Multidimensional Measurement of the Level of Consistency of Farm Buildings with Rural Heritage: A Methodology Tested on an Italian Case Study

The industrialization after World War II marked a severe discontinuity between rural heritage and contemporary farm buildings. Rural landscapes have thus become more and more uniform; historical buildings are often abandoned and degraded, while contemporary buildings are often disconnected from their surrounding environment. Besides aiming to protect and restore rural heritage—more and more acknowledged as a common good contributing to societal identity—attention should be paid to increasing the quality of new buildings, a crucial issue to improve landscape quality in everyday landscape contexts. Based on a series of previous studies carried out to develop and test a robust methodology allowing the analysis of the main formal features of rural buildings, organized in a comprehensive framework known as the FarmBuiLD model (Farm Building Landscape Design), this study aims to perform an integrated and compared analysis of sets of traditional and contemporary rural buildings through experimental trials on an Italian case study. In particular, the study focuses on defining and measuring indexes allowing the quantification of the level of consistency of contemporary buildings with the traditional typologies. A contemporary farm building is evaluated based on the distance of each of its formal features from those which proved to be representative of the corresponding traditional building type, evaluated through a cluster analysis of the typological characters of traditional buildings in the study area. The results showed that different degrees of dissonance can be detected. Similarities have been found, in particular with respect to the shape of buildings and their closure with regards to landscape. The major dissonances are related to the perception of buildings as flattened on the ground, due to their excessively elongated shape, and in the case of buildings completely permeable to landscape, this being necessary for structural purposes and for the type of use of historic buildings. The expected impact of this study is to provide designers and planners with indicators allowing the evaluation, on an objective basis, of the level of consistency of new buildings with local rural heritage, thus supporting both design phases and project evaluation as well as building management processes (maintenance, restoration, extension, change in use, etc.).
