Ever driven past that massive glass-and-steel monolith on the north side of I-88 and wondered what actually happens in there? It’s hard to miss. 3500 Lacey Road Downers Grove IL is one of those buildings that defines the suburban Chicago skyline. It’s got that specific kind of 1990s-meets-modern prestige that looks like it belongs in a movie about a high-powered law firm or a biotech giant.
It’s big. Really big.
We’re talking about roughly 620,000 square feet of office space spread across 13 floors. In a world where everyone says the office is dead, this place seems to be doing just fine. Why? Because it’s not just an office. It’s Esplanade II, a cornerstone of the Hamilton Partners’ master-planned Esplanade at Locust Point. If you’ve spent any time in the East-West Tollway corridor, you know this is the "Main and Main" of suburban business.
The Architecture of a Power Move
Walking into the lobby of 3500 Lacey Road Downers Grove IL feels exactly how it was designed to feel: intimidating but professional. It has these soaring ceilings and high-end finishes that remind you of an era when companies built monuments to their own success. But it’s surprisingly functional. Unlike some of those older buildings in Oak Brook that feel cramped and dark, the floor plates here are expansive.
The light is the real kicker.
Because the building is encased in glass, the natural light pours in from every angle. It’s one of those design choices that was ahead of its time. Back in 1992, when it was completed, "wellness" wasn't a corporate buzzword yet, but they inadvertently nailed it by making sure employees weren't stuck in windowless cubicles. The building was designed by the architectural firm Skidmore, Owings & Merrill (SOM). If that name sounds familiar, it should. They’re the same folks behind the Willis Tower and the Burj Khalifa. You can see that DNA in the structural integrity and the timelessness of the facade.
Who Actually Works at 3500 Lacey Road?
For a long time, this building was synonymous with Sara Lee. Remember them? They moved their headquarters here back in the mid-2000s, bringing a massive influx of jobs to Downers Grove. It was a huge deal for the local economy. When Sara Lee eventually split into Hillshire Brands and D.E. Master Blenders, the footprint changed, but the building’s reputation stayed solid.
Today, it’s a bit more of a mix. You’ve got giants like Havis, and for a while, it served as a major hub for companies like Univar Solutions.

It’s interesting to see how the tenant mix has shifted. You used to have these massive 100,000-square-foot blocks taken up by a single entity. Now, it’s a bit more fragmented, which is actually healthier for the building's long-term survival. If one company goes under or moves to the city, the whole ecosystem doesn't collapse.
The Location is Basically Unbeatable
Let’s be real: suburban office space lives and dies by its proximity to the highway. 3500 Lacey Road Downers Grove IL is basically hugging the I-88 and I-355 interchange. You can get to O'Hare in 25 minutes if the traffic gods are smiling on you. You can get to the Loop in 30.
But it’s not just the road access.
The building is part of a larger ecosystem. You’ve got the DoubleTree by Hilton right there for out-of-town clients. There’s the Morton Arboretum just down the road for when you need to clear your head after a four-hour meeting. And the food? You aren't stuck with just a vending machine sandwich. Between the on-site deli and the proximity to Butterfield Road, you’ve got everything from high-end steakhouses to decent tacos within a five-minute drive.
What it Really Costs to Be Here
If you’re looking to lease space at 3500 Lacey Road, you aren't looking for "budget" space. You’re looking for Class A. In the Downers Grove market, Class A rents have fluctuated, but this building consistently commands a premium. You’re usually looking at triple-net (NNN) leases where the base rent might look one way, but when you add in the taxes and operating expenses—which are significant for a building of this scale—the "all-in" number can be eye-opening.
The building is currently managed by some of the heavy hitters in commercial real estate, often changing hands between REITS or massive investment groups like Blackstone or KRE-REIT. This means the maintenance is usually top-tier. The elevators work. The HVAC doesn't leave you sweating in July. The parking garage isn't crumbling.
The Amenities Arms Race
In 2026, you can't just offer a desk and a chair. 3500 Lacey Road has had to evolve. They’ve invested heavily in the fitness center, which honestly rivals some boutique gyms in the area. There’s also the conference center. If you’re a mid-sized firm and you need to host a 100-person seminar, you don't have to rent out a hotel ballroom; you just go downstairs.

There is a certain "vibe" to the cafe area during lunch. It’s a lot of blue blazers and tech-casual Patagonia vests. It’s a networking hub without trying too hard to be one.
One thing people overlook is the outdoor space. There’s a terrace and some walking paths around the pond. It sounds like a small thing, but when you’re grinding through a 60-hour work week, being able to sit by a body of water for fifteen minutes is a lifesaver.
Common Misconceptions About the Lacey Road Area
People often confuse 3500 Lacey with the neighboring buildings in the Esplanade complex. While they share a similar aesthetic, 3500 is the "big brother." Some folks also think it’s part of Lombard because it’s so close to the border, but it’s firmly within Downers Grove limits.
Another weird myth? That the building is half-empty.
While the "office apocalypse" did hit some suburban parks hard, the Lacey corridor has stayed remarkably resilient. The vacancy rates here are often lower than the national average for suburban Class A properties. High-quality buildings tend to "suck the air out of the room," attracting tenants from lower-quality buildings who want to upgrade their image.
Why Small Businesses Struggle Here
If you’re a three-person startup, 3500 Lacey Road might not be your speed. The floor plates are huge. While they can subdivide, the building is really geared toward "trophy" tenants. It’s for the company that has made it, or the one that needs to look like it has.
The security is also tight. You aren't just wandering in here without a badge or a reason to be there. This is great for the tenants, but it can be a bit of a hurdle for casual visitors.

How to Navigate a Visit
If you have a meeting here, give yourself an extra ten minutes just for the parking and the lobby check-in. The parking deck is massive, and if you park on the wrong level, you’ll be walking a country mile before you even hit the front door.
- Enter via Lacey Road or Woodcreek Drive.
- Use the visitor parking slots specifically marked near the entrance to the deck.
- Have your ID ready at the security desk.
- The elevators are banked by floor; make sure you get in the right one or you’ll end up on the 12th floor when you needed the 4th.
The Future of 3500 Lacey Road
What happens next? As we move deeper into the late 2020s, the focus is shifting toward sustainability. 3500 Lacey has already made strides with LEED certifications, but the pressure is on to keep reducing the carbon footprint of these massive glass structures.
Expect to see more EV charging stations in the garage. Expect more smart-building technology that tracks occupancy to save on heating and cooling.
The building is a survivor. It survived the 2008 crash, the Sara Lee departure, and the 2020 shift to remote work. It remains a "gold standard" because it offers something a home office can't: a sense of scale and institutional stability.
Actionable Next Steps for Business Owners
If you are considering moving your operations to the Downers Grove area, specifically looking at a high-profile spot like 3500 Lacey Road, here is the playbook:
- Audit your space needs honestly. Don't over-lease. The trend is "flight to quality, but smaller footprint." You might only need 10,000 square feet now instead of 20,000.
- Negotiate the "work-letter." Since these spaces are Class A, you can often negotiate for the landlord to handle the build-out costs to get the office exactly how you want it.
- Check the sub-lease market. Sometimes a larger tenant at 3500 Lacey will have a floor or a wing they aren't using. You can often get a "deal" by taking over their lease at a lower rate than the primary landlord would charge.
- Talk to a local broker. Don't try to navigate Hamilton Partners or the current REIT owners alone. You need someone who knows the "effective rate" (the price after all the free rent and concessions are baked in).
- Visit at 8:30 AM and 5:00 PM. You need to see the traffic flow. Lacey Road is efficient, but the I-88 on-ramps can be a beast during the morning rush.
This building isn't just an address. It’s a statement of intent. Whether you’re working there or just passing by on the tollway, it stands as a reminder that the Chicago suburbs are still a massive engine for American business.
