The project of Palazzo Nardini, assigned to Paolo Marconi in 1984, involved the reuse of the complex extending towards the Archivio Storico Capitolino. The brief sketch board signed by Marconi himself, collected in P. Marconi, "Dal Piccolo al grande restauro", Venezia, 1988, ill. IX-XX, here republished, describes with great effectiveness the core principles of the project: analysis of documents; metric, constructive and critic survey; selection of the areas to be demolished or fortified; organic typological asset and organization between elements to be recuperated.
