Excavation on the 606 Bellevue Tower project is scheduled to begin in July 2026, according to Amir Gharoon of Onni Group. The development, located at 606 and 620 106th Avenue Northeast, is expected to be the largest construction project in Washington state, with an estimated construction timeline of close to five years.
The mixed-use project will consist of three towers reaching approximately 600 feet in height atop a large podium structure. Plans include more than 1300 apartment units, over 400 hotel suites, and approximately 896,000 square feet of office space.
Additional amenities are expected to include a daycare, two swimming pools, commercial retail space, and a 15,000-square-foot public open space. The project will also incorporate a 30-foot-wide segment of Bellevue’s Grand Connection and a through-block pedestrian connection.
The development sits on the former Barnes & Noble site, a roughly four-acre parcel that Onni Group acquired in 2019 from Sterling Realty Organization for $116 million.
The City of Bellevue approved the Master Development Plan and Design Review for the project in June 2022. Barnes & Noble relocated to Crossroads Mall later that year, and Doxa Church, which had occupied the site for seven years, moved to Redmond in April 2022.
Both structures are planned for demolition as part of the redevelopment.
According to the City of Bellevue’s SEPA Environmental Checklist, the completed project could support upwards of 4,000 workers across its office, hotel, and retail components.
