This presentation will discuss a collaborative study of changing household compositions and dwelling redesign in New York City public housing. More specifically, the research examined how a redesign of existing apartment units might better meet changing household needs. The intention of the study was to examine the way that residents furnish and use typical public housing apartments, so that future modernization work might be more responsive to resident needs. It looked at different types of apartment configurations in three public housing developments. In-depth interviews were conducted with 67 resident households about their patterns of daily life activities and use of the space. Apartment use was also recorded on annotated floor plans which reflected how residents furnished them. Additionally, photographs were used to both document the space and to investigate resident feelings about it.
