You’ve seen it on postcards. You’ve seen it in the background of every Spider-Man movie ever made. 175 5th Ave New York NY is better known as the Flatiron Building, and honestly, it’s a miracle the thing is even standing when you look at the footprint it occupies. It sits there like a massive limestone ship sailing up Broadway, stubbornly refusing to move for the grid system that defines the rest of Manhattan.
It’s weird. It’s iconic. It’s also currently a bit of a mess behind the scenes.
If you walk past the intersection of 23rd Street, Fifth Avenue, and Broadway today, you’ll see it. But you might see it covered in scaffolding. People come from all over the world just to snap a photo of that narrow "point," which is only about 6.5 feet wide. Imagine trying to fit a desk in that corner. You can’t.
The Renaissance of 175 5th Ave New York NY
The building wasn't always a beloved landmark. When it was completed in 1902, critics hated it. They called it "Burnham’s Folly" after the architect Daniel Burnham. People were legitimately convinced that the wind currents created by its triangular shape would literally knock the building over. They waited for it to collapse. It didn't. Instead, it became the anchor of the Ladies' Mile Historic District.
The structure is a steel-frame pioneer. Before this, buildings needed thick masonry walls to stay up. Because 175 5th Ave New York NY used a steel skeleton, it could soar to 22 stories without the base being twenty feet thick. It was one of the first "skyscrapers" to actually look like one, wrapped in beautiful terra cotta and limestone designed in the Beaux-Arts style.
What’s happening inside right now?
It’s empty.
That’s the part that catches people off guard. For decades, it was the home of St. Martin’s Press and Macmillan Publishers. But in 2019, the last of the office tenants packed up. Since then, the building has been a bit of a ghost ship. There was a massive legal battle between the owners—GFP Real Estate, Sorgente Group, and ABS Real Estate—and a minority owner named Nathan Silverstein. It got ugly. It got "court-ordered auction" ugly.
In a bizarre turn of events in 2023, the building went up for auction on the steps of a courthouse. A guy named Jacob Garlick bid $190 million, won, and then... didn't pay the deposit. It was a total circus. Eventually, the original majority owners bought it back for $161 million.

Residential is the New Office
The future of 175 5th Ave New York NY isn't cubicles and water coolers. It’s luxury living.
The owners have officially filed plans to convert the upper floors into roughly 40 to 60 high-end condominiums. It makes sense. Trying to modernize a 120-year-old triangular building for tech-firm office standards is a nightmare. The elevators are old (and famously slow), the floor plates are awkward, and the plumbing is a constant battle. But for a billionaire who wants to live in the "nose" of the most famous triangle in the world? That’s a selling point.
Converting a landmark like this is basically a surgical procedure. You can't just tear down walls. The Landmarks Preservation Commission watches every single nail. They have to keep the historic character while somehow making it livable for 2026 standards.
The ground floor will likely remain retail. It’s too valuable not to. But the days of wandering into the lobby to find a publishing house are over.
The "23 Skidoo" Myth
You’ve probably heard the phrase "23 Skidoo." Local lore says it originated right here at 175 5th Ave New York NY. Because of the building's shape, the wind would whip around the point and lift up women’s skirts. Men would hang out on 23rd Street to catch a glimpse, and the police would tell them to "23 Skidoo"—basically, "get lost."
Is it 100% historically verified? Most etymologists say it's a bit of a stretch. But in New York, the legend usually matters more than the data. It’s part of the building's DNA.
Why the Architecture Still Confuses People
The Flatiron isn't actually a triangle. Not a perfect one, anyway. It’s a right-angled triangle, or close to it, following the diagonal cut of Broadway.

The design is split into three parts, like a Greek column:
- The Base: Sturdy, heavy stone that feels grounded.
- The Shaft: The long middle section with those repetitive, textured windows.
- The Capital: The ornate top where the cornices flare out.
Looking up at it from the Madison Square Park side, the building looks incredibly thin. It’s an optical illusion that makes it feel two-dimensional from certain angles. This is why it’s the most photographed building in the city, arguably more than the Empire State Building. You can’t get that perspective anywhere else.
The Problem with Windows
Modern offices love floor-to-ceiling glass. 175 5th Ave New York NY has the opposite. It has thousands of small, deep-set windows. For a resident, this is great—it feels private and historical. For a corporate law firm, it’s dark and cramped. This mismatch is exactly why the residential conversion is the only way the building survives the next century.
Real estate experts like Dan Kaplan at FXCollaborative have often pointed out that these "pre-war" gems are actually better suited for housing because they have "operable windows" (they actually open!) and smaller floor plates that allow light to reach the center of the unit.
