Transformation is conservation. Modification as project’s tool

The paper identifies purposes and modes in order to define the construction method of the modification language, where the modification is intended as a conceptual instrument leading the architecture s planning (Gregotti, 1984) and, moreover, it talks about the overlap of physical - operational level, and of the linguistic - conceptual level, that the term includes. The permanence of the issue, that determines the constant actuality, mainly refers to a particular context, as the Italian one, in which the presence of environmental pre-existences (Rogers, 1955) includes the need for an inclusi- ve act of maintaining and conservation that is opposite to the exclusive principle of tabula rasa be- longed to the Modern Movement. Therefore, the project is considered as an element of investigation and coherence with the characters of the place that they involve, especially, both the presence of history, a permanent entity between collective culture and architect’s individual culture, and that of discipline, general rules and traditions system that translated and projected toward new interpre- tations by the modification project.
