Walk out of the Silver Spring Metro station and look up. You can't miss it. 8403 Colesville Road Silver Spring—better known to locals and commuters as the Discovery Building—is more than just a massive hunk of glass and steel sitting at the intersection of Colesville and Georgia Avenue. It’s the visual anchor of a city that spent decades trying to figure out if it wanted to be a sleepy suburb or a high-octane urban hub.
Honestly, it’s kind of a marvel.
For years, this specific address wasn't just an office; it was a symbol of Maryland's economic ambition. When Discovery Communications moved its global headquarters here from Bethesda in the early 2000s, it changed everything. It wasn't just about jobs. It was about the giant inflatable shark they’d stick on the side of the building for Shark Week, a sight that basically became a regional holiday for anyone stuck in Montgomery County traffic.
But things changed. They always do. Discovery packed up for New York City, leaving a massive hole in the heart of downtown. People worried. They thought the building would sit empty, a ghost of corporate past. Instead, 8403 Colesville Road did something unexpected: it evolved.
The Architectural Weight of a Landmark
Designed by SmithGroup, the building at 8403 Colesville Road wasn't built to be subtle. We’re talking about over 500,000 square feet of Grade A office space. It’s got that sweeping, curved facade that mimics the flow of the streets it borders. It’s weirdly beautiful in the afternoon light when the sun hits the glass just right, reflecting the chaotic energy of the bus station below.
Most people don't realize the complexity of the site. It’s a transit-oriented development masterclass. You have the Red Line and the MARC train literally steps away. Then there’s the future Purple Line, which is currently a mess of construction but promises to make this corner even more accessible.
Inside, the floor plates are huge. That's why it was so attractive to a media giant. You need room for editing bays, massive servers, and hundreds of creative types who need to collaborate without hitting a wall every five feet. The building features a tiered structure, meaning those lucky enough to work on the upper levels get terraces that look out over the D.C. skyline. On a clear day? You can see the Washington Monument.

What Happened After the Shark Left?
When Discovery announced its exit in 2018, the local economy felt a collective shudder. You can’t just lose 1,000-plus high-earning employees and expect the nearby sandwich shops to stay afloat. But the real estate world moves fast. Foulger-Pratt and Cerberus Capital Management stepped in, rebranding the site as "Inventure."
They didn't just slap a new name on the door. They poured millions into making it a multi-tenant powerhouse.
Today, the building is a mix. It’s no longer a one-company town. Children’s National Hospital took a massive chunk of space for their Telehealth and Innovation Center. Think about that for a second. Instead of Shark Week, the building is now housing the future of pediatric medicine. It’s a pivot from entertainment to essential services, which is sort of the story of Silver Spring itself.
It’s also home to various non-profits and tech firms. By diversifying the tenant base, 8403 Colesville Road actually became more resilient. If one company goes under or moves, the whole building doesn't go dark. It’s a smarter way to manage a landmark.
The "Sensory" Experience of the Location
If you’re visiting 8403 Colesville Road Silver Spring, you aren't just going to an office. You're entering a ecosystem.
Directly across the street is the Silver Spring Transit Center. It’s loud. It’s busy. You’ll hear the hiss of air brakes and the chatter of thousands of people. But then you walk a block over to Ellsworth Drive, and it’s a total vibe shift. You have the AFI Silver Theatre showing 70mm prints of old classics, and the Fillmore Silver Spring hosting metal bands or indie rappers.

Misconceptions About the Address
One thing people get wrong is thinking this building is "just for offices." While the upper floors are strictly business, the ground level and the surrounding plaza are meant to be porous. The "Discovery Garden" area was a big deal—a public-private space that offered a bit of greenery in an asphalt jungle.
Another mistake? Thinking it’s hard to get to.
Yes, Georgia Avenue is a nightmare during rush hour. Everyone knows that. But the beauty of 8403 Colesville Road is that you don't have to drive. It was designed specifically to get people out of their cars. If you're driving to this building every day, you're doing it wrong. Take the train.
Why It Matters for the Future of Silver Spring
Silver Spring has always been D.C.'s scrappy younger sibling. It doesn't have the polish of Bethesda or the history of Alexandria, but it has heart. 8403 Colesville Road is the anchor of that heart.
As the Purple Line nears completion—whenever that actually happens—the value of this specific plot of land is only going to skyrocket. We are looking at a future where this building connects the University of Maryland at College Park directly to the heart of Montgomery County’s business district.
