The Central Institute for the Deaf, an institution combining oral education for deaf children, scientific research, clinical services, and graduate education, has expanded their urban St. Louis campus. The new two-story, 42,000-sf classroom building resembles the original 1928 Mediterranean-style building. The school has a full-sized gym, family center, music, art and discovery rooms, and a library/computer lab suite. Each classroom meets rigid acoustical requirements for background noise. A 71,000-sf research facility features cellular and molecular biology laboratories and core facilities, a conference center, and a central cafeteria. The new school and research center is designed by St. Louis architects Mackey Mitchell Associates.
