It was originally housed at the former site of Larson College (now Quinnipiac University) at 1450 Whitney Avenue in Hamden (now a privately owned elder care facility called Atria Larson Place).

In 1988, Hamden left the project, and the Co-op moved to the former St. John the Baptist School at 800 Dixwell Avenue in New Haven.

There they were joined by the Center for Theater Techniques in Education (CTTE) which incorporated the arts into the academic curriculum already offered.

In 1990, the Co-op moved to the former St. Mary's High School building at 444 Orange Street in New Haven.

[1] The new building, designed by architect César Pelli, is a 60,000-square-foot (5,600 m2), $73 million state-of-the-art facility which includes a television studio, 350-seat theater with fly loft, black box theater, chorus and music rooms, 4 fully equipped computer labs, and academic facilities.
