As enrollment increased, expansion became necessary. In 1926, a second Collegiate Gothic quadrangle was added to the north of Thomson College. Also by Cram, this quad was known as North Court. Finally, a third section was built in 1963 by the firm of Ballard, Todd and Snibbe. Although in a modernist style, these quads, known as the Procter and Compton Quadrangles, were constructed in the same stone as the original Graduate College.
