Completed in 2009, the former A-Wing Lecture Hall is now the Elizabeth B. Alton Auditorium: a 6,000-sf gut renovation/adaptive reuse of an existing one-floor auditorium space. It has been transformed into a 276-seat, tiered lecture hall and performing arts center. It features a high-performance audio and video system to accommodate live performances, as well as lectures and seminars. The project utilized the existing shell and opened it up at the primary viewing wall to introduce a two-story window wall that provides views to the nearby forest and lake. The main entrance to the space was moved from the first floor to the second floor; a small foot bridge was constructed for access from the main gallery.
