Abstract
In the article, I reflect on current urbanization processes by addressing the relationship between middle sectors, self-build of houses and non-conventional architectures. Since the socioeconomic crisis generated by the Covid-19 pandemic, the Paseo Costanero Sur in Mar del Plata presents an exponential growth of dispersed self-builders carried out by middle sectors. At the same time, this phenomenon develops in a context in which there has been a resignification of the use of land as construction materials and of containers as a housing structure. As a result of field work carried out from a qualitative perspective, the article problematizes this trend, the factors that drive it and the type of city that is produced.
