A Replicable Valorisation Model for the Adaptive Reuse of Rationalist Architecture

Adaptive reuse has progressively become a useful approach for generating new values concerning abandoned or underused buildings, sites, and areas to the extent that the topic is no longer conceived and perceived merely as a “bricks-and-mortar” issue. Instead, it has a dual nature: (i) one that is technical, linked to the difficult balance between low costs and fostering sustainable building solutions, and (ii) one that is social, which refers to social equity, well-being, and quality of life. Within this context, urban and architectural transformations are among those human activities that play a key role in shaping the territory in an increasingly invasive acceleration of urbanization processes. However, it is precisely here that adaptive reuse can counteract such alterations. This paper proposes a sustainable, economically feasible, and replicable valorisation model for the evaluation of adaptive reuse possibilities of a particular historical–architectural heritage, which is vast and widespread in Italy and an important example of Rationalist architecture. Such a model incorporates flexible and easily replicable spatial implications precisely because it is specifically related to the characteristics of an open-plan structure. In doing so, it aims to redefine the valorisation model based on a constant dialogue between the project and market analysis; the replicability of project strategies for “families” of historic buildings; and the need for the project’s ability to change and adapt according to emerging requirements.
