Abstract

This work originated from a simple question: is it possible to reconstruct a destroyed architectural decorative element starting from documents that describe its details, shape and constitutive materials? An important limitation in the past was the lack of technologies and materials that could replicate an object like this in detail. Only a few years ago technology was not yet able to ensure accurate reconstruction characterized by an adequate formal aesthetic level both in terms of materials and finishes. Nowadays, this gap has been filled thanks to the development of Computer Numerical Control machines (CNC) in production processes. In this contribution, we present part of the restoration of Villino Florio in Palermo, built by the architect Ernesto Basile on behalf of the Florio family between 1899 and 1902 and partially destroyed by a fire in 1962: it is one of Italy’s first architectural works in the Art Nouveau style, and is considered a masterwork within the European panorama. The restoration, directed by the Soprintendenza BB.CC.AA. Di Palermo, also involved the monumental staircase, with a complex wooden floral pattern (‘ramage’) used to decorate the ceiling. Starting from the relief of the environment and from the old photographic documents, a 3D model of the ramage was retrieved. This formed the basis of information necessary for the subsequent reproduction of the subject with CNC machines on oak modules, assembled and finished just as they appeared in the photographs before the fire. A numerical approach made it possible to control the entire process by adopting structural solutions to avoid overloading the ceiling with excessive weight.
