A quartet of communities named for the cardinal virtues of Justice (Iustitia), 智慧(Prudentia), Self Control (镇静剂), and Strength (企图), the 房子 System is a key facilitator of fellowship on the 山核桃校园. Upon attending, each individual finds a home in one of the four 房子s. 房子 members seek to know, 庆祝, 服务, 彼此相爱, fostering a positive culture that stands apart. 房子 also provides educational leadership and administrative opportunities for students through the 房子 Leadership Team, a body of elected student officials and a faculty Head of 房子 who shepherd their 房子 throughout the year. Through the 房子 program, Covenant creates a community that encourages students to live out the 房子 motto: 为别人，为基督.
