Walk down 56th Street and turn the corner onto Fifth Avenue, and you’re staring at a glass-and-marble giant that basically tells the story of Manhattan real estate in a single block. 717 5th Ave New York isn't just another office tower. It’s a 26-story puzzle. You’ve got the SL Green and Jeff Sutton history, the massive retail footprint that brands kill for, and a recent shift in ownership that signaled a massive change in how luxury giants view the dirt they stand on.
It’s the Glass Tower.
Some call it that because of its distinct aesthetic, but lately, the conversation around the building has shifted from its architecture to its balance sheet. In early 2024, the game changed. Gucci’s parent company, Kering, dropped $963 million to buy the retail portion of the building. Think about that for a second. Nearly a billion dollars for the bottom floors. That isn't just a real estate play; it's a defensive maneuver in a world where luxury brands are tired of paying astronomical New York rents to third-party landlords.
The Massive Shift at 717 5th Ave New York
For decades, the standard play was simple: a developer owns the building, and the brand signs a long-term lease. But 717 5th Ave New York became the poster child for the "buy-your-own-flagship" movement. Kering followed the lead of Prada, which had just snagged its own spot nearby. When you look at the 115,000 square feet of multi-level retail space at the base of 717 Fifth, you see why. It’s prime. It’s legendary. It’s where the world’s wealthiest tourists go to spend money they haven't even made yet.
The tower portion remains a different beast entirely. While the retail is booming, the office space reflects the broader struggle of Midtown's older "Class A" stock. Built in 1958 and renovated multiple times, the building has had to work hard to keep up with the shiny new toys at Hudson Yards or the ultra-modern One Vanderbilt. Honestly, it’s a bit of a tug-of-war. On one hand, you have the prestige of the address. On the other, you have the reality of 1950s floor plates in a 2026 world.
Who Actually Runs the Show Here?
The ownership history of 717 5th Ave New York reads like a "who’s who" of New York power players. You had the Blackstone Group involved at one point. Then SL Green Realty Corp. and Jeff Sutton’s Wharton Properties took the reins. Sutton is a legend for a reason—he’s the guy who basically reshaped Fifth Avenue retail. But even giants pivot. By selling the retail condos to Kering, the sellers cashed in on the one thing that never seems to lose value: the literal ground floor of American consumerism.
The office component? That stayed with the joint venture for a while. It’s a mix of financial firms, private equity, and the kind of boutiques that want a Fifth Avenue business card but don’t need 50,000 square feet of open-plan tech space. The lobby is sleek, sure, but it’s the views of Central Park from the upper floors that keep the vacancy rates from plummeting. If you're on the 20th floor, you’re looking right at the greenery. It's hard to put a price on that, though the appraisers certainly try.

Why This Specific Building Matters for the Future of Manhattan
Most people think of 717 5th Ave New York as just another skyscraper. They're wrong. It’s a barometer. When the Kering deal closed, it told every analyst on Wall Street that the "Retail Apocalypse" didn't apply to the top 0.1%. While malls in the Midwest were being turned into pickleball courts, Fifth Avenue was being bought up by the very brands that sell $4,000 handbags.
It also highlights a weird fragmentation in the market.
Luxury is doing great.
Mid-tier retail? Not so much.
High-end office? Selective.
The building sits at the epicenter of this. You have the Hugo Boss flagship there, which has been a staple for years. The way these stores are designed now isn't just about shelves; they’re "brand cathedrals." They have to be big. They have to be imposing. 717 5th Ave New York provides that scale. The 26 stories above it are almost like a crown for the retail activity happening on the sidewalk.
Modernizing a 1950s Icon
Let's talk about the bones of the place. 717 Fifth was designed by Harrison & Abramovitz. These guys weren't amateurs; they worked on the UN Headquarters and Lincoln Center. The building was originally the Corning Glass Building, which explains the "Glass Tower" nickname. But 1958 glass isn't 2026 glass. The building has undergone massive mechanical upgrades to stay LEED certified and attract tenants who care about ESG (Environmental, Social, and Governance) scores.
If you're a tenant here, you're looking at:
- High-efficiency HVAC systems that don't sound like a jet engine.
- A lobby that feels more like a hotel than a DMV.
- Security protocols that are, frankly, a bit intense but necessary given the high-profile retail below.
Interestingly, the building has a bit of a split personality. The Fifth Avenue entrance is all about that retail glitz. But the office entrance on 56th Street is quieter, more understated. It’s a classic New York "Billionaire’s Row" vibe—expensive but not shouting about it.

The Numbers You Should Actually Care About
When Kering bought the retail, the price worked out to some astronomical numbers per square foot. While office space in the area might trade for $1,000 to $2,000 a foot, the retail portion of 717 5th Ave New York essentially broke the scale. It reflects a trend where the "dirt" value of Fifth Avenue is decoupling from the "office" value of the air above it.
Basically, the dirt is gold. The air is... well, it’s just expensive real estate.
One of the nuances people miss is the "corner" factor. 717 5th Ave New York occupies the southeast corner of 56th and 5th. In retail, corners are everything. You get double the window display. You get double the foot traffic. You get the visibility that a mid-block building simply can't compete with. That’s why the vacancy in the retail portion of this building is almost always zero, even when the rest of the city is struggling.
What’s Next for the Tower?
There is constant chatter about whether the upper floors of 717 5th Ave New York could ever go residential. It’s a trend we’re seeing across Midtown—zombie office towers being converted into luxury condos. But 717 is in a weird spot. The floor plates are actually pretty decent for offices, and the location is still too "corporate" for some residents who prefer the quiet of Park Avenue.
For now, it remains a hybrid. A retail powerhouse on the bottom, a steady office performer on top.
If you're looking at the building from an investment or business perspective, the takeaway is clear: 717 5th Ave New York is no longer a speculative asset. It’s a foundational asset. When a company like Kering moves in with a billion-dollar check, they aren't planning to leave in ten years. They’re planning to be there for fifty. This stabilizes the entire block. It keeps the neighboring buildings like Trump Tower and the Tiffany & Co. flagship relevant.

Practical Insights for Navigating the 717 Area
If you're heading to 717 5th Ave New York for a meeting or just to shop at the flagships, here’s the reality of the situation.
First, don't even think about driving. The traffic on 5th is a nightmare, especially with the security perimeters often set up near the nearby high-profile towers. Take the E or M train to 5th Ave/53rd St and walk the few blocks. It’s faster.
Second, if you're a business looking for space, understand that 717 is a prestige play. You’re paying for the address. If you need 100,000 square feet of "cool" tech space with exposed brick, this isn't it. This is where you go when you want your clients to know you've "arrived."
Third, keep an eye on the retail transitions. With Kering in control, expect the 717 5th Ave New York storefronts to become even more experimental. We’re talking about "phygital" retail—high-tech displays mixed with old-school luxury service.
Next Steps for Stakeholders and Visitors:
- For Investors: Watch the nearby sales. The Prada and Kering acquisitions have set a new floor for Fifth Avenue pricing. Any "discounted" office stock in the vicinity is now a prime target for retail conversion.
- For Retailers: Study the 717 floor plans. The multi-level integration is a masterclass in how to draw customers from the street up to a second or third level, which is notoriously difficult in Manhattan.
- For Tourists: Visit the Hugo Boss flagship not just to shop, but to see the architecture of the "Glass Tower" from the inside. The way the light hits the corner of 56th and 5th through those floor-to-ceiling windows is genuinely one of the best views in Midtown.
The story of 717 5th Ave New York is still being written. It survived the 1970s fiscal crisis, the 2008 crash, and the 2020 pandemic. Every time, it comes out looking a little shinier—and costing a lot more. It’s a testament to the fact that in New York, the right corner is worth more than almost anything else.
