The hole is finally being filled. For over a decade, if you walked near the intersection of the Chicago River and Lake Michigan, you were greeted by a massive, fenced-off pit. It was a bruise on the skyline. People called it the "Spire Hole," a remnant of the 2,000-foot-tall dream that died during the 2008 financial crisis. But now, 400 Lake Shore Drive Chicago is becoming something real, and honestly, it’s about time.
Construction is finally moving. You can see the cranes. This isn't just another glass box being shoved into a vacant lot; it's the reimagining of the most valuable piece of undeveloped land in the city. Related Midwest is the developer behind this massive $1.6 billion project, and they aren't trying to build the tallest building in the world this time. They're building two towers that actually make sense for the way Chicago looks now.
It’s weird to think about how much history is buried in that dirt. The site was originally meant to host the Chicago Spire, designed by Santiago Calatrava. It would have been a twisting, needle-like skyscraper. Instead, the developers went bust, the hole filled with rainwater, and it became a local meme. Now, the new design by Skidmore, Owings & Merrill (SOM) is taking over. David Childs, the guy who designed One World Trade Center, is the lead architect here. He’s opted for something that feels more "Chicago"—heavy on the limestone, glass, and metal, with a "sister tower" layout that frames the lakefront rather than trying to pierce the clouds.
Why 400 Lake Shore Drive Chicago Is More Than Just Luxury Condos
People usually roll their eyes when a new "luxury" development gets announced. I get it. We have enough $5,000-a-month apartments. But this project is different because of the public infrastructure involved.
Basically, as part of the deal to build these towers, Related Midwest has to fix the mess surrounding the site. This includes finishing DuSable Park. This 3.3-acre park has been a "planned" project since the 1980s. It’s named after Jean Baptiste Point du Sable, the founder of Chicago. For forty years, it’s been a patch of weeds and radioactive thorium (left over from an old gas mantle factory). The developers are spending roughly $10 million to finally remediate the soil and turn it into a public space that connects the Riverwalk to the lakefront.
Then there’s the "Founders Way." It’s a planned pedestrian bridge that will link the Chicago Riverwalk directly to the new park. If you’ve ever tried to walk from the river to the lake in that area, you know it’s a nightmare of traffic and dead ends. This bridge changes the entire flow of the city.
The north tower is going up first. It’ll stand 72 stories tall. Inside, you’re looking at 635 apartments. Some are affordable housing units—about 127 of them, scattered throughout the building. That was a big win for the city during the zoning negotiations. The south tower will follow later, adding another 500 units, likely as condos.

The Engineering Headache Nobody Talks About
Building on the edge of the lake isn't like building in the Loop. The ground is soft. The wind is brutal. To keep 400 Lake Shore Drive Chicago from literally sinking or swaying too much, they’ve had to rethink the foundations.
The original Spire cofferdam—that famous 76-foot-deep hole—is actually being repurposed. Instead of filling it in and starting over, engineers are integrating it into the new structure. It’s a massive circular concrete wall that goes deep into the bedrock. They’re using it for the tower’s "feet." It’s a clever bit of recycling, honestly.
The towers themselves have these "lantern" tops. At night, they’ll glow. But the real architectural flex is the "shingled" glass. The windows aren't flat; they’re angled slightly to mimic the way light hits the ripples of Lake Michigan. It’s subtle. You might not notice it from a mile away, but up close, it gives the building a texture that most modern skyscrapers lack.
The Business Reality of the Chicago Skyline
Let's talk money and timing. Why now? Why did this site sit empty for 15 years?

Interest rates are high. The office market in Chicago is, frankly, struggling. But residential demand in the Streeterville and Lakeshore East neighborhoods is still through the roof. Related Midwest secured a $500 million construction loan—one of the largest in the country recently—to get the first phase started. That tells you the big banks (like BMO and Wells Fargo) believe people still want to live right on the water.
- Phase 1: The 858-foot North Tower.
- Public Benefit: Completion of DuSable Park and the lakefront link.
- Job Creation: Thousands of construction jobs over the next few years.
- Tax Revenue: Once finished, the property tax bill on this site will be astronomical, which the city desperately needs.
Some critics argue that the towers are too bulky. They miss the "elegance" of the Spire. But elegance doesn't pay the bills, and elegance doesn't provide a public park. The SOM design is practical. It’s sturdy. It looks like it belongs in a city built on steel and masonry.
What This Means for Your Commute and Property Values
If you live in Streeterville or New Eastside, expect noise. A lot of it. Construction on a project this size involves constant trucking and lakefront activity. But the payoff is the property value. Closing that gap in the Riverwalk makes the entire area more "walkable," which is the gold standard for urban real estate right now.
You've got the Navy Pier crowds to the north and the quiet residential vibe of Lakeshore East to the south. This project sits right in the middle. It’s the "missing link."
Practical Steps for Following the Progress
If you're interested in the development or thinking about renting there once it opens in 2027, here’s what you should do:

- Monitor the Riverwalk Extensions: Keep an eye on the Chicago Department of Transportation (CDOT) bulletins regarding the Founders Way bridge. This will dictate when the lakefront becomes fully accessible.
- Check the Affordable Housing Registry: If you're looking for one of the 127 "set-aside" units, you'll need to watch for the lottery announcements through the Chicago Department of Housing. These usually open up about 6-12 months before the building is finished.
- Visit the Site Now: Go to the end of the Riverwalk near the Lake Shore Drive bridge. You can see the foundation work happening in the old Spire hole. It’s a rare chance to see "mega-scale" engineering before it gets covered up by drywall and luxury finishes.
- Follow Related Midwest’s Updates: They occasionally release drone footage of the progress. It’s the best way to see the "shingled" glass installation as it begins on the lower floors.
400 Lake Shore Drive Chicago isn't just a building. It's the closing of a chapter of failure for the city and the start of a much more grounded, realistic era of lakefront development. It might not be the tallest building in the Western Hemisphere, but it's actually getting built, and that's a much better story.
The transformation of this site will take years. The North Tower should be enclosed by late 2026, with the first residents moving in by early 2027. By then, the "Spire Hole" will be a memory, replaced by a silhouette that finally completes the mouth of the Chicago River.
