The contribution shows the results of a research aiming to the chrono-typological definition of earthen building situated in the South of Sardinia, specifically in Quartu Sant’Elena, Villamassargia, Serramanna and Pirri. Indeed, there is no systematic and scientifically based catalogue of the traditional solutions used by the Sardinia builders for the realization of earthen walling, with great detriment for their conservation, especially with reference to the so called ‘minor building’, just for its non-identification. Considering this lack, the investigation aims to date masonries, using chrono-typological criteria, based on: - the examination of the printed sources concerning building materials and of archive sources; - the realisation, through metric and photographic surveys, of drawings highlighting the constructive peculiarities of the masonries analysed (metrical, materical, morphological); - the identification of the chrono-typological models identified; - the definition of chronological series of the structural solutions. Specifically, through the interpretation of local techniques, it is possible to study in detail the traditional building practices. The aim of this research, in operative sense, is double, i.e.: 1. to arrive to a correct definition of the restoration project, really respectful of the essence of the building, as well as respectful of compatibility and reversibility criteria; 2. to promote the permanence of the use of earth, as we know very vulnerable and easily degradable, but representing a sustainable solution, exploring new rules for the contemporary project. Besides, one believe that the deep knowledge of constructive characteristics, by a structural, chemical and physical point of view, is the only preliminary remark to plan a conservation project, in the respect of cultural, materical and figurative consistence of architectural heritage.

Abstract
The contribution shows the results of a research aiming to the chrono-typological definition of earthen building situated in the South of Sardinia, specifically in Quartu Sant’Elena, Villamassargia, Serramanna and Pirri. Indeed, there is no systematic and scientifically based catalogue of the traditional solutions used by the Sardinia builders for the realization of earthen walling, with great detriment for their conservation, especially with reference to the so called ‘minor building’, just for its non-identification. Considering this lack, the investigation aims to date masonries, using chrono-typological criteria, based on: - the examination of the printed sources concerning building materials and of archive sources; - the realisation, through metric and photographic surveys, of drawings highlighting the constructive peculiarities of the masonries analysed (metrical, materical, morphological); - the identification of the chrono-typological models identified; - the definition of chronological series of the structural solutions. Specifically, through the interpretation of local techniques, it is possible to study in detail the traditional building practices. The aim of this research, in operative sense, is double, i.e.: 1. to arrive to a correct definition of the restoration project, really respectful of the essence of the building, as well as respectful of compatibility and reversibility criteria; 2. to promote the permanence of the use of earth, as we know very vulnerable and easily degradable, but representing a sustainable solution, exploring new rules for the contemporary project. Besides, one believe that the deep knowledge of constructive characteristics, by a structural, chemical and physical point of view, is the only preliminary remark to plan a conservation project, in the respect of cultural, materical and figurative consistence of architectural heritage.
