These halls are referred to as the '64 Halls (construction began in 1964). Renovated in 1994, these halls have mostly single rooms with an open lounge on each floor. Designed for privacy, each floor is constructed with two u-shaped sections, connected by a lounge area. All of the halls are coed; however, Porter and Whitney have single-sex floors. Blaisdell, Bushnell and Peet are coed by room. The College Health and Counseling Centers are located on the first floor of Porter Hall. The quiet floor and the alcohol-free floors are located in Bushnell Hall. A gender neutral floor is located in Blaisdell Hall.
