If you’ve spent any time in the Loop, you know the building. It’s that massive, glass-skinned spaceship that looks like it crash-landed right in the middle of Chicago’s grid. People call it the James R. Thompson Center, but most locals just know it by its address: 100 W Randolph Street Chicago IL 60601. For decades, it was the place you went to renew your driver’s license or wait in a soul-crushing line for state permits. It was loud. It was drafty. Honestly, it was a bit of a mess. But right now, this specific coordinate in the city is undergoing one of the most radical transformations in American real estate history. It isn't just a government office anymore. It’s becoming the future home of Google.
The building occupies an entire city block. That’s rare. You’ve got Randolph to the south, Lake to the north, LaSalle to the west, and Clark to the east. It is the literal heart of the city's legal and governmental district. When Helmut Jahn designed it in the early 1980s, he wanted it to represent "open government." That’s why there’s that giant 17-story atrium. He wanted people to see their government at work. Instead, what they mostly saw were high heating bills and buckets catching drips from the skylights.
The Problem with 100 W Randolph Street
Let’s be real for a second. The Thompson Center was a nightmare to maintain. Because of that massive glass dome and a lack of proper insulation, the building basically acted like a greenhouse in the summer and an icebox in the winter. The state was spending something like $17 million a year just to keep the lights on and the air moving. By the time 2019 rolled around, the "deferred maintenance" bill—which is just a fancy way of saying "stuff that’s broken"—had climbed to nearly half a billion dollars.
Governor J.B. Pritzker eventually decided the state couldn't afford it anymore. They put the building up for sale. For a while, it looked like it might be demolished. Preservationists flipped out. Jahn’s design is polarizing, sure, but it’s also one of the most significant examples of Postmodern architecture in the world. Demolishing it would have been a tragedy for the city's architectural skyline, even if the building was a pain to heat.
Then Google stepped in.
Why Google Wants 100 W Randolph Street Chicago IL 60601
In 2022, Google announced they were buying the building. Well, technically, Google is the end-user, and they’re working with developers Prime Group and Capri Investment Group to overhaul the whole thing. They paid the state $30 million in cash and gave them a title to another building at 115 S. LaSalle St. It was a complex three-way trade. Basically, the state got out of a money pit, and Google got a trophy property that they can turn into a 21st-century tech hub.
Why here? Because 100 W Randolph Street Chicago IL 60601 is uniquely positioned. It sits directly on top of one of the busiest transit hubs in the world. The Clark/Lake station is right inside the building. You can catch the Blue, Green, Brown, Orange, Pink, and Purple lines without even stepping outside. For a company trying to lure thousands of employees back to the office, you literally cannot beat that commute. It’s the ultimate "transit-oriented development."
Google isn't just slapping a logo on the door. They are gutting the place. They’re replacing the entire glass facade. The old single-pane glass—the stuff that made everyone sweat in July—is being swapped for high-performance, energy-efficient glazing. They are also keeping the atrium. Thank god. It’s the building’s best feature. Imagine a tech campus where the "break room" is a 17-story canyon of light. It’s going to be wild.

The Architectural Controversy
Helmut Jahn was a visionary, but he was also a bit of a rebel. When the building opened in 1985, it was a shock to the system. Chicago is a city of stone and steel, of Mies van der Rohe’s "less is more." Jahn did "more is more." He used salmon and light blue colors. He used curved glass. He made it look like a kaleidoscope.
Architectural critics like Blair Kamin have written extensively about the building’s flaws and its brilliance. The main issue was always the execution. The state cut corners on the original construction. They didn't install the specialized double-paned glass Jahn wanted because it was too expensive. That’s why the building failed its occupants. Google has the money to do it right. They are essentially finishing Jahn’s vision, forty years late.
Interestingly, Jahn actually lived long enough to see the building’s potential salvation begin, though he tragically died in a bicycle accident in 2021 before the Google deal was finalized. His firm, Jahn (now led by Francisco Gonzalez-Pulido), is still involved in the redesign. It’s a nice bit of poetic justice.
What This Means for the Loop
For a long time, the LaSalle Street corridor was dying. COVID-19 accelerated that. Banks moved out. Law firms went remote. The "canyon" of LaSalle felt like a ghost town after 5:00 PM.
The revitalization of 100 W Randolph Street Chicago IL 60601 is the catalyst for the "LaSalle Street Reimagined" initiative. The city is pouring money into converting old office buildings nearby into apartments. If you have 2,000 high-paid Google employees working at Randolph and Clark, you suddenly have a reason for restaurants to stay open late. You have a reason for a grocery store to move in. You have a neighborhood.
This isn't just about one building. It’s about whether the center of Chicago can survive the shift to hybrid work. Google is betting billions that it can.
Surprising Facts About the Site
Most people don't realize that before the Thompson Center, this site was home to the Sherman House Hotel. It was one of the grandest hotels in the city. Then, for a brief period, it was just a giant hole in the ground.

Also, the sculpture out front? The "Monument with Standing Beast" by Jean Dubuffet. People call it "Snoopy in a Blender." It’s a polarizing piece of art, but it’s staying. It’s become a symbol of the building’s quirkiness. Google has committed to maintaining the public spaces, which is a huge relief for people who feared the building would become a private fortress. The ground floor will still have retail. It will still be a place where people can walk through.
The Logistics of the Renovation
Construction is currently in full swing. If you walk by today, you’ll see the massive scaffolding and the "blue wrap" that has become a temporary fixture of the skyline. The project is aiming for LEED Platinum certification. That’s the highest rating for environmental design. They are aiming to make it all-electric, which is a massive undertaking for a building of this scale.
The timeline? Google expects to start moving people in by 2026.
It’s a massive project. We’re talking about over a million square feet of office space. To put that in perspective, that’s about twenty football fields stacked on top of each other.
What to expect at 100 W Randolph Street Chicago IL 60601:
- A complete glass replacement to fix the temperature issues.
- A redesigned public plaza that’s actually inviting.
- The Clark/Lake CTA station will remain open and get its own upgrades.
- Modernized elevators (the old ones were notoriously slow).
- A massive influx of tech talent into the central Loop.
Practical Steps for Visitors and Locals
If you’re planning to be in the area, there are a few things you should know.
First, the CTA station is still functioning. Don't be deterred by the construction fences. You can still access the trains.
Second, the "food court" that used to be in the basement is gone. Don't go there looking for a cheap gyro or a Sbarro slice. Those days are over. For food, you’ll want to head a block over to Wells Street or down to the revitalized riverwalk.

Third, if you’re an architecture nerd, this is the best time to see the "bones" of the building. With the old glass coming off, you can see the intricate steel structure that Jahn designed. It’s a rare look at the skeleton of a postmodern icon.
Why This Matters to You
Even if you don't work in tech or live in Chicago, what’s happening at 100 W Randolph Street Chicago IL 60601 is a case study for every major city. It’s an answer to the "doom loop" narrative. It shows that with enough capital and a bit of architectural respect, you can turn a failed government building into a global tech headquarters.
The building was a symbol of 1980s ambition and 2000s neglect. Now, it’s becoming a symbol of the 2020s pivot.
Next Steps for Staying Informed:
