Midtown Manhattan is weird right now. Walk down 50th Street and you'll see exactly what I mean. Some buildings look like relics of a 1960s corporate fever dream that nobody woke up from, while others are desperately trying to figure out what they want to be when they grow up. Then there is 135 West 50th Street NYC. It sits there, a massive 23-story slab of glass and steel, acting as a sort of laboratory for the future of the American office. If you think this is just another boring skyscraper where people go to push paper, you haven't been paying attention to the real estate headlines lately.
The building is huge. We’re talking about 925,000 square feet of space. For decades, it was known as the Sports Illustrated Building. That name carried a certain weight, a mid-century prestige that felt permanent. But names change. Owners change. And honestly, the way we use buildings in New York has changed more in the last five years than in the previous fifty.
The Massive Identity Crisis of 135 West 50th Street NYC
Owned by UBS Realty Investors, this property has been through the ringer. It’s not just a place for desks; it’s a bellwether for the "flight to quality" trend everyone in real estate keeps screaming about. Here’s the thing: nobody wants to work in a dark, dingy cubicle farm anymore. If an employer wants people to actually show up in person, the building has to offer something better than a couch and a laptop at home.
UBS saw the writing on the wall. They poured tens of millions of dollars into a renovation that was basically a high-stakes bet on the survival of Midtown. They brought in the architects at Gensler—who are everywhere in NYC—to rethink the entire ground-floor experience. They didn't just polish the floors. They ripped the soul of the building open to create a through-block connection between 50th and 51st Streets. It’s a move that makes the building feel less like a fortress and more like a part of the city grid.
The Amenity War is Real
You've probably heard of "Club 135." If you haven't, it’s basically a 20,000-square-foot playground for adults who happen to be wearing business casual. It’s located on the second floor. It has a wellness center, lounge areas, and even a terrace. Yes, a terrace in the middle of Midtown. That’s like finding a diamond in a coal mine.
I was looking at the specs recently. The building features an 8,000-square-foot landscaped roof deck. In a city where outdoor space is the ultimate luxury, having a place to eat your overpriced salad while looking at the Radio City Music Hall sign is a major selling point. The developers realized that if they didn't provide "hospitality-grade" amenities, the building would just stay empty. It’s a harsh reality. Many older buildings in the neighborhood are struggling with high vacancy rates, but 135 West 50th has managed to snag some pretty big names.
Who is Actually Leasing Here?
It’s a mix. You have tech, finance, and traditional corporate tenants. Mizuho Americas is a massive presence there. They took a huge chunk of space—hundreds of thousands of square feet—which was a massive vote of confidence for the building’s redevelopment.

Then there’s the flexible workspace angle. Industrious, the co-working giant, operates a significant portion of the building. This is a smart move by the landlords. By having a mix of long-term corporate leases and flexible memberships, they’ve insulated themselves against the volatility of the market. If a startup needs ten desks for six months, they go to Industrious. If a global bank needs four floors for a decade, they sign with UBS.
- Mizuho Americas: The anchor that keeps the lights on.
- Industrious: The "cool" factor that brings in the freelancers and satellite teams.
- Volta Charging: Even the EV infrastructure people have a footprint here.
The retail situation is also worth noting. It’s not just empty storefronts. They’ve curated it to feel like a destination. You have the usual suspects, but the focus is on high-traffic, high-utility options that serve the people working upstairs.
Why the Location is Both a Blessing and a Curse
Let's be real: 50th Street can be a nightmare. You’re right in the thick of it. Rockefeller Center is a stone's throw away. The subway access is incredible—you’ve got the B, D, F, M at 47-50th Sts-Rockefeller Center and the 1 at 50th St. You can get anywhere.
But you also have to deal with the tourists. Thousands of them. Moving like slow-motion zombies toward the Christmas tree or the Nintendo Store. For a New Yorker trying to get to a 9:00 AM meeting at 135 West 50th Street NYC, navigating that sidewalk is a sport.
Yet, that density is exactly why the building stays relevant. It’s central. It’s the "Center of the Universe" vibe that global companies still crave. You aren't tucked away in some quiet corner of Chelsea. You are in the engine room of the city.
The Sustainability Question
We can't talk about NYC real estate without mentioning Local Law 97. If you aren't familiar, it’s the city’s aggressive plan to cut carbon emissions from buildings. Older skyscrapers are terrified of this because the fines for being "dirty" are astronomical.
135 West 50th has been making moves to stay ahead of the curve. The renovations included significant upgrades to the HVAC systems and energy efficiency. It’s currently LEED Silver certified. Is that the highest rating possible? No. But for a building of its age and scale, it’s a solid achievement that keeps the auditors happy and the energy bills (slightly) lower.
The Rent: What Does it Cost to Be Here?
Expensive. Obviously.
While prices fluctuate wildly based on the floor and the length of the lease, you’re looking at Class A pricing. In this part of Midtown, asking rents can easily range from $70 to $90 per square foot, and sometimes higher for the top-tier spaces with the best views.
Is it worth it?
If you’re a company that needs to impress clients and recruit talent who expects a gym and a rooftop bar in their office building, then yes. If you’re a scrappy five-person team, you’re probably better off in a converted warehouse in Long Island City. 135 West 50th is a "prestige" address. It’s for companies that have arrived.
The Architecture: A Mid-Century Modern Evolution
The building was originally designed by Emery Roth & Sons. If you know NYC architecture, that name is everywhere. They were the kings of the "wedding cake" and later the "glass box" styles. Completed in 1963, 135 West 50th was part of that post-war boom that defined the modern Manhattan skyline.
The recent lobby renovation by Gensler is a fascinating contrast. They took the rigid, somewhat cold aesthetic of the 60s and softened it. They added warmth, better lighting, and that "porous" feeling I mentioned earlier. It’s a lesson in how to respect the bones of a building while making it livable for 21st-century humans who have shorter attention spans and higher expectations for aesthetics.
What Most People Get Wrong About This Building
People think because it’s in Midtown, it’s stagnant. They assume these big towers are just waiting to be converted into condos. While office-to-residential conversion is a huge topic in NYC right now (just look at what’s happening at 25 Water Street), 135 West 50th is doubling down on the office.
The owners clearly believe that the office isn't dead; it’s just changing. They aren't trying to sell you a bedroom; they are selling you a "collaboration hub." It sounds like corporate jargon, and maybe it is, but the investment numbers don't lie. When a firm like Mizuho commits to massive square footage, they aren't doing it for the nostalgia of the Sports Illustrated days. They’re doing it because the building works.

Actionable Insights for Tenants and Visitors
If you're looking at space here or just visiting for a meeting, keep a few things in mind. The security is tight, as you'd expect for a building housing major financial institutions, so don't show up two minutes before your meeting and expect to sail through.
- Utilize the Through-Block Connection: If you’re coming from the north, use the 51st Street entrance. It’s often less congested than the main 50th Street side, especially during tourist peaks.
- Check Out the Retail: Don't just rush out for lunch. Some of the newer food and beverage options inside the building are actually better than the generic delis on the surrounding corners.
- The "Club" Access: If you're a tenant, maximize that second-floor amenity space. The terrace is one of the few places in Midtown where you can actually hear yourself think for a second.
- Transit Planning: Use the Rockefeller Center subway exits strategically. There’s an underground concourse system that can protect you from the rain or snow for several blocks if you know which stairs to take.
135 West 50th Street NYC is more than just a coordinate on a map. It’s a 925,000-square-foot testament to the fact that Manhattan always finds a way to iterate. It’s not the building it was in 1963, and it won't be the same building in 2043. But for now, it’s one of the best examples of how to keep a giant relevant in a world that’s constantly trying to go remote.
If you want to understand the future of the New York office market, stop looking at the new glass needles at Hudson Yards for a second and look at how the old guards like 135 West 50th are fighting back. They are winning by becoming more human, more open, and a lot more expensive. It’s the New York way.
