Small postal offices, built between the Seventies and Eighties of the twentieth century in Italian urban centres that were not provincial capitals and with a population of less than 1500 inhabitants, were the result of an impressive public building program and a complex research work coordinated by the architect Pierluigi Spadolini. The study was the basis of the first pilot experiment of the application of industrialized processes in a national public building program. The innovative contents of the project involved all phases of the building process: from the contract management process to the architectural study, from the relationship with the construction and production companies to the rationalization of the procedures for the purchase, supply and storage of the elements for future maintenance works. Some of these post offices have been demolished, but many are still in use and are very recognizable in the Italian suburbian context. This book aims to participate in the enhancement of this built heritage, considered as an icon of the transition from a building approach with essentially traditional features to the rare experiments of industrialization of construction processes, also extended to the small peripheral areas of the country, sporadically involved in the processes of modernization of Italian building techniques.
