Initially intended to increase capacity for the Law Library collection, the Berkeley Law project evolved into a major, phased, adaptive reuse and addition that addressed numerous deficiencies in the existing complex. The first major renovation project consolidated 12,000-square-feet of student groups and various law journal spaces into one unifying area — the lower west level — and converted the former student space into greatly needed new faculty offices. The new South Addition houses highly efficient library stack space and a combination of reading rooms, seminar spaces, computer labs, library staff offices, and collection services in two light-filled underground levels. Large skylights and open stairways serve as an inviting environment in the above-grade level, complete with a large classroom flanked by a café for interactive study and social gathering. A second level roof-deck garden above the addition provides plenty of outdoor seating with a connection to the library’s main reading room and a footbridge to the Steinhart Courtyard. The new addition is designed to achieve LEED® Gold certification.
