This book highlights the possibilities arising in architectural design through the integration of Generative AI technologies in the design process. Generative Artificial Intelligence (GAI) tools, methods and techniques are gaining popularity in architectural design, producing illustrations of fictional buildings, providing floor plan solutions, simulating human behavior or providing 3D massing solutions for buildings among others. Some architects find them useful and inspiring, while others criticize them as superficial or feel threatened by them. Consequently, the question of how to integrate AI into the architectural design process becomes crucial. This book casts light on how such an integration may be possible in architectural research, practice and pedagogy.  It explores the latest methods and techniques through fourteen articles by renowned researchers, practitioners and educators focusing on the design process and the arising possibilities and challenges in 2D and 3D generation of spatial solutions. Our findings provide an overview of original, cutting-edge AI technology articles in the realm of architectural design as well as insights into how AI might change architectural design processes in the future.
