In 1902, Phoebe A. Hearst built a 3-story brick building at 560 Union Street for teacher training and kindergarten classes, and to house the Golden Gate Kindergarten Association’s offices.

After the turn of the century the Golden Gate Kindergarten Association’s schools began to consolidate to better serve the changing communities that emerged as San Francisco rebuilt itself following the 1906 earthquake and fire. By 1906, the Golden Gate Kindergarten Association had 26 schools, seven of which were destroyed by the earthquake and fire. Temporary classrooms were quickly found to replace these schools, including barracks in the Presidio and Golden Gate Park, and tents erected in Golden Gate Park and Washington Square.
