With its Flemish gable ends, the school is a fine example of Dutch Colonial Revival-style architecture.
 The original building contained ten classrooms, lab and recitation space, and a 500-seat assembly hall.

A contemporaneous account describes the original structure:
The Central School in Iron River is an imposing and modern structure of two stories and a basement.... It is lighted with electricity and heated with steam and hot air, the air being forced into the rooms by means of a large fan.
 It also includes among its improvements an electric vacuum cleaning plant in the basement, which is probably the only one in operation in an Upper Peninsula school building.

The 1910-11 wings added more classrooms, as well as a music studio, commercial room, stenographic room, dark room, and offices for school district personnel.
