The study presents a synthesis of the research conducted on building construction in Italy during the early years of the twenty-first century. The primary focus is on the analysis of the structural description. This analysis has been incorporated into a systematically organised collection of fundamental terms with defining attributes: character, decoration, compliance, and rehabilitation. The lexical structure can be traced back to the building environment from which it originates. Furthermore, this framework intrinsically engages with processes of reconstruction and the exposition of diverse construction techniques. Through this approach, it has been possible to recognise morphological and typological traits embedded in distribution characteristics. In this context, the knowledge of building restoration and recovery is assessed through architectural drawing and surveying methodologies. These elements directly contribute to research and analytical processes. The taxonomy of construction defines an overarching system that organises practical criteria for recovery and reconstruction, linking them to the various phases and experiential knowledge of building and structural techniques. In doing so, this system ascribes meaning and value to contemporary conservation practices. In particular, it recognises the historical importance of heritage that is vulnerable to speculation or destruction.
