Gregory House
Karl D. Gregory Cooperative House at 1617 Washtenaw was originally built in 1909 for the Tau Gamma Nu fraternity and was purchased by the ICC in 1995. Gregory House is the only house in the organization that is expressly substance free. No tobacco, alcohol, or illicit drugs are allowed on the property.
Karl D. Gregory is an activist, professor, and an alumnus of Nakamura House. Gregory donated $20,000 to the ICC, which served as a downpayment to acquire a new coop. In thanks, the house was named in his honor.
