Designed by Wilson Brothers, architects and engineers of Philadelphia, PA, the brick exterior facades of Williams Hall are enriched with terra cotta Gothic ornamentation. Above the large Romanesque entrance arch are terra cotta medallions, above, with reliefs of three noted American scientists of the day, Louis Agassiz, Samuel F. B. Morse and Joseph Henry.
Gargoyles defend the building at the bases of the gable parapets.
