During the 20 ^th Century, rural landscapes underwent rapid transformations as a result – among many factors – of mechanization of agriculture and the introduction of new means of transportation: rural territories, indeed, started being signed by new railway lines and agro-industrial facilities, necessary for the storage and distribution of an increasing amount of agricultural products. This is particularly evident in Europe for the landscapes of grain production, as well as in North and South America. A recent research by the author about the grain silos built in Italy under the Fascist regime set the basis for an in-depth analysis of grain production landscapes in Italy during the first half of the 20 ^th century, also in comparison with the European and American contexts. To this aim, survey and representation of landscape settings become crucial, for the interpretation assessment of significance of these still underestimated cultural landscapes. Therefore, the aim of this contribution is to propose a methodology for the knowledge and preservation of 20 ^th Century grain landscapes – and their built heritage – choosing as case studies the grain silos built in Tuscany during the 1930s.

This contribution is focused on the “Casa Esagono” realized in 1957 by Vittorio Giorgini in Baratti (LI), Italy. The research objective is to lay the foundations for a restoration plan of this experimental wooden architecture, which is now in precarious conditions due to its location near the sea, and whose constructive features, has always raised great questions about the technical feasibility of a full restoration. The paper describes the workflow for the implementation of the H-BIM model, aimed to organise all the data deriving from the historical and on-site research, and the restoration programme. The historical analysis about the house and the architect was the basis for the geometric survey and the analysis of building materials. All building components were subjected to visual analysis aimed to identify deterioration forms. The proposed conservation approach aims to maintain as much of the original elements as possible, while increasing their durability. H-BIM revealed to be the ideal tool to manage the entire restoration process, whose ultimate goal is to celebrate Giorgini's work, to exploit the potential of the house as a cultural attraction.
