Howard Longshore Stadium is where the school's football team has its games and where the marching band, track and field, and cross country teams practice. It includes a running track which circumscribes it, as well as concrete bleachers on each side. It was resurfaced with FieldTurf after the 2012 Super Bowl. Both the Stadium and Stuart Hall were originally constructed during the Great Depression using New Deal funds.
Usually considered to be the main classroom building and having about half the classroom space, Treadwell Hall was constructed in 1921 and was the second building addition to the new school, and the only one still standing. The original officer's East Residence was demolished in 1929 after two wings were added to the building in 1928. Also built in 1922, Lone Hall was originally known as the Power and Shop Building. It housed the school's power plant and vocational classes.
When it was built in the 1950s, Morgan Hall was considered the "new" shop building, because it took over some of the duty from Lone Hall.
Built in 1965, the music hall houses the kitchen and cafeteria as well as the music department and the commercial foods track for CTM. Constructed in 1977, this auditorium is the school's main auditorium and is where the school's plays and special classes, such as set design, are held. The West Gym was constructed in 1929 and known as the Boys' Gym, with the Girls' Gym being in Lone Hall. It was renovated in the 1970s as the new East Gym/Natatorium was being built next to it. These facilities are mainly used for swimming, volleyball, conditioning, and basketball. They also hold physical education classes during the day.
The media center houses the school's library, computer labs, resource rooms, and a bookstore. There is also an outdoor amphitheater adjacent to the outside of the building.
