House design has reflexive power, representing our lifestyles and associated values. This paper explores meanings attached to house design through the analysis of people's ritualised activities and use of domestic space by using the notion of 'lifestyles'. Lifestyles are 'patterns of activities' - i.e. patterns of social relations, consumption and culture (Abercrombie et al. 1984). Lifestyles are sets of shared values and practices that make sense in particular contexts, differentiating people and explaining what they do, why they do it, and what doing it means to them. (Chaney 1996). Indeed, how we lead our everyday life is a key to understanding the meaning that we attach to our living space. As Douglas (1966) puts it, rituals are an attempt to maintain a particular culture or a particular underlying assumption by performing visibly. The use of domestic space and the layout of a house, therefore, reflect our underlying values, norms and ideologies (Clark 1973; Mumford 1970; Ozaki 1999, 2001, 2002 forthcoming).
