Holmdel High School is physically connected to the William R. Satz Middle School and is notable for its unusual hexagonal architecture. The oldest part of the building structure is the English/Humanities Hallway, with classroom numbers running in the 100s. The main part was completed in 1973, including the Commons, the 400s, the 500s, the Library, the Gym, the Complex Auditorium, and the TV Studio. The 400s (and 500s on the second floor) are eccentrically designed in a circular fashion, with both ends reaching the Commons. They surround the Library and Conference area. In addition to classrooms, the 400s wing also houses the Humanities Department Office, "The Sting" newspaper office, and "Creation" yearbook office.
