It then goes on to highlight the inadequcy of post colonial housing solutions in Algeria and to look into two important aspects of this traditional housing typology; its socio-cultural relevance and environmental performance. The analysis is carried out using both secondary research in the form of three examples from the literature. and primary research carried out as field work in the form of temperature measurements inside a house, during the hot season, in Boussaada (Algeria).
