The tree-lined campus is bordered on the north by Buxton Park Arboretum. Simpson blends tradition with modernity which is reflected in the architecture on campus. Many of the buildings have been renovated in keeping with their historic past, and new buildings blend the traditional look of the campus with an energetic dimension. The theater building, an example of the Brutalist architecture that dominated American campus construction in the 1970s, was renovated and added on to in 2010-11, softening its features, but is a notable exception. The renovation and addition to the theater building is the first of many construction projects that Simpson has planned for the next five years.
