If you’ve ever walked the High Line in West Chelsea, you’ve definitely stared at it. You might not have known the address was 555 W 18th St New York, but the building—the IAC Building—is impossible to ignore. It looks like a giant, white glass sailboat frozen in mid-toss on the Hudson River.
Frank Gehry designed it. It was his first major project in New York City, and honestly, it changed the way people thought about office space in Manhattan. Before this, Chelsea was mostly gritty warehouses and industrial skeletons. Then Barry Diller’s IAC/InterActiveCorp planted this $100 million flag in the ground.
The Architecture of 555 W 18th St New York
Most people see the building and think it's just a weird shape for the sake of being weird. It isn't. The design actually mimics the "sails" of a ship. It's composed of two main levels: a five-story base that looks like it's swelling out, and a slimmer tower on top.
The glass is fascinating. It’s "fritted" glass. That basically means it has a ceramic pattern baked into it to reduce glare and heat. From a distance, it looks like solid white marble or maybe a thick fog, but when you get close, you realize it’s incredibly translucent.

Gehry used a "curtain wall" system. Each pane of glass is unique. Imagine trying to fit a jigsaw puzzle where every piece is curved in a different direction. It was a nightmare to build, but the result is a structure that looks like it's breathing.
Why the Location Matters
Chelsea is different now. In 2007, when the building opened, the High Line wasn't even finished yet. Back then, 555 W 18th St New York felt like an outpost. Today, it’s the centerpiece of a neighborhood that hosts Google, Chelsea Market, and some of the most expensive condos in the world.
- The High Line Connection: The park literally wraps around the neighborhood, giving tourists a bird's eye view of the building's lower tiers.
- The Art District: You’re steps away from the Gagosian and David Zwirner galleries.
- The Waterfront: Being right across from Chelsea Piers means the light hitting the building during sunset is legitimately world-class.
Inside the Sails
You can’t just walk in. It’s a corporate headquarters, not a museum. But if you’ve seen photos of the lobby, you know it features one of the world's largest high-resolution video walls. It’s over 120 feet long.

The interior layout is surprisingly open. Gehry didn't want a bunch of cubicles. He wanted a space that felt fluid, matching the exterior. The offices for brands like Match Group, Angi, and Dotdash Meredith have occupied this space over the years. It’s a hub of digital media and tech.
Fact-Checking the Rumors
People often get confused about who actually owns the land or if the building is sinking because it's so close to the river. It’s not sinking. The foundation is incredibly deep and reinforced.
Another misconception is that it’s a residential building. While Chelsea is full of luxury apartments like the nearby Lantern House (with those famous "bubble" windows), 555 W 18th St New York is strictly commercial. You can't live there, though plenty of tech executives probably spend enough time there to make it feel like home.

The Competition for Attention
Since its completion, the neighborhood has seen a massive influx of "starchitecture." Jean Nouvel’s 100 Eleventh Avenue is right next door with its mosaic of different-sized windows. Zaha Hadid’s 520 West 28th Street is a few blocks north.
Even with all these newer, shinier neighbors, the IAC Building holds its own. It has a softness that the glass-and-steel boxes of Hudson Yards lack. It feels human.
Practical Insights for Visiting
If you want the best view of 555 W 18th St New York, don't just stand on the sidewalk. Go up to the High Line at 18th Street.
- Golden Hour: The white glass catches the orange and pink hues of the sunset, making it look almost translucent.
- Photography: Use a wide-angle lens. The building is deceptive; it’s much wider than it looks from the street level.
- Night View: The internal lights make the "sails" glow from within. It’s one of the best-lit buildings in the city.
Moving Forward in West Chelsea
If you're looking into this area for business or just a weekend walk, keep in mind that construction never stops here. The corridor between 14th and 23rd streets is constantly evolving.
- Check out the Little Island park at Pier 55 while you’re there; it’s a short walk south.
- Visit the Whitney Museum further down for a broader perspective on how architecture and art intersect in this district.
- Keep an eye on the Chelsea Piers redevelopment plans, which will likely change the waterfront view again in the coming years.
The building at 555 West 18th remains a testament to a specific moment in NYC history when the city decided to stop being boring and start being experimental again. It's a landmark that isn't officially a "landmark" yet, but it might as well be.
