You’ve probably seen it if you’ve walked along the East River lately. 161 Maiden Lane New York—often marketed as "One Seaport"—was supposed to be this glittering, 60-story glass jewel in the Financial District crown. It was going to be the first all-glass residential tower in the area. Instead, it’s basically become a $500 million cautionary tale that’s currently leaning three inches to the north.
It's leaning. Seriously.
When people talk about New York real estate, they usually focus on record-breaking penthouses or shady offshore buyers. But 161 Maiden Lane is different because it’s a physical manifestation of what happens when ambitious engineering meets a legal and financial nightmare. It’s not just a building; it’s a decade-long saga of lawsuits, construction halts, and a literal tilt that has kept the site in a state of suspended animation while the rest of Lower Manhattan moves on.
The Leaning Tower of Seaport
So, how does a modern skyscraper in the middle of Manhattan end up leaning? It sounds like something out of the 19th century, not the 2020s. The issue at 161 Maiden Lane New York traces back to the foundation work. The developer, Fortis Property Group, and their contractors have been locked in a bitter dispute for years over who is actually responsible for the building’s slight, but very expensive, misalignment.
RC Andersen, the original concrete contractor, was blamed by Fortis for a botched "foundation pour." The theory was that the building settled unevenly into the soft soil near the river. RC Andersen hit back, claiming the issue was actually with the building's design and the way the developer managed the site. It’s a classic "he-said, she-said" but with hundreds of millions of dollars and a 670-foot tower on the line.
By 2018, the lean was undeniable. Pizzarotti, the construction firm initially hired to oversee the project, eventually sued Fortis, claiming the building was structurally unsound. They even alleged that the glass curtain wall—the very thing that was supposed to make the building iconic—couldn't be properly installed because the slabs were out of alignment. Fortis countered by saying the lean was minor and could be "engineered out" during the finishing phases. But if you’re a buyer looking at a $5 million condo, "kinda leaning but we can fix it" isn't exactly the pitch you want to hear.

A Ghost on the Skyline
Walking by the site today is eerie. You see a building that looks 90% finished. The glass is mostly up. From a distance, it looks like any other luxury tower. But look closer and you see the sidewalk sheds that have been there forever. You see the lack of activity. It’s a ghost.
Honestly, the tragedy here isn't just the engineering. It’s the timing. The project launched when the luxury condo market in NYC was screaming. It survived the initial "Billionaire's Row" boom, but by the time the legal battles reached a fever pitch, the market had shifted. Then COVID-19 hit. Then interest rates spiked.
What was once a premium asset became a liability that no one wanted to touch. Lenders like Bank Leumi, which provided the construction financing, eventually moved toward foreclosure. This is where the business side of 161 Maiden Lane New York gets really messy. When a project this big fails, it’s not just the developer who loses. It’s the lenders, the subcontractors who haven't been paid, and the city itself, which is left with a massive, unusable shell in a high-traffic zone.
Why the "Lean" Isn't the Only Problem
Most people fixate on the tilt because it’s a great headline. "The Leaning Tower of Seaport" writes itself. But the reality is that 161 Maiden Lane New York suffered from a cascade of failures.
- Safety Issues: The site was plagued by safety violations. In 2017, a construction worker tragically fell to his death from the 29th floor. This led to immediate halts and increased scrutiny from the Department of Buildings (DOB), which never really went away.
- The Glass Problem: Because the building is leaning, the custom glass panels—which were manufactured to incredibly tight tolerances—didn't fit the way they were supposed to. It’s like trying to put a square peg in a slightly slanted hole. You can't just "stretch" glass.
- Financing Deadlocks: Once the lawsuits started flying between Fortis and Pizzarotti, the money dried up. In NYC real estate, momentum is everything. Once you lose it, the carry costs (taxes, insurance, security) start eating the project alive.
The Legal Quagmire
The court records for this address are a mile long. You've got Pizzarotti suing Fortis. Fortis suing Pizzarotti. Bank Leumi suing to foreclose. Fortis trying to block the foreclosure. It’s a circular firing squad of litigation.

In late 2022 and throughout 2023, there were flashes of hope. There was talk of a settlement. There were rumors that a new contractor would come in, shim the floors, and finish the interior. But as of 2026, the building remains a shell. The legal system moves slowly, especially when you’re dealing with complex construction liability and hundreds of millions in debt.
The complexity comes down to the "cure." Fixing a leaning building isn't impossible—look at the Millennium Tower in San Francisco—but it is incredibly expensive. You have to essentially go back into the foundation, add piles, and use massive jacks to stabilize or redistribute the weight. For 161 Maiden Lane New York, the question has always been: Is the finished value of the condos worth the cost of the fix? In a high-interest-rate environment where luxury buyers have plenty of other (straighter) options, the math just doesn't seem to work.
What Happens Next?
If you're looking for a quick resolution, don't hold your breath. The site is currently tied up in the aftermath of a foreclosure sale. Often, in these situations, a new developer will eventually buy the debt at a massive discount, "wash" the project of its previous legal baggage, and spend the money to finish it.
But even then, the stigma is real. Would you buy a condo in a building known globally for having a foundation issue? Maybe at a 40% discount. But 161 Maiden Lane was designed for the 1%. Those buyers don't usually do "discounts" on structural integrity. They just go buy at 25 Park Row or the Seaport Residences instead.
Navigating the Seaport Real Estate Scene
If you're an investor or just someone curious about the neighborhood, there are a few things to keep in mind regarding this specific corner of Manhattan:

- Check the DOB Records: If you're ever looking at property in New York, the Department of Buildings (DOB) portal is your best friend. You can see every "Stop Work Order" ever issued for 161 Maiden Lane. It's a sobering read.
- Neighborhood Impact: Despite the failure of this one tower, the Seaport District is actually doing okay. The Tin Building by Jean-Georges and the revamped Pier 17 have brought a lot of life back to the area. 161 Maiden Lane is an outlier, not the rule.
- Foundation Matters: The soil in this part of Manhattan is basically landfill and silt. It’s not the solid bedrock you find further uptown. Any project here requires incredibly sophisticated foundation engineering. 161 Maiden Lane is a reminder that you can't cut corners on the "unseen" parts of a building.
Actionable Steps for Stakeholders and Observers
If you are a nearby resident or a real estate professional tracking 161 Maiden Lane New York, here is how you should approach the situation:
Monitor the Foreclosure Proceedings
The ownership of the building is the only thing that will trigger a restart. Keep an eye on New York County Supreme Court filings for any "Notice of Sale" or transfers of the deed. Until the title is clean, no construction crew is coming back.
Expect Continued Scaffolding
Don't expect the sidewalk sheds to disappear anytime soon. Even if the building is dormant, the city requires those sheds for public safety. If you’re a local business, plan for that visual obstruction to be part of the landscape for at least another two to three years.
Analyze the "Poured-in-Place" Data
For those in the AEC (Architecture, Engineering, Construction) industry, this building is a case study in why "design-build" contracts need ironclad liability clauses regarding site conditions. The shift toward more modular or pre-cast elements in NYC is partly a reaction to the risks highlighted by the 161 Maiden Lane fiasco.
Look for Rebranding
If this building ever does open, it won't be called "One Seaport" or "161 Maiden Lane." It will be rebranded with a completely new name to distance it from the "leaning" headlines. That’s the oldest trick in the NYC real estate book.
The story of 161 Maiden Lane New York isn't over, but it has certainly stalled. It serves as a stark reminder that in the world of vertical ambition, the most important thing isn't the glass on the outside, but the dirt and concrete underneath. Until someone decides it's worth the hundreds of millions to straighten things out, it will remain a very expensive, very shiny, and very crooked monument to the complexity of the New York skyline.
