This volume explores the subject of facades, from both an architectural and an urban point of view. An analysis of the historical background and the progressive reduction of its thickness is followed by some itineraries of contemporary works whose genesis is explained in interviews with the protagonists. Between the Building and the Street, the result of many years of study and research, it is a work that deals in a complete way with the theme of the facade through interpretative paths, evolutionary readings, compositional itineraries. One of its strengths is the study of the etymology of the word “facade” through the centuries, in dictionaries, encyclopedias, and in all the means that have helped to spread knowledge, from the Accademia della Crusca to the present time.
