Microsoft announced Wednesday a major expansion of its Redmond campus that will bring an estimated 3,000 new positions to the city over the next two years, primarily in artificial intelligence and cloud computing divisions.

The tech giant plans to construct two new office buildings on its East Campus, totaling 450,000 square feet of workspace. The buildings will feature sustainable design elements including solar panels, rainwater harvesting systems, and green rooftops.

Company spokesperson David Chen said the expansion reflects Microsoft’s commitment to its Redmond headquarters. “While we have offices worldwide, Redmond is our home.”

City officials say the expansion will generate significant tax revenue and boost the local economy. The Lake Washington School District is already planning for anticipated growth in student enrollment.
