More than ever, Americans are experiencing the negative effects of infrequent social interaction and thinning social networks. However, the ‘loneliness epidemic’ is only one part of a greater issue facing the nation: the steady decline of community within America. The rise of social disconnection among Americans is further evidence that today’s communities can no longer be considered socially sustainable. Beginning with a literature review of social disconnection and social capital theory, this thesis will analyze social factors’ effect on individual and community health. Next, an analysis of alternative community models will be used to identify architectural strategies for promoting social interaction. Using the factors identified in both the literature review and precedent studies, a set of design guidelines for community development will be created. These guidelines for development will then be used to design a new urban community in the redeveloping business district in Wheaton, Maryland
