According to a student publication of the time, Dickinson was known for its "frequent oscillations" and required structural reinforcement, and in 1877, the building was extensively overhauled. These repairs were carried out under the direction of Edward D. Lindsey, the curator of Grounds and Buildings, who also altered the roof to harmonize with more colorful High Victorian Gothic Chancellor Green Library (built 1873) and the John C. Green School of Science (built 1877).

Lindsey added an ornate new entrance to the north facade, expanded the third floor, introduced crockets and other exterior details, and added a large central tower.
