Onni 606 — Three towers.One Bellevue block.Every change tracked.

A three-tower, mixed-use development under construction on the former Barnes & Noble block in Downtown Bellevue — described by local reporting as Washington State's largest construction project. This independent guide follows the public record and the work visible on the block.

Current phase

Early excavation under way — shoring pending

Six excavators and a dozer are spread across a broad, graded early-works area under an issued clear-and-grade permit. Full shored excavation has not started.

Next gate

Limited early grading continues while full excavation, perimeter shoring and below-grade construction remain dependent on separate city approvals.

All updates
  1. July progress report: the cleared block enters early earthworkThe month-to-date record traces a clear transition: remaining surface slab was broken and removed across the block, exposed subgrade widened from a bounded foreground patch to most of the visible site, and the active fleet grew to six excavators plus a dozer by July 21. The work is authorized under the early clear-and-grade permit; it is not yet the deep, shored five-level garage excavation, whose separate permits remain pending.
  2. Six excavators spread across the early-works areaA high-resolution afternoon photograph shows six tracked excavators, a tracked dozer and a water truck across a broader graded area than the July 17 camera frame, which showed four excavators. The northeast slab has been broken into a field of rubble or aggregate and the central/southern grade is smoother and more extensive. Bellevue logged a second erosion-control inspection July 20 as Ongoing under the issued early-grading permit; the shoring and below-grade permits remain pending.
  3. Early excavation begins under issued grading permitCamera frames show excavators working exposed soil across a broad shallow cut and dump trucks moving through the site. Bellevue permit 21-133872-GD was issued for early clear-and-grade work for mass excavation, completed its second preconstruction conference June 17 and received an initial erosion-control inspection July 14. A city review note limits it to early grading: the dedicated shoring and below-grade structure permits remain pending.

The project

A four-acre block, rebuilt at city scale.

Local reporting has described Onni 606 as Washington State's largest construction project. The public record shows why.

On a roughly four-acre block bounded by NE 4th and NE 8th Streets, Onni Group is building three towers — two residential and one office — joined by a shared, three-story podium. The project is widely known as Onni Bellevue or simply the 606 Bellevue towers. Acquired in 2019 for $116M, the former Barnes & Noble site at 606 106th Ave NE is being transformed into one of Downtown Bellevue's largest mixed-use blocks.

The program totals more than 1,289 residences, over 300 hotel suites and roughly 896,000 square feet of office space, wrapped around a 15,000-square-foot public plaza and a segment of Bellevue's Grand Connection. Six excavators and a dozer are spread across a broad, graded early-works area under an issued clear-and-grade permit. Full shored excavation has not started. Limited early grading continues while full excavation, perimeter shoring and below-grade construction remain dependent on separate city approvals.

The civic bargain

What the height gives back.

The headline figure of roughly 4,000 jobs is the city's SEPA estimate — it bundles the temporary construction workforce with the permanent positions the finished office, hotel and retail are expected to support, so it is a measure of activity the block will generate over its lifetime, not a single payroll. The 1,289 homes concentrate new housing near the 2 Line. In exchange for building to the 600-foot ceiling, Onni dedicates a 15,000-square-foot plaza and a landscaped segment of the Grand Connection — public benefits intended to outlive the cranes.
