Walk through the South Lake Union neighborhood in Seattle and you’ll feel it. The hum of servers, the smell of overpriced espresso, and the brisk pace of people wearing blue badges. It’s the "Amazonia" effect. But if you want to find the literal ground zero of how Jeff Bezos turned a bookstore into a global behemoth, you have to stop at 410 Terry Avenue North Seattle WA 98109.
Most people just call it the Day 1 North building.
It’s not just an address. It’s a philosophy etched into glass and steel. For years, this specific coordinate has served as a cornerstone of the Amazon urban campus, representing a radical shift in how corporate America interacts with city life. While Google and Apple were busy building "spaceships" and isolated fortresses in suburban California, Amazon decided to embed itself right into the grit of Seattle’s old industrial laundry district.
The Architecture of Day 1
When you look at 410 Terry Avenue North, you aren't looking at a skyscraper. It’s an eight-story mid-rise. It doesn't scream for attention like the nearby Spheres, but it’s arguably more important to the daily grind of the company’s operations. The building comprises about 320,000 square feet of office space. That's a lot of desks.
The design, handled largely by CallisonRTKL and developed by Vulcan Real Estate (the late Paul Allen’s firm), was intentional. They wanted "transparency." You see huge windows. You see steel beams. It’s a nod to the "Day 1" mentality—the idea that even though Amazon is a titan, it should act like a scrappy startup that just moved in yesterday. Honestly, the interior vibe is exactly what you’d expect: open floor plans, whiteboard walls everywhere, and those famous "door desks" that became part of the company's lore.
Why this specific block matters
Seattle’s 98109 zip code changed forever because of this building and its siblings. Before the tech boom, South Lake Union was a collection of warehouses and parking lots. Now? It’s one of the densest tech hubs on the planet.

410 Terry Avenue North Seattle WA 98109 sits right in the middle of a massive ecosystem. To the south, you have the main HQ towers. To the west, the waterfront. It’s a logistical masterpiece. Employees can walk from a meeting at Day 1 North to a sync at the Brazil building in five minutes. This "walkability" wasn't an accident. It was a play to keep talent from being stuck in the legendary I-5 traffic.
But it’s not all sunshine and software updates. The presence of 410 Terry Ave N has been a lightning rod for local debate. You’ve got the "Amazon Tax" discussions, the skyrocketing rent in the 98109 area, and the feeling among some long-term Seattleites that the city has lost its soul to the cloud. You can’t talk about this building without acknowledging the tension. It’s the epicenter of a wealth explosion that has pushed others to the margins.
What’s actually inside?
People always ask: "What do they actually do in there?"
It’s not a warehouse. You won't find packages being sorted at 410 Terry Ave N. Instead, this is where the brains live. Historically, this building has housed various core teams, including groups tied to Amazon Web Services (AWS) and the Kindle divisions. It’s high-level product management. It’s where the code that runs half the internet gets debated over lukewarm catering.
The ground floor is where the public actually interacts with the space. Unlike the secretive campuses of the past, Amazon buildings usually feature retail on the street level. You’ll find restaurants and coffee shops that are packed with tech workers at 11:45 AM. It makes the building feel less like a fortress and more like a part of the neighborhood, even if that neighborhood feels like it was built specifically for the people inside those glass walls.

Navigating the 98109 Logistics
If you’re visiting or have a meeting at 410 Terry Avenue North Seattle WA 98109, parking is your first hurdle. Don't even try to find a spot on the street. It’s a nightmare. The building has an underground garage, but it’s mostly for employees. Most visitors end up in the nearby "Discovery" or "Ruby" lots.
Public transit is actually the way to go here. The South Lake Union Streetcar (affectionately or mockingly known as the SLUT) stops just a few blocks away. It connects the campus to the Westlake transit hub. It's a very "Seattle" experience—sitting on a streetcar next to someone debating the latency of a new API.
The Real Estate Reality
Let’s talk numbers, but keep it simple. The valuation of properties like 410 Terry Ave N is astronomical. When Amazon moved in, they didn't just rent; they fundamentally shifted the land value of the entire northern half of downtown.
The building is owned by institutional investors now, often changing hands in billion-dollar portfolio deals. For example, back in the day, the sale of these SLU assets to entities like Union Investment (a German real estate fund) broke records for price-per-square-foot in Seattle. It proved that Seattle wasn't just a regional player; it was a global institutional real estate darling.
Misconceptions about 410 Terry Ave N
One common mistake people make is thinking this is the "main" headquarters. Amazon doesn't really have one single "front door." While the Spheres get all the Instagram tags, the heavy lifting happens in buildings like 410 Terry.

Another misconception? That it’s a closed-off corporate campus. While you need a badge to get past the elevators, the plazas around the building are public. You can sit on the benches, use the Wi-Fi, and watch the dogs. Amazon is famously dog-friendly, and 410 Terry is no exception. You’ll see more Labradoodles than suits in the lobby. It’s a weird, specific culture that defines the 98109 lifestyle.
The Future of the Address
Post-2020, the "return to office" mandates have made 410 Terry Avenue North a focal point of corporate drama. There were walkouts. There were protests. For a while, the building was a ghost town. Now, the lights are back on. The company has doubled down on the idea that physical presence at places like 410 Terry is essential for "innovation."
Whether you love the impact of big tech or loathe it, this building is a monument to the modern economy. It’s where the physical world of real estate meets the invisible world of the cloud. It’s a place where billions of dollars in market cap are managed within a few blocks of an old-school REI flagship store.
