This article examines the potential utility of space syntax theory (Hillier & Hanson, 1984; Zimring & Gross, 1991; Peponis, Zimring & Choi, 1990) to study the relations among residential crowding, design elements, and human well being. Dormitory rooms with greater sunlight are perceived as less crowded than same-sized rooms with less natural light (Schiffenbauer, Brown, Perry, Shulack & Zanzola (1977). Baum and Davis (1980) modified a long-corridor dormitory to create a smaller subunit of rooms. This change significantly reduced perceived crowding. Self-reports of excessive, unwanted social interaction dropped; more pro-social behaviors were observed; and laboratory experiments outside of the dorm indicated more social engagement and less withdrawal.
