It looks like Amazon is really digging into the whole returning-to-its-roots-thing by adding scores of new jobs to the city Jeff Bezos started the company in 25 years ago. With an incoming 600-foot-tall skyscraper slated to host thousands of employees in Bellevue, Washington, the Seattle-adjacent city will soon become home to one of the largest offices towers in the company’s history.

The Seattle Times reported that the giant online retailer and its main architect, NBBJ, recently filed a pre-application for Bellevue 600, a 43-story, one-million-square-foot office tower that could house up to 4,200 employees. Located just 10 miles east from its downtown Seattle headquarters—a mere hop across Lake Washington, the proposed project seems to cement Amazon’s expanding footprint in Bellevue. It already owns a 354,000-square-foot building called Centre 425, which it bought in 2017 and now accommodates 500 positions. It’s also currently renting space from WeWork in another downtown location.

Last summer, Amazon signed a lease for offices in the former Expedia headquarters, which will begin next year. It also just secured square footage in a planned 17-story story building designed by LMN Architects, according to GeekWire. It’s been said that Bellevue 600, the largest of all these office spaces, would be built atop a future transit and light rail station that could easily connect employees with the Seattle home base.

While Seattle is practically synonymous now with Amazon, Bezos actually began the company out of his garage in Bellevue in 1994. It’s a little-recognized fact that, when put in the context of the company’s current clashes with Seattle city government, makes sense for Amazon’s next big move. Belleuve is already emerging as a major tech hub—Google, Facebook, T-Mobile, and even Expedia have leased space in and around downtown Bellevue, according to Geekwire. And local politicians are welcoming them in. But just because it’s gobbling up leases in the Eastside city doesn’t mean Bellevue is the site of HQ2, or that it’s halting expansion in Seattle.

Regardless of the intention behind it, Amazon’s real estate portfolio is rapidly growing. Set for completion in 2024, Bellevue 600 would provide room for the entirety of Amazon’s Worldwide Operations division, according to The Seattle Times. This includes all of the personnel that handle the delivery and logistics of each package that a customer orders, and the operations of the company’s 175 global fulfillment centers.

Details on the design or development of the structure have not been released, but it’s been reported that, based on NBBJ’s proposal, the tower would include 885,000 square feet of office space atop a podium with room for retail, “office amenity” space, and a meeting center. Several pedestrian plazas would envelop the outdoor space as well. There’s even speculation of another tower planned for the site, which Amazon has yet to fully confirm.
