[3] Overcrowding at the former site of Hixson High resulted in plans being made, beginning in 1964, for a new school facility.

A two-story wing to the school for the mathematics, music and foreign language departments was added in 1986.

Ground was broken in 1992 for another addition which includes classrooms, chemistry laboratories, home economics laboratories, a student publication room, teacher work areas, locker space, and an expanded music department.

The tennis teams train and play home matches at a new on-campus facility built in 2019.

[citation needed] Hixson's gymnasium, the school's oldest sports facility (original to the building opened in 1966), is used by the basketball, wrestling and volleyball teams.
