This book, on line since 2012 like part of Systemic Habitats Website (systemichabitats.it), edited by me, Michele Leonardi Architect, is mainly dedicated to architecture and urbanism. It is not a book conceived only for specialists, but for anyone interested in architecture. For example, two masters of modern architecture like Frank Lloyd Wright and Le Corbusier, were not graduates. Otherwise looking at the distant past, the Roman emperor Hadrian, the director of a masterpiece of all time such as Villa Adriana near Tivoli, not even he was qualify himself as "graduate in architecture", but simply like experienced architect. And not counting the architectures without architects that dot the world: from the trulli of Alberobello in Italy to the tulou in China, from the French cathedral builders in early second millennium up to the oasis of Sahara in the last millennia. Until to get to one of the oldest rights of the world: that of building your home yourself. But this does not mean that anyone can improvise as an architect, especially in our day, in the age of specialism, cloning and absolute conformism. The meta-message included in this book is essentially aimed to the "not born old" new and old generations: don’t let yourself be overcome by pessimism and by Cassandras. Don’t believe in clichés and the ignorance spread by the mass media, nor in certain forms of scientific dogmatism. Because humanity today has all the knowledge available and all the modern and traditional technology to solve any real problem, including the energy transition, indeed, not a problem, but a new opportunity and a new frontier.WHAT IS A SYSTEMIC HABITAT? The principles of Systemic Architectures and Constructions are exposed in my essay entitled "Toward a different habitat : 36 projects and realizations of Luigi Pellegrin Architect". However, in a nutshell, the basic assumption is that nature is systemic. It’s still valid that nature is the best teacher, "natura naturans", without for this reason divinizing it. All this beyond the form that an architecture or a building can take, because, as is well known, the forms are unlimited. Man and society are not outside nature, but inside nature (Serge Moscovici, 1972), being themselves nature. Let us not forget.
