Introduction Boundaries exist everywhere; there are boundaries throughout our social environment, and houses are no exception. It is widely accepted that house plans and the use of space reflect underlying sociocultural values and associated psychological needs, for the house is not only a physical space in which we shelter but also a space where social interactions take place (for example, Mumford, 1970; Saunders, 1990). As cultural values and norms vary, so do psychological needs (see, for example, Markus and Kitayama, 1991), and the configuration of houses changes accordingly. Culture' is a relatively organised system of shared meanings (Geertz, 1973), and the meaning of social space is part of that system. It is not a simplistic linear causal relationship, in which culture produces house form. There are many elements of culture, which are interwoven and mutually reinforcing (for example, ecological and environmental context, values, notions of personhood, social structure, ontological beliefs, and construction of gender). House form (that is, the shape, the boundaries, and the organisation of the house) is one of these elements. It reinforces values and is enabled by them. Elements of culture are maintained because they work for people; and they work differently in different cultures (and subcultures). (1) The basic boundaries in the house are, therefore, expressions of culturally recognised norms which regulate human behaviour. Seen this way, boundaries function at three distinct but related levels: physical or spatial, sociocultural and psychological. The boundaries at the physical, spatial level are concrete manifestations of social classifications, and social classifications are internalised by people and experienced phenomenologically. To clarify, using a simple but commonplace example: a bar (or pub) usually has an entrance. This is placed on a physical, spatial boundary which marks the area classified
