Even-numbered floors overlook the lounge and have a spiral staircase leading to the floor below. South and West Towers are equipped with the House washer and dryers, while North shares the Sandburg Laundry Center , located in NG 2.
Most Houses are coed, meaning that males live on one floor and females live on the other.
Each of the towers contains three elevators that face the hallway opposite the lounge on each floor. One of these elevators stops on every floor. The other two elevators go only to the odd-numbered floors.
