Another group of residences, known as the Village, is located in the northwest corner of Danforth Campus. Only open to upperclassmen and January Scholars, the North Side consists of Millbrook Apartments, The Village, Village East on-campus apartments, and all fraternity houses except the Zeta Beta Tau house, which is off campus and located just northwest of the South 40. Sororities at Washington University do not have houses by their own accord. The Village is a group of residences where students who have similar interests or academic goals apply as small groups of 4 to 24, known as BLOCs, to live together in clustered suites along with non-BLOCs. Like the South 40, the residences around the Village also surround a recreational lawn.
