I often wonder whether, in a few years' time, these places and these countries of Sardinia will remain as they are, as I am looking at them at the moment. The research is presented as a report of a process of observation and behavioural analysis of historical building fabrics; tells the phenomenology of the historical urban transformations of some areas of the island. The study cases in fact have as their common denominator the theme of depopulation, morphotypology hybridization and "unfinished". We want to highlight how the role of time, of cultural stratifications, of abandonment, transform the landscape. From a photographic commission assigned from Sardarch, society spin-off of the Faculty of Architecture of Cagliari, a topographical and social survey is born and realized, which has been discussing the problems of depopulating countries for several years. The assignment had no precise rules, through a personal interpretation of the spaces a mapping was born almost in the form of a spaces matrix that presented themselves to my eyes. The reference scenario takes place in the inner areas of the island and, in particular in certain specific countries, affected by imminent changes of urban character. The state of the events has led the project to take place in the midst of a pandemic, a situation that has called for a new assessment of the concept of living in a place, home and isolation. The result is a morpho-typological catalogue that illustrates the evolution of the living characters of these places. In this way it is possible to compare and measure the evolutionary processes of the settlements. Using an almost iconographic language I highlighted the formal characteristics of a habitat and therefore of a society that has lived for a long time the complex relationship with the landscape, translating it into certain forms of use and territorial figures. The method used for photographic production is recognized through the repetition and identification of those temporal and behavioral characters of the individual places studied. The aim is to provide documentation that monitors the changes in these fragile places and the meaning that society will attribute, in the future, to the term dwelling.
