Walk past the corner of 10th Avenue and 33rd Street today and you’ll see a shimmering, pleated glass giant that looks like it belongs in a sci-fi reboot of Manhattan. It’s sleek. It’s expensive. It’s very "New Hudson Yards." But if you’ve lived in New York long enough, you remember what 450 West 33rd Street used to look like. It was a beige, concrete fortress. A windowless, hulking mass of Brutalism that people affectionately—or maybe out of spite—called the "Lego building" or the "Ikea box."
It was ugly. Really ugly.
But honestly, that ugliness is exactly why it’s now one of the most successful commercial real estate transformations in the history of the city. We’re talking about 2.1 million square feet of space that went from housing printing presses and mail sorters to hosting the high-tech engine rooms of Amazon and JPMorgan Chase. Now known as 5 Manhattan West, this building didn't just get a facelift; it underwent a total DNA transplant.
The Brutalist Bones of 450 West 33rd Street
Davis Brody Bond designed the original structure in 1969. Back then, the West Side was a gritty wasteland of rail yards and industrial warehouses. They weren't trying to make something pretty. They were building a "Superblock." The original 450 West 33rd Street was a massive pyramidal structure with sloped walls, designed specifically to hold the weight of heavy machinery.
It was a machine for working.
Because it was built over the Penn Station rail ditch, the engineering was—and still is—insane. The building sits on massive steel stilts. You can’t just dig a basement when there are active Amtrak and LIRR trains screaming underneath your feet. This structural necessity gave the building something rare in Manhattan: massive floor plates. We’re talking over 100,000 square feet on a single level.
That’s basically unheard of in Midtown. Most older skyscrapers are like wedding cakes—they get skinnier as they go up. But 450 West 33rd Street stayed fat. In the 70s and 80s, this was perfect for the New York Daily News and the Associated Press. They needed room for giant rolls of newsprint and frantic newsrooms. But as the world went digital, those massive, dark, concrete floors became a liability. The building was a relic. It was a giant tomb of 20th-century industry in a 21st-century city.
The Rex Transformation: Peeling the Concrete
When Brookfield Properties took over the site as part of their massive $5 billion Manhattan West development, they had a choice. They could tear it down, or they could try something crazy. They chose crazy. They hired REX, the architecture firm led by Joshua Ramus, to "re-skin" the building.

They didn't just paint the concrete. They literally chopped it off.
Engineers used specialized rigs to slice away the heavy precast concrete slabs that gave the building its sloped, "Ziggurat" shape. It was a surgical operation on a gargantuan scale. Once the concrete was gone, they replaced it with a pleated, high-performance glass curtain wall.
The result?
The pleats aren't just for looks. By tilting the glass, the architects managed to create self-shading sections that reduce solar heat gain while still letting in a ridiculous amount of natural light. Suddenly, the building that felt like a bunker was glowing. It went from being the neighborhood eyesore to being the "cool older brother" of the shiny new towers at Hudson Yards.
Why Tech Giants Fell in Love with a 1960s Warehouse
You might wonder why Amazon didn’t just move into a brand-new skyscraper next door. It’s about the vibe. Tech companies and modern creative agencies have a weird obsession with industrial history. They want the high ceilings and the "ruggedness" of an old warehouse, but they also want the floor-to-ceiling glass and the lightning-fast fiber of a New Build.
450 West 33rd Street offered both.
Amazon took over 360,000 square feet here. Why? Because they could fit thousands of engineers on just a couple of floors. It fosters a weird kind of collaborative energy you just don't get when your team is spread across ten different levels of a skinny tower. JPMorgan Chase’s "FinTech" wing did the same thing. They wanted to feel like a startup, even if they had trillions in assets.

There’s also the ceiling height. Most modern office buildings give you maybe 9 or 10 feet of clearance. Because 450 West 33rd Street was built for heavy printing presses, the ceilings are massive—some over 14 feet. It feels airy. It feels like you can actually breathe, which is a luxury in a city where most offices feel like cubicle coffins.
The Reality of the Neighborhood Shift
It’s easy to get swept up in the architectural praise, but we should be real about what this meant for the neighborhood. Before the transformation of 450 West 33rd Street, this part of town was a "No Man’s Land." You went there to catch a bus or maybe buy a cheap hot dog. Now, it’s a high-end campus.
The building is the anchor of the Manhattan West plaza, a two-acre public space that connects the building to its neighbors: One, Two, and Five Manhattan West. You’ve got high-end eateries like Ci Siamo and the massive Whole Foods right at the base. It’s a total ecosystem.
But it’s also a symbol of how Manhattan is becoming a playground for the ultra-wealthy and the corporate elite. The "gritty" West Side is gone. In its place is a highly curated, glass-and-steel version of New York that feels a bit like a luxury mall. Is that better? For the city's tax base, absolutely. For the soul of the old Garment District? That’s up for debate.
The Engineering Nerd Stuff (That Actually Matters)
If you’re into the technical side, the way they handled the "over-build" is fascinating. Remember those trains I mentioned? Because the building sits over the Northeast Corridor tracks, the weight distribution has to be perfect. When REX removed the concrete and added the glass, they actually lightened the load on the 1960s steel structure.
This gave them "weight credit."
They used that credit to create massive outdoor terraces. In a post-pandemic world, outdoor space is the ultimate flex for an office building. At 450 West 33rd Street, they carved out 1,600 square feet of terrace space on the upper floors. It’s not just a balcony; it’s a park in the sky overlooking the High Line.

What People Often Get Wrong About 5 Manhattan West
A lot of people think 5 Manhattan West is a brand-new building. I’ve heard tourists standing on 10th Avenue saying, "Look at that new modern tower!"
It’s not new. It’s a 50-year-old skeleton in a $200 million suit.
Another misconception is that it's just another office building. It's actually a massive mixed-use hub. The Peloton Studios are there. You can literally walk into the building, take a world-class spin class, grab a $15 salad, and then walk past the elevators where some of the most powerful people in finance are heading to work.
The building is also a case study in sustainability through "adaptive reuse." Tearing down a building the size of 450 West 33rd Street would have created a staggering amount of carbon waste. By keeping the steel and the "bones," the developers saved a fortune and kept thousands of tons of debris out of landfills. It’s arguably the "greenest" way to build a skyscraper: don't build a new one.
Actionable Insights for Visiting or Leasing
If you're looking at 450 West 33rd Street from a business or even a tourist perspective, there are a few things you should know to navigate the space effectively.
- The Best View: Don't just look at it from 10th Avenue. Go to the High Line at 30th Street. The way the "pleated" glass reflects the sunset is one of the best photo ops in the city.
- The Food Situation: The "Manhattan West" plaza is actually better for food than the main Hudson Yards mall. It’s less crowded and has more "chef-driven" options.
- Transit Access: While it's near the 7-train at Hudson Yards, the "secret" move is using the West Side entrance of Penn Station. You can be off an LIRR train and inside the lobby of 450 West 33rd Street in under five minutes without ever really going "outside" into the elements.
- For Commercial Tenants: If you’re looking for space here, know that the "low-rise" floors are actually some of the most desirable because of the massive floor plates. Higher isn't always better in a building this wide.
This building is a survivor. It survived the decline of the newspaper industry, the collapse of the old West Side, and the total redesign of its own face. It’s a reminder that in New York, you don't always have to start over to become something completely new. You just need a really good architect and a lot of glass.
