In 1888, Girard College made plans for a new school building that could accommodate about 200 students in the middle school grades. Building #10 was constructed in 1889 and opened in 1890 for school and classroom use. James H. Windrim, a Girard College alumnus and the appointed architect for the Board of Directors of City Trusts, designed the building in the Gothic revival style he previously used for the first Chapel and Buildings #7, #8, and #9. Located behind the Chapel, Building #10 was memorable for its distinctive castle-like turrets. The 3-story white marble building was comprised of two wings connected by a corridor. The basement had playrooms that could be used during inclement weather. The first and second floors consisted of eight classrooms each. The third floor had a large auditorium, where entertainment, guest speakers, and exhibitions were hosted for students. This new school building allowed Girard College to increase its student population to over 1,500 students. Although the organization of grades in the middle school often fluctuated and varied throughout the 19th and 20th centuries, it typically consisted of the 4th-6th grades, which are today considered to be upper elementary school grades. The 7th and 8th grades were included in the middle school during certain time periods as well.

The completion of Building #10 was half funded by the bequest of Lawrence Todd, an Illinois farmer who visited Girard College in the early years of its operation and left his fortune to the school in his will. His original bequest of roughly $20,000 had increased to nearly $77,000 by 1890 through investments. The rest of the approximately $144,000 for construction and furniture costs was financed by Stephen Girard’s estate. A brass plaque to memorialize Todd was mounted at the building’s east entrance after it opened. The school even considered naming Building #10 as the Todd Building in honor of the late benefactor. Later on in 1922, the Board of Directors decided against using outside donations for campus expenses that did not directly benefit students. The $77,000 used from the Todd bequest was repaid to the fund, which would instead be used to grant college scholarships to Girard College graduates. 

When all of the numbered buildings on campus officially received names in 1927, Building #10 was renamed as the Middle School Building. In 1928, the Middle School and High School Buildings were connected by a newly built annex, which contained a small gym and pool. The auditorium on the third floor was replaced in 1937 by a “library-laboratory”, which supplied reading materials for the elementary and middle schools as well as AV equipment for their teachers. It was also used for class instruction, student research, and leisurely reading. In 1959, all 1st-3rd grade classes were moved into the Middle School Building so that the Junior School Building could be solely used as a dormitory for the elementary and middle schools. In 1975, the Middle School Building was demolished and later replaced with a parking lot.
