"This survey is based on a representative sample of 2 427 families sys-tematically selected out of a population of 5 582 who purchased a new single-family home or had one built in 1978 in Alsace (Eastern France). After stressing the links between the aspiration for this kind of housing and the characteristics of the previously occupied homes (qua-lities, equipment, location etc...) and after outlining the socio-economic profile of the buyers, the author highlights the importance of the detached house ideology in France. The dimensions of the aspi-ration for this kind of housing are then described, leading to an analysis of toe conflicts and congruences between the ownership and the appropriation of the home, and between the economic motivations ("protecting one's savings") and the psychological ones ("feeling at home"). The dimensions "living in a home one has personally chosen", "making one's own home" and "owning a property to hand down to one's heirs" are contrasted with those of the financial and personal com-mitment on the one hand, and of sociability on the other hand. As a conclusion the author shows that the population of single-family-home buyers belongs to the social category that has constantly, in the past hundred years, made its own the detached house ideology and that nowadays equates the ownership of such a house with the achieve-ment of social dignity and status."
