The Portland Sanitarium Nurses' Quarters was originally built in 1893 for the Seventh-Day Adventist church and was intended to be a prep-school for medical missionaries.

 

The existing 4-story building underwent construction to add 62 new apartment units and 14 sleeping units added, and complete seismic retrofit for the entire building.

​

The project consisted of large amounts of saw cutting slab on grade and excavations for new utilities and new foundations.​
