There are two components to Amazon’s Bellevue 600 project, at 600 and 640 108th Ave. N.E. in downtown Bellevue. Phase I, the 43-story east tower, is now underway. That project replaced an old structured parking garage. It’ll probably open in 2024, after the 2023 opening of Bellevue Downtown Station, practically at its doorstep.

Phase II, the 31-story west tower, will replace the over 40-year-old Bellevue Corporate Plaza building, on the corner of 108th and Northeast Sixth Street. NBBJ is also designing that tower, which last week received a SEPA determination of non-significance from the city. That moves it closer to final permits. The public appeal period ends Jan. 13.

This view looks west at the Phase II Tower, with the green canopies of the old Bellevue Transit Center in the foreground.  The corner of the Phase I podium is peeking out at right.


Sellen, the builder of Phase I, is also attached to Phase II. Its project numbers are all about the same: 764,368 square feet of offices; 13,821 square feet of retail/commercial space; a 7,064-square-foot childcare center; a shared plaza between the buildings with about 18,000 square feet; and six levels of underground parking with 718 stalls. The latter will connect to the Phase I garage, for a total of 1,718 stalls. Office workers will also have around 1,000 bike stalls.

Combined, the two towers will have around 1.5 million square feet for around 7,000 Amazon workers. The entire project is targeting LEED Gold certification.

For Phase II, Amazon’s SEPA filings mention a start date in 2022, with occupancy in 2025. The pandemic and supply chain issues may complicate that timeline. It’s also unclear how many tenants remain at Bellevue Corporate Plaza, and how fast those leases are expiring. Having acquired the entire 3.5-acre property for $195 million in 2019, Amazon may have inherited early-termination clauses in its interim role as landlord.

The team for all of Bellevue 600 includes Seneca Group, development manager; GeoEngineers, geotechnical; GGN, landscape architect; Coughlin Porter Lundeen, civil engineer; Magnusson Klemencic Associates, structural; McKinstry, mechanical, plumbing and energy modeling; Stantec, electrical; Bush, Roed & Hitchings, surveyor; Code Consultants, fire and safety; and Lerch Bates, elevators.
