Renovations Completed at Seattle Mixed-Use Campus

The Seattle market has gained 300,000 square feet of life science lab, R&D and Class A office space with the completion of renovations at Unison Elliott Bay, a three-building mixed-use campus located at 351, 401 and 501 Elliott Ave. West.

Renovations began at the property, which is owned by Office Properties Income Trust and managed by The RMR Group, in March 2022. Located in the Uptown submarket, the property is within 2 miles of downtown Seattle.

The lab space includes speculative suites as well as customizable space. The campus already has one tenant, biotechnology firm Sonoma Biotherapeutics Inc., which signed a 10-year lease for more than 83,000 square feet in August 2022. Sonoma Biotherapeutics occupies three floors of office and lab space in the 501 building for its R&D and Manufacturing Center, intended for the development of engineered regulatory T cell therapies for autoimmune and inflammatory diseases. The biotech company has moved its Seattle operations to Unison and plans to hire an additional 100 employees.

Campus Features, Amenities

In addition to the Class A office space, Unison Elliott Bay has 200,000 square feet of 14-foot floor-to-floor heights in two dedicated lab buildings which include move-in ready lab and R&D space with suites ranging from 12,500 to 25,000 square feet. The property includes dedicated mechanical infrastructure supported by standby generator power to accommodate demanding lab and technological power requirements. It integrates energy-efficient systems and green features such as green walls of preserved moss that are installed in the reception areas to add vitality to the lobbies and connect occupants to the natural surroundings. Felt matrix ceilings offer enhanced sound attenuation.

Unison Elliott Bay has indoor and outdoor meeting areas, conference and training rooms, fitness and changing room facilities, as well as a landscaped courtyard. Covered and surface parking are available along with secure bike storage and EV charging stations. Tenants will also be able to dine at a chief-driven café or a rotating mix of food trucks.

The campus, which is on track to achieve LEED Gold, Fitwel and Wired Score certifications, is situated along Elliott Bay with views of Puget Sound and the Olympic Mountains. Occupants will have access to 15 acres of nearby trails, beaches and open space at Myrtle Edwards and Centennial parks.

Managing Director Joe Gowan and Senior Vice President Tim Jones of JLL’s Life Sciences Team are leading leasing efforts for the campus.

Unison is managed by RMR, a leading alternative asset management company which is responsible for providing all aspects of management services and strategy for more than 2,000 properties across the United States including life science, office, industrial, medical office, retail, hotel, multifamily and senior living assets.

Late last year RMR and OPI unveiled the redeveloped 20 Mass in Washington, D.C. Formerly a government office building, OPI converted the asset into a 10-story, 427,191-square-foot mixed-use tower with office, retail and amenity spaces and a hotel in a $200 million renovation project.

RMR manages OPI, which owns or leases 152 properties totaling approximately 20.5 million square feet in 30 states and D.C.
