 For the day-to-day life of the schools, the major change was that Country Day sent its older boys to Detroit University School and became a school for girls.In 1954, the Country Day building was sold to the Grosse Pointe public schools and the girls joined the boys on the Cook Road campus, merging the schools to make Grosse Pointe University School.Minoru Yamasaki was commissioned to design a lower school, a middle school, and other facilities, such as a new gymnasium, an auditorium, a library, and fine arts rooms, to complement the two-story brick building erected in 1928.
