The RMR Group announced the redevelopment of 351, 401 and 501 Elliott Avenue West in Seattle into Unison Elliott Bay, a three building mixed-use development with more than 300,000 square feet of LEED certified Class A office and life science lab space. Located near the new Climate Pledge Arena and 15 acres of winding trails, beaches and open space at nearby Myrtle Edwards and Centennial Parks, Unison's natural surroundings will encourage workplace creativity and productivity. Upon delivery, Unison will be tailored for the next generation of office and life science users.

Unison's design offers unique opportunities for tenants, with 21,000-27,500 square feet of customizable floor plates across the three buildings, and 200,000 square feet of 14' floor-to-floor heights in the two dedicated lab buildings. Campus features include an outdoor lounge, conference and training rooms, fitness facility, new lab mechanical infrastructure and two backup generators to accommodate demanding lab and technological needs. Covered and surface parking, bike storage and EV charging stations throughout the property are designed to address transportation needs for Unison's tenants.
