The next year in 1930, the Annex and Little Palestra were built to provide additional classroom space as well as an indoor gymnasium and swimming instruction. After World War II, additional expansion was made with the acquisition of the Mack and Farr buildings, which were located across Seventeenth Street on the South Side of Linden. These were two late Nineteenth Century Victorian homes. The Mack building was used for Business Education classes, while the Farr building taught various home economic classes. The Hunsicker Building, located in the 300 Block of North Sixth Street, was used for Honors classes; the Nineteenth Street machine-welding shop was leased by the ASD for Industrial Arts training.
