Santa Rosa Junior College Mahoney Library

Petaluma, CA

Santa Rosa Junior College’s Herold Mahoney Library claims pride of place as the centerpiece building on a new eastern quadrangle in the Petaluma campus.

The 37,000 square foot library is a magnet for commuter students looking for study spaces and research support.


The Community Reading Room serves as a venue for expanded cultural and civic events, which bring community members in contact with SRJC’s educational opportunities. Flexible furnishings allow the room to be rearranged easily by users.


Tall glass curtain walls open to the east and capture the view across a new campus green to Sonoma Mountain. Flanking the 25-foot tall glass wall, a day-lit quiet study area on the second floor overlooks ground floor computer study zones. The two-story volume glows at night and is a beacon to the surrounding residential neighborhood.


Warm wood tones and natural materials add to the relaxed and welcoming atmosphere for this satellite campus set in a rural/suburban region of Southern Sonoma County. Four light monitors recall architectural forms found in nearby agricultural buildings, and bring daylight deep into the second floor space.
