You’ve probably seen it while stuck in traffic on the Kennedy or walking to catch a Metra at Ogilvie. That sharp, glass-and-granite tower with the weird turret on the corner. Most people still call it the Heller International Building, even though that name has been technically obsolete for years. Nowadays, it’s officially 500 West Monroe.
Honestly, Chicagoans are stubborn about names. We still say "Sears Tower." We still say "Heller."
It stands 600 feet over the West Loop, a 45-story slab of Postmodernism that defined the city’s westward expansion in the early 1990s. But behind the fancy white lights that glow at the top every night, there is a messy, fascinating story of corporate musical chairs and a massive 2025 financial drama that currently has the building's future hanging by a thread.
The Architecture of a West Loop Giant
When Skidmore, Owings & Merrill (SOM) designed this thing back in 1992, they weren't just building an office. They were planting a flag. At the time, it was the tallest building west of the Chicago River. It held that title for a long time—25 years, actually—until River Point finally topped it out in 2017.
Architect James DeStefano, who was a big deal at SOM before starting his own firm, leaned heavily into the Postmodern vibe. You can see it in the way the building doesn't just "end." Instead, it has that distinctive southeastern corner turret. That turret isn't just for show; it’s the highest architectural point of the structure. It’s illuminated at night, looking a bit like a futuristic lighthouse for people commuting from the suburbs.
The materials are classic Chicago: granite, glass, and stainless steel.
The lobby is where things get weirdly fancy. They recently did a massive renovation to move away from that "stuffy 90s bank" feel. We're talking curved glass, "Golden Hour" inspired lighting, and even a massive imported rug that required overseas coordination just to fit through the door. Wright Heerema Architects handled the redesign, trying to make the space feel less like a transit hub and more like a hotel.
The $270 Million Mortgage Mess
If you want to understand the Heller International Building today, you have to look at the money. It's getting ugly.
In late 2025, news broke that JPMorgan Chase put a $270 million non-performing loan tied to the building up for sale. Basically, the owners—Spear Street Capital—defaulted. They bought the tower for around $412 million in 2019, right before the world changed. Then the loan matured in January 2025, and they couldn't pay the bill.
Why? Because the tenant list is shrinking.
- Motorola Solutions moved their HQ here a few years back but then started subleasing floors.
- Antares Capital packed up and headed to the BMO Tower.
- GE Healthcare and GE Transportation have both had a massive presence here, but the "office apocalypse" has hit the West Loop hard.
When you have a building that's nearly a million square feet and the big anchors start shedding space, the math stops working. Right now, the building is essentially in a state of financial limbo. A new buyer will likely take the title through a "deed-in-lieu of foreclosure," which is just a fancy way of saying they'll hand over the keys to avoid a legal fight.
What It’s Actually Like Inside
For the people who actually work there, the drama doesn't matter as much as the parking.
The building has 11 stories of parking. That is an insane amount for downtown Chicago. There are 1,300 spots. If you’ve ever tried to park near Union Station, you know that’s basically gold.
The floor plates are also kind of a marvel for their time. They are virtually column-free. Because SOM used a central core design, you get these wide-open spans of 28,500 square feet. If you’re a mid-sized company, you can own an entire floor without feeling like you're working in a maze of concrete pillars.
The Sustainability Irony
It’s funny that a building with a massive 11-story parking garage is also a "green" leader. But it is. 500 West Monroe has been LEED Gold certified for over a decade. They’ve won Energy Star awards every year since 2008. They use a fully integrated computer system to manage HVAC, which is why you don’t see people in those offices huddled under space heaters as much as they do in the older Loop buildings.
Why the Heller Name Sticks
Heller Financial was a powerhouse. When the building opened, they were the "it" firm. But then GE Capital bought them out in 2001 for about $9.6 billion.

Even though the Heller name came off the sign, it stayed in the maps and the minds of locals. It’s a landmark of the "New West Loop," the era before Fulton Market became a playground for Google and McDonald's. It represents a specific moment in Chicago history where the city decided it was okay to cross the river and build big.
Actionable Insights for the Future
If you are a business owner looking at space in the Heller International Building (500 West Monroe), or if you’re just a fan of the skyline, here is the ground truth:
- Watch the Sale: The $270 million loan sale is a signal. Expect a new owner by mid-2026. This usually means even more renovations or aggressive rent deals to fill the empty Motorola and Antares floors.
- Sublease Opportunities: Because of the current occupancy "mess," there are massive blocks of fully furnished, "plug-and-play" space available. If you need a full floor with 130+ workstations already wired, you can get it here for a fraction of what the new-build towers are charging.
- Transit is the Winner: Regardless of who owns it, the location is unbeatable for commuters. Being one block from both Ogilvie and Union Station is the building’s "moat." It will never stay empty for long because of those stations.
The Heller International Building isn't going anywhere, even if the bank currently holds the note. It’s too big to fail in the literal sense, and its 600-foot turret remains a permanent fixture of the Chicago night. Just don't be surprised if the name on the door changes again soon.
Keep an eye on the Crain's Chicago Business reports through the rest of the year. The transition of 500 West Monroe will be the bellwether for whether the West Loop office market is actually recovering or just stalling.
Next Steps for Research:
- Check the current "Sublease" listings: Sites like LoopNet or CBRE's local Chicago portal often list the specific floor plans for the vacant Motorola and Antares spaces.
- Visit the Lobby: If you're in the neighborhood, the lobby is public. You can see the Wright Heerema redesign firsthand to see how 90s architecture is being "modernized" for the 2020s.
