6011 Friends Avenue was built in 1922. It was home to Joseph W. Plummer, as listed in the 1924 Whittier City Rivera and Suburban Directory. Originally from Illinois, Joseph lived with his wife Rhonda M., who was from Ohio.
This residence is significant as an excellent example of Mission Revival architectural style. At a time when new residents were immigrating in large numbers to Whittier from throughout the United States, increased interest in California history contributed to emergence of the Mission Revival movement, which encompassed restoration of extant buildings from Spanish and Mexican periods of rule, including missions and adobe houses, in addition to development of new buildings with exterior designs loosely referencing these early California buildings.
