Parrington Hall was build 6 years after Denny hall making it apart of the original campus (see map below). The building was finished in 1902 and was called the Science Hall. A contract, now within University of Washington’s Special Collections, shows that the owner of the land at the time, Auton Bereus Witnesseth, agreed to let the University of Washington build the Science hall on his land. The document was very hard for me to understand but I interpreted that Witnesseth was going to pay for the building and if he could not the land would go to the University.

Both the department of Botany and department of Electrical Engineering started in this building and eventually moved to other buildings The Department of Electrical Engineering moved there operations in 1910 and the Department of Botany moved later in 1930’s. Now the building is a center for Daniel J. Evans School of public police and governance. In 1931 the building was remodeled by John Graham Architect. They installed a new sewer, re-shingled the roof, waterproofed the building and many more. I have read other resources that state it was remolded another time but could not find any documentation of the remodel.
