Building History

A color image of the Gilbert Hall Addition.


Purpose-built in 1980 to provide space for Chemistry lab instruction, the Gilbert Addition was recommended in 1975 by Oregon State Board of Education, in part due to safety concerns. In 1977, students signed a petition to save the small park and 11 cedar trees on the proposed site; their request to select an alternate site was denied.  Delivery delays,a labor dispute, and a failed inspection by the Department of Commerce (who said the sink-traps in the lab benches were unsafe) further delayed the completion of the building. Though plans for a name change were made at its completion in 1980, as of 2022 the Gilbert Addition has yet to be renamed.
