CSU San Marcos University Student Union

Serving as the gateway building for the northern entrance of CSU San Marcos, the University Student Union is a hub of student life and recreation that is designed to support the campus as it grows.

The USU's central outdoor amphitheater functions as a hub with connections to student lounges, study spaces, retail, several cafés, and exhibit areas. A dining court providing a variety of indoor and outdoor seating offers students a range of cuisines all day. A conference facility organized around a flexible, multi-purpose ballroom that supports the Union’s large-scale events. Directly above the ballroom is a rooftop events terrace providing vistas north and south of the San Marcos hills. Drought tolerant plantings and a green roof are key sustainability components of the USU's terrace and create an inviting outdoor space for students to gather and relax. The collaborative design/build project was completed in Spring 2014.
