Tecnologie costruttive “appropriate ed appropriabili”: tipicità dell’architettura informale

Typicality in architecture is an issue closely linked to the construction. A landscape is defined as "typical" when it is possible to acknowledge some essential features, concerning the urban structure, the building types, materials or colour. There is a reality that, although without structured rules, reveals however a typical landscape, defining the so-called "informal architecture". Slums, favelas, earthen villages. These are places at the margins of the city in the South of the World, where people live in overcrowded conditions, in total absence of services. In these contexts, the intervention of architects lacks and any urban plan or project order is considered unnecessary. Only what is strictly required is constructed and the so-called "spontaneous architecture" is generated. However a kind of homogeneity of architectural language is still discernible. Relatively to production systems and construction, an interesting research was carried by the team named “Casapartes” that has distinguished two different types of technologies: "appropriate and appropriable".
