The project

The largest construction project in Washington State.

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. Acquired in 2019 for $116M, the former Barnes & Noble site is being transformed into one of Downtown Bellevue's defining addresses.

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. Excavation is slated to begin in July 2026, kicking off a build of close to five years.

Impact

What it means for Bellevue.

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 land in a downtown that has struggled to add housing fast enough to match its job growth; concentrating that many residences on transit near the 2 Line is the kind of supply Bellevue's own growth targets call for. And in exchange for building to the 600-foot ceiling, Onni dedicates the lasting public benefits that outlive the cranes — a 15,000-square-foot plaza and a landscaped segment of the Grand Connection, the pedestrian spine the city is stitching from downtown to the waterfront.
