The RMR Group has completed Unison Elliott Bay, a three-building mixed-use campus in Seattle that includes 300,000 square feet of life science lab, R&D and Class A office space.
Located at 351, 401 and 501 Elliott Avenue West, Unison is owned by RMR client Office Properties Income Trust, a national REIT focused on owning and leasing office properties.
The campus features Class A office space and 200,000 square feet of 14’ floor-to-floor height in the two dedicated lab buildings. This includes move-in-ready lab and R&D space with suites ranging from 12,500 to 25,000 square feet.
Sonoma Biotherapeutics, Inc., a clinical-stage biotechnology company, has signed a 10-year lease in the 501 building for more than 83,000 square feet. The biotech company has moved its Seattle operations to Unison and plans to expand headcount and hire an additional 100 employees.
Unison is managed by RMR, and JLL’s Life Sciences Team of Joe Gowan, Managing Director and Tim Jones, Senior Vice President are leading leasing efforts for the campus.
