About this project
Four 106, at 350 106th Ave NE in Bellevue's Downtown, is a 21-story Class-A office building with 8 levels of parking below grade. The site began as a two-tower mixed-use project over a shared podium, carried in a design review (15 123104 LD) and a Master Development Plan (15 123106 LP). A 2018 preapplication conference (18 125373 DB) recast it as an 18-story office building of 420,000 square feet, and a later Master Development Plan (19 130395 LP) split the program into a 17-story office tower and a 7-story office tower totaling 534,770 square feet of office space, 12,750 square feet of retail and 1,083 parking stalls, before the scheme consolidated into the single 21-story tower.
