Tuscaloosa Institute purchased and built a home at 1008 21st Avenue, now the site of the Stillman Heritage House.
As the institute’s campus expanded, so did its offerings and its student body. An academic department--the beginning of what would develop into a standard high school--had been added in 1893 to supplement the seminary program, and in 1899 Stillman added additional courses and opened its doors to female day students.
Not until 1922, however, would the school become officially co-educational. In that year, a women’s dormitory was erected on campus and named in honor of Hallie Paxon Winsborough, a central figure in the Presbyterian movement to provide training for young black women.
