Timber-framed structures exhibit a serial character, which over time has led to proper standardization and organization at an industrial level, encompassing both the production process and assembly. Historically, such buildings were not typical in Liguria. However, after the Universal Expositions of the late 19th and early 20th centuries, their popularity surged significantly alongside the growth of tourism. Indeed, between the end of the 19th century and the first half of the 20th century, numerous villas and country houses were constructed using timber-frame technology. As this technique became increasingly standardized, it was applied not only to the supporting structure but also to the infill. At this stage, Eternit panels were introduced, and various construction types were detailed in manuals produced by the Eternit company. These manuals also provided information on the most appropriate panels for each application. Research on these artifacts forms part of a broader university research program aimed at enhancing our understanding and techniques for the conservation of contemporary architecture.
