From urban planning instruments to produced urban forms: Analysis of the eastern extension of Oran (Algeria)

Abstract

This article starts from an observation, that of an urban and architectural production in the eastern periphery of Oran which is strongly criticized. In this research, we examine the choices that governed the urban development of Oran, favoring the production of large complexes. We highlight the excesses that result from the quantitative option chosen by public authorities to the detriment of urban form. Thus, the examination of the process of urban development as well as the urban forms produced in the eastern extension of Oran constitute the problem addressed in this article. Based on morphological analysis, we were interested in the components of urban space. Town planning documents, city maps, aerial images, photographs, on-site observation were used to carry out our research work.

Even if we admit that these town planning documents are necessary for planning, they remain largely
