The redevelopment project of the Da Vinci and San Nicolò elementary school aims to restore the architectural and functional value of the building, which has undergone several changes over time—both in use and in the aesthetic of its envelope. Originally built in 1904 as a military barracks, the structure was later used as a quarantine facility and, after the First World War, converted into a school. Throughout these transformations, both interior and exterior alterations significantly compromised the recognizability of the building’s historical character. The intervention involved the partial demolition of additions from the 1990s, the restoration of the historic façades through repair and reinstatement of still-identifiable elements, and a modern, abstract reinterpretation of those architectural features that had been lost over time. An example of this approach can be seen in the string courses and window frames, reimagined in simple reinforced concrete forms to clearly distinguish the new intervention from the original structure. At the same time, the project was designed to improve thermal and acoustic comfort through the addition of insulation, shading elements, and a reorganization of the interior spaces in line with contemporary educational and psycho-pedagogical principles. A significant extension was also planned and constructed in the rear courtyard, spread over three levels, to house shared facilities such as the cafeteria and an auditorium. The new volumes engage in a dialogue with the existing building through their geometry, alignment, and color scheme, while deliberately standing out through their materiality. A play of light and shadow created by protrusions and recesses enhances the perception of the whole. The project’s aim was to return the building to its historical dignity while making it functional and welcoming for the needs of today’s students—emphasizing natural light, accessibility, and a continuity between past and present.
