"The influence of the juridical and architectural form of housing and more particularly of the dwelling-apace on behaviours of appropriation is meaning ful only in relation to the social components of the resident population. These results are arrived at by studies made in general on "social" (i.e. government owned, low-rent) housing, or on housing recently built and financed by various subsidies. Besides the practices in the lodging itself, it has been observed that the main differences in the inhabitants' speeches referring to an estimate of the general quality of their lodgings dealt with the exterior spaces and rela tionships with neighbours on the one hand and the general image of their buil ding on the other hand. Thus in the architectural field the innovation problem appears as an indicator of the ideological distance between conceptors and users. Therefore it has been noted that the morphological differences of innovating housing modified the concrete but shove all the symbolical appropriation only through an identification with the innovating conception upheld by the Establishment or the conceptors."
