Cognitive Safeguard of the Tunisian Middle Class Dwellings Architecture

Our study proposes a cognitive and virtual safeguard, of architecture of tunisian middle class dwellings at precolonial period. The Tunisian domestic architecture included two main forms; the urban dwellings intramural and the suburban dwellings extramural, only one form was subject of work and scientific research; the intramural houses. Through this study we try to understand and to know the particularities of the Tunisian suburban domestic architecture for better conserve our heritage which is lost from day to day.The morphological and structural analysis of these buildings allowed us to study their logic of internal organization, their evolution and we are trying to extract the identity system.
