Current research on house form and meaning highlights a growing discor-dance between users' requirements and housing standards in western socie-ties. Among the major causes of this discordance particular emphasis is puton the dwelling designers' and planners' neglecting of individual differencesin dwelling habits (Lawrence, 1987). Individual differences seem current-ly to be magnified by socio-demographical changes in household compositionand by changes in systems of transmission of cultural models among differ-ent social worlds. A growing amount of theoretical and empirical studiesargue for a central role of household structure and socio-cultural variablesin affecting the meaning of home. However, little empirical evidence is yet available about the way in which different groups of people actually organizeand use their domestic space.In order to explore the way different households spatially realize daily liv-ing activities in an urban context, a questionnaire survey was carried out inRome. The survey sampled 500 households representative of the city popu-lation with respect to housing location and number of components.The theoretical assumption underlying this study is that the main dimensionin the ordering of domestic space is the socialization-privacy dimension andthat changes in meaning and use of the dwelling will affect primarily thisdimension (Altman & Chemers, 1980; Giuliani, 1987).Two dwelling activities -eating and sleeping- were analyzed in terms ofspatial, social and temporal qualities in order to individuate similarities anddifferences among households in patterns of socialization and privacy (Wer-ner, 1987). The spatial quality of eating as well as variations in the degreeof intimacy among participants (family, friends and guests) and the tem-poral aspects (daily cycle, holidays) were analyzed to define different pat-terns of socialization. The features of sleeping space of the household mem-bers (shared vs individual, primary destination of the room) were analyzedin order to define different patterns of privacy. The relationship betweenactual behaviors and utilization of an hypothetical extra room was also ex-amined in order to establish a hierarcy of spatial requirements. Socio-demographical characteristics of the inhabitants as well as physical prop-erties of the dwellings were considered.Multivariate statistical procedures were applied to the data to unify andsummarize in one comprehensive framework the several interactions un-derlying the observed data. More specifically, correspondence analysis andcluster analysis were selected in order to describe individual differences.
