9th & Stewart Life Sciences Building
Address: Seattle, WA
Company/Developer: Touchstone Corporation
General Contractor: Lease Crutcher Lewis
Property Type: Life Sciences
Square Feet: 215,000 square feet
Height: 11 stories
Building Description: This rigid concrete and steel building features 15’ floor-to- ceiling heights and column spacing designed for lab module use; space designed for up to 15–20 air changes per hour; chiller space capacity for up to 2,100 tons; and three passenger elevators plus one dedicated freight elevator with a 5,000 lb. load capacity.
Located in downtown Seattle’s rapidly growing Denny Triangle neighborhood, the 9th & Stewart Life Sciences Building merges the practical with the desirable—blending environmental considerations with creative solutions that enhance both the project’s overall value and continued efficiency. The 11-story, 215,000-square-foot biotechnology research and development building includes 212,000 square feet of rentable lab and office space, secured parking for 200 cars and 4,000 square feet of ground-level retail space.
Named NAIOP Washington State Chapter’s 2004 Technology Building of the Year and 2004 Real Estate Deal of the Year, and SIOR’s 2004 Office Development of the Year, this project is a candidate for the Silver LEED Core and Shell rating as a pilot project—a rare accolade for a commercial building.
Bucking Economic Trends
As an independent, regional developer, Touchstone Corporation bucked development trends—an economic downturn and high vacancy rates—to build green. They landed a 15-year lease with Glaxo Smith Kline (formerly Corixa Corporation) for 65 percent of the building’s rentable space.
By planning energy-efficient features early in the design phase, Touchstone was able to incorporate them at greatly reduced cost. They also received financial incentives from Seattle City Light and BetterBricks, an initiative of the Northwest Energy Efficiency Alliance. Currently leased at 75 percent, Touchstone projects a return on investment of $1–$2 per square foot on operating expenses.
