses and Observers
If you’re looking at space at 135 W 50th St NYC, or just trying to understand the NYC market, keep these things in mind.
First, leverage is everything. Buildings in special servicing or with high vacancy rates are desperate for stable, long-term tenants. You can negotiate for massive "tenant improvement" (TI) allowances. That means the landlord pays to build out your office. In 135 W 50th St NYC, you can get a space that looks like a Silicon Valley dream on a Midtown budget.
Second, look at the amenities, but check the "utilization." Don't just be impressed by the gym; ask how many people actually use it. A building that feels like a ghost town—even a fancy one—is bad for company culture.
Finally, watch the retail. The health of a building like 135 W 50th St NYC is often visible from the sidewalk. If the ground floor is vibrant and the food hall is packed, the office floors above usually follow suit.
The story of 135 W 50th St NYC isn't over. It’s just in a very loud, very expensive middle chapter. Whether it becomes a symbol of Midtown’s resilience or a cautionary tale of over-leverage remains to be seen. But for now, it’s a fascinating place to watch the future of work play out in real-time.
Next Steps for Moving Forward
If you are a business owner considering a move to Midtown, start by requesting a "stacking plan" for 135 W 50th St NYC to see exactly where the vacancies are. Large contiguous blocks of space are rare and give you the most power in lease negotiations. Additionally, tour the "Club 135" amenities during peak lunch hours. This will give you a raw, unfiltered look at the building's energy and whether it actually draws people out of their homes and into the office. Finally, consult with a tenant-rep broker who specializes specifically in Midtown West; the nuances of "Class A-" buildings are shifting weekly, and having someone who knows the current status of the building's debt will protect you from signing a lease in a property that might change hands mid-term.
