From 1894 to 1905, the Tewksbury campus saw extensive new construction, including several buildings designed by Boston architect John A. Fox—the Old Administration Building (1894), the Male Asylum (1901), the Women's Asylum (1903). During that period, the Old Superintendent's House (1894), the chapel (1896), the Main Gate (1900), the Southgate Men's Building (1905), and Male Officers Dormitory (1905) were also added to Tewksbury, along with several farm and support buildings. Two other hospital buildings at Tewksbury were designed by the Boston firm of Hartwell and Richardson.
