About our building

  • Old Timberline
    Old Timberline Campus (1970-2010)

    New Campus
    Current Timberline Campus (2010-current)

    Timberline High School opened in 1970 as an open-concept school. At the time, this was a popular approach to the design of new high schools. Instead of classrooms, the school was divided into “pods,” and students attended classes according to modular scheduling of large classes in lecture halls and small group classes in open areas. They also had unscheduled time each day for self-directed learning.

    That approach to teaching and learning soon evolved into a more traditional model. Teachers began to create makeshift classrooms using bookcases, cabinets and any other material on hand, and the schedule was changed to six class periods every day.

    In 2006, construction of the “new Timberline” began. The school underwent a major $59.7 million modernization and addition project, and the main building was moved a few hundred yards from what is now the student parking lot. The gyms, pool, theatre, fine arts classrooms and auto shop areas were also remodeled. The new building has three floors of classrooms and is organized around the Commons, library, administrative offices and food service. The 197,728 square foot building, including 81 instructional spaces, plus 8 portable classrooms serve ninth through twelfth grade.
