If you’ve walked down Madison Avenue lately, specifically that high-octane stretch between 58th and 59th Streets, you’ve probably noticed something feels... off. Or maybe just quiet. For decades, 625 Madison Avenue New York was a titan of the Plaza District. It wasn't just another office block; it was the headquarters of Revlon, a symbol of mid-century corporate power, and a prime piece of the most expensive real estate puzzle in the world.
But things changed. Fast.
The building is currently at the center of a massive transformation that tells the story of how New York City is basically trying to reinvent itself after the world turned upside down in 2020. We aren't just talking about a fresh coat of paint. We are talking about a total identity crisis for a 17-story structure that occupies a full block front.
The Messy Reality of the SL Green Era
For a long time, the name most associated with this address was SL Green Realty Corp. They are the biggest office landlord in the city, so it made sense. They held the leasehold, which basically means they owned the building but not the dirt underneath it. That’s a common but incredibly risky way to do business in Manhattan.
The "dirt" belonged to the Ashkenazy Acquisition Corp.
Then came the rent reset. Honestly, this is where it gets technical but also kind of dramatic. In Manhattan ground leases, the rent the building owner pays the landowner usually gets "reset" every few decades based on the current value of the land. When 625 Madison Avenue New York hit its reset point, the numbers were astronomical. We’re talking about a jump from roughly $4.6 million a year to over $20 million.
SL Green saw the writing on the wall. They essentially handed the keys back through a foreclosure process. It was a massive move that signaled a shift in how developers view older, Class B office spaces. If the math doesn't work, even the biggest players in the game will walk away. It was a cold, calculated business decision that left a lot of people wondering: what do you actually do with a vacant 560,000-square-foot building in the middle of a luxury shopping district?
Why 625 Madison Avenue New York is Different from its Neighbors
You have the GM Building right there. You have the Apple Store’s glass cube just a stone's throw away. This neighborhood is the "Gold Coast" of retail.
Most of these buildings are aging, but 625 Madison is a bit of a weird bird. Built in 1956, it was designed by Sylvan Bien. It’s got that classic wedding-cake setback style that was popular after the 1916 zoning laws. While its neighbors like 432 Park Avenue are screaming toward the clouds with ultra-luxury condos, 625 stayed grounded as a functional, somewhat utilitarian office space.
- The Revlon Legacy: For years, Revlon’s presence gave the building a certain "Mad Men" era glamour. When they left, the soul of the building seemed to exit with them.
- Retail Power: Despite the office vacancies, the ground floor remains some of the most coveted real estate on the planet. Think Fratelli Rossetti and other high-end boutiques that define the Madison Avenue experience.
The building is currently in a state of flux. Related Companies, the giant behind Hudson Yards, eventually took control of the site after the SL Green exit. Stephen Ross and his team don't usually do "small" or "quiet." When Related gets involved, it usually means a wrecking ball or a multibillion-dollar transformation is on the horizon.
The Conversion Conversation: Office to Residential?
Everyone in New York is talking about office-to-residential conversions. It’s the buzzy solution to the housing crisis and the "death of the office" narrative. But is 625 Madison Avenue New York a candidate for this?
It's complicated.
Converting an office building isn't as simple as putting up some drywall and calling it an apartment. You have to deal with "deep floor plates." Offices are often huge squares where the middle of the floor has no windows. Nobody wants a bedroom with no light. However, the setbacks at 625 Madison actually make it a better candidate than most. Those terraces—the ones Revlon executives used to look out from—are gold mines for luxury condos.
The rumor mill in the real estate community, including whispers from insiders at firms like Cushman & Wakefield and JLL, suggests that a mixed-use future is almost certain. You'd have ultra-high-end retail at the base, maybe a few floors of "boutique" office space for hedge funds that want to be near Central Park, and the rest? Likely residences that will sell for tens of millions of dollars.
What Most People Get Wrong About the Value
People see a "vacant" building and think it’s a failure. That’s a mistake. In the world of Manhattan development, a vacant building is often more valuable than a full one.
Why? Because tenants have rights. If you want to tear a building down or do a massive $500 million renovation, you can't do it with a law firm on the 12th floor that has a lease until 2032. Vacancy equals opportunity. It means the developer has a clean slate.
Related Companies didn't buy into 625 Madison Avenue New York to be a landlord to mid-sized nonprofits. They bought the potential of the 0.88-acre lot. In a city where you can't manufacture more land, owning a full block front on Madison is like owning a rare Picasso. You don't care if the frame is dusty; you care about the canvas.
Looking at the Numbers (The Real Ones)
Back in the day, the building was valued somewhere north of $600 million. During the height of the ground lease dispute, those numbers fluctuated wildly. When Related took over the debt and eventually the deed, the transaction was viewed as one of the most significant "distressed" plays in recent years.
But "distressed" is a relative term.
The land itself is worth a fortune. The zoning allows for significant density. If the developers decide to utilize "air rights" from surrounding smaller buildings, they could theoretically build something much taller than the current 17 stories. This is the "Billionaires' Row" effect creeping north.
What This Means for the Neighborhood
Madison Avenue has been struggling a bit. It’s not a secret. Between the rise of SoHo as a luxury hub and the sheer convenience of the Meatpacking District, the Upper East Side's retail corridor had to fight back.
A revitalized 625 Madison Avenue New York is the linchpin. If Related builds a masterpiece here, it anchors the entire stretch. It brings back the foot traffic. It brings back the "it" factor.
Imagine a world-class hotel or a flagship store for a brand like Chanel or Hermès taking over the corner. It changes the gravity of the street. Right now, it’s a bit of a ghost, but the bones are there.
Navigating the Area Today
If you're visiting or working nearby, don't expect to see much action inside the lobby. It’s mostly staging for what's to come.

- Dining: You’re right by the Polo Bar. If you can get a reservation (good luck), it’s the place to see the people who are actually making the decisions about these buildings.

Actionable Insights for the Curious
If you are a real estate enthusiast, an investor, or just someone who loves the architecture of the city, here is how you should watch this space:
1. Watch the DOB Filings
The Department of Buildings (DOB) website is where the real news breaks. Look for "Full Demolition" permits or "Major Alteration" (Alt-1) filings for 625 Madison. That will tell you if they are keeping the shell or starting over.
2. Follow the Retail Leases
When a big-name luxury brand signs a long-term lease at the base of a "quiet" building, it’s a signal that the renovation plans are finalized. These brands don't move into construction zones without a guaranteed finish date.
3. The Residential Market Pulse
Keep an eye on the "absorption rate" of luxury condos in the 57th Street corridor. If the units at 432 Park and 111 West 57th continue to sell, expect 625 Madison to go full residential. If that market cools, we might see a more creative "hospitality-first" approach.

The story of 625 Madison Avenue New York isn't a tragedy of a vacant building. It’s a prologue. We are currently in that weird, quiet moment before the curtain goes up on the next act. Whatever happens next—whether it’s a glass tower or a restored limestone beauty—it’s going to redefine this corner of Manhattan for the next fifty years. Keep your eyes on the scaffolding.
