The first book to document the Tokyo-based architectural firm, one of the most innovative practices working today. Achieving near cult status among architectural students around the world, Yoshiharu Tsukamoto and Momoyo Kaijima of Atelier Bow-Wow have built a career confronting the challenges posed by dense urban environments. Their city houses—enclosed in vibrant, idiosyncratic forms—are distinguished by their capacity to accommodate the changing needs of the occupants. A basic feature is the permeability of interior spaces, where public and the more intimate places co-mingle, often in vertical structures with a total floor area that rarely exceeds 200 square meters. Atelier Bow-Wow has a dedicated research division that has published a number of treatises on vernacular architecture. This book will feature their newest research, including plans, as well as explorations on mobile or portable projects. The book includes key projects such as the Mini House, The Sway House, the Juicy House, House and Atelier Bow-Wow, the House Tower, and the Aco House.
