In 1888, they purchased a larger building at Franklin and Ellis for $10 in gold coin. They stayed there until the 1906 Earthquake when the building was heavily damaged. Renting another Victorian at the corner of Washington and Octavia, they were one of the first institutions to reopen after the earthquake. In 1909, the school purchased the Van Arsdale house on Jackson Street where the school remained until 1939. In June 1939, Maud Lee Flood donated the home she had shared with her deceased husband at 2222 Broadway. During WWII, boys were allowed to join the lower school. By 1948 they needed more room to expand, they courted a deal to purchase the Grant house for $150,000, well below market value. The lower school, grades 1-8 split to the new location, while the upper school remained at the Flood Mansion. But what to do with the boys? In 1956, they purchased the Hammond House for $165,000 to open Stuart Hall for Boys.
