This book explores the concept of Co-Dividuality, an architecture that expresses a new response to joint living in the age of post-individualism, social media, and sharing economy. The focus lies on current experimentation in Japanese architecture and presents thematic homes with shared spaces designed as a result of warm, simple, fun and contemporary design reflections. In addition to their private room, the co-tenants have large common areas where they can practice urban farming, create a start-up, cook together, or experience new spatial ergonomics. It is an overview not only on domestic space but also on projects where there is a multifarious mix between public and private spheres. What is Co-Dividuality? reflects on how we might want to live tomorrow. The book includes projects of Kengo Kuma, Kazuyo Sejima, Ryue Nishizawa, Shigeru Ban, Sou Fujimoto, Satoko Shinohara, Ayano Uchimura, Taichi Kuma, Junya Ishigami, Suppose Design, Naruse Inokuma and Masuda + Otsubo among others
