In 1917 the Torrance School Main Building opened, housing the elementary and high school.[2] In 1923 this Torrance Elementary School building opened on the southern side of the campus, and the original Torrance School Main Building was converted into a high school only.[2] A new elementary school building was built off campus in 1963, and this one was annexed to the high school and renamed the Torrance High School Annex or Annex building.[2]
The building, built over 1923 to 1925, was designed in the Renaissance Revival style.[2] It is connected to the rest of the campus by a long curving and center−pillared Modernistarcade.
Torrance elementary schools were in the Los Angeles City School District until 1947, when they became a part of a new school district, renamed Torrance Unified School District in 1948. In 1947 the Los Angeles City School District removed the furniture from Torrance schools.[3]
