Architecture in modern Western societies is characterized by intense and continuous renewal. How and in which sectors do innovation trends appear? What are the relations of the new with the structures of society? By what process does the new acquire value and become established? Who invents the new, how and with what mechanisms? The course will be oriented to the investigation of the conditions that led architecture to a competitive adherence to the processes that guarantee changes in form and content. It will also study the new and innovative elements of architecture during the 19th and 20th centuries, the ways in which they were produced, their characteristics and coordinates, as well as the separatist tendencies and rivalries that appeared before the innovations prevailed. As a task, students will be asked to engage, through a critical commentary of various innovations, with exploratory efforts to produce innovations in any field of architectural thought.
