The University of Washington is set to rip out one of central campus’s midcentury holdovers and swap it for a five-story chemistry hub, with ground officially breaking this fall on a new Chemical Sciences Building. The project will wipe out the aging Chemistry Library site, pull scattered labs and classrooms out of Bagley Hall and other spaces, and bring them together under one roof. Crews have already fenced off the construction zone, and the university is targeting an opening in early 2029.
Project size, budget and design
The price tag lands at about $191 million, according to the UW Architectural Commission. Trade coverage has noted the new structure will rise on the current Chemistry Library site at 3923 Okanogan Lane NE and pull together research space that now lives in Bagley Hall. UW has opted for a design-build delivery model, which means architects and builders will be working in tandem to refine the final layout rather than handing off a finished design.
Timeline and construction details
Temporary fencing went up in June 2026, with demolition of the old library slated for later in the summer and vertical construction scheduled to follow this fall, according to UW Facilities. The project page pegs the new facility at roughly 104,500 square feet spread across five floors and reiterates that construction is expected to wrap in early 2029. UW Facilities also lists Skanska and its design partners as the core design-build team on the job.
Money and who pays
State and university dollars are footing the bill. “We received a $124M capital appropriation from the Washington State Legislature for this building,” the Department of Chemistry said in a July update, referencing language in the 2025–27 state capital budget that groups funding under “Chemical Sciences & Bagley Hall” as part of UW’s broader capital package. The rest of the roughly $191 million budget will be covered by a mix of university contributions and private donor support.
What comes down, and what changes on campus
The midcentury Chemistry Library, dating back to the 1950s, is headed for demolition to clear the site, while Bagley Hall is lined up for partial renovation as the program shuffle plays out, according to local trade reporting. The Daily Journal of Commerce has also highlighted early concepts to connect the new Chemical Sciences Building directly to Bagley Hall so research groups and students can be clustered together instead of scattered across multiple wings. UW planners say the overall reshuffle is meant to open up, modernize and centralize laboratory space for both teaching and research.
Why it matters for Seattle's research economy
UW leadership is pitching the project as more than just a shiny new science building. Chemistry department leaders argue the facility is critical for bringing in and keeping top faculty and students and for shoring up regional industries that rely heavily on chemical sciences, including biotech and semiconductor manufacturing. Internal materials frame the building as a dense mix of wet labs, collaboration areas and high-flex classrooms, all designed to expand hands-on training and interdisciplinary research that feed Washington’s workforce pipelines.
Next steps and where to follow progress
Design work will continue through the rest of the year while demolition proceeds on the old library site, with more detailed renderings and construction milestones expected as the design-build team locks in floor plans and lab layouts. For official timelines, documents and updates, UW Facilities maintains a public project page, and the chemistry department continues to post periodic notes from the chair on funding developments and schedule changes as the 2029 opening date approaches.
