The Kimmel Center is a 10-story structure centrally located on Washington Square South and La Guardia Place. The top two floors are glass enclosed, allowing for sweeping views of Washington Square and lower Manhattan. The student center includes a 860-seat auditorium, 150-seat performance studio, rehearsal rooms for music and lectures, student club lounges, dining rooms, and offices. The top floor of the building features a special events hall with seating for 400. The selection of building materials for the Kimmel Center was based upon the predominant masonry materials around the square: brick and limestone. The main body of the building includes Vetter limestone from Minnesota with some details in buff Indiana limestone. Glass is used as both vision lite in the windows as well as a contemporary enclosure material at the entrances and at the roof, juxtaposed with the more stately mass of the building. The Kimmel Center was designed for continual student use and is open 18 hours a day. The glass enclosed staircase on the west side connecting the various club and meeting facilities were designed to encourage its use and increase the interaction among the students. The Skirball Center is the largest performing arts facility south of 42nd Street, and is the premier venue for the presentation of cultural and performing arts events for NYU and lower Manhattan. Outfitted with state-of-the-art light, sound, and projection equipment, it provides a professional- level facility for concerts, film screenings, and theatrical productions showcasing the talents of NYU undergraduates and graduates. Since opening in 2003, the Center has been an educational and community building resource, providing NYU's first large-scale, professional performance space on campus. Recently, the Kimmel Center hosted Secretary of State John Kerry’s speech on foreign policy.
