The campus has undergone extensive massive upgrades since the mid-1990s. Baines House and the Thurston C. Chase Learning Center have been renovated. The Schwab Family Pool, and the McFadden Rink at Alfond Arena and a new track and field facility have been built in the late 1990s. Two new dormitories, Kravis House and Mayer House, were completed in the early 2000s. In 2007, a major renovation was undertaken on Flagler House, Halsted House, and Taylor House. The Learning Center was also extensively renovated at that time. During the summer of 2010, the Sports Center was renovated, adding two new international squash courts, bringing the total to six, a new student lounge and student fitness room, and a 50-kilowatt solar panel system on the roof of the gym.
