This book reveals the origin, definition, and evolution of New Brutalism in architecture. The New Brutalism movement in architecture addressed a new way of understanding the urban dimension in the post-war period, and in particular the role of the architect in an insecure society. But the original definition was manipulated, diluted, and fragmented as the concept spread from Europe to the United States, Japan, and South America. New Brutalism follows its contributions on a global scale, as it challenged the ambivalent collaboration between critics and architects and opened a controversial debate over a new “international style.” Disruptive, revolutionary, and at times even Dadaist, New Brutalism steered the cultural trajectory of the Modern Movement. A corrective to the many myths and misinterpretations of the style, this book reasserts the foundations of New Brutalism and offers a close examination of its international influence and variations.
