Ever since Tadao Ando started to establish himself more than thirty years ago as one of the best designers on the international scene for the rigour and character of his works, his intense activity has moved tirelessly between private residences and public buildings. Each of these works has added a small piece to the construction of a cohesive path based on a strong and clear use of geometry, the employment of few materials in the right proportions, the harmony of the spaces and a strong sense of the relationship with the landscape. From this point of view, the extensive series of museums designed and built by Tadao Ando in Japan, Europe and the USA forms an important body of work that tells of the Japanese master's design philosophy perfectly. This book has been put together with the architect, who, through an important and exclusive series of study sketches, images and models, tells us of his works and his way of seeing and conceiving architecture up to the definitive construction of the museum. From the early buildings accomplished in Naoshima, Osaka and Oyamazaki, through the Pulitzer Center in Chicago, the Museum of Modern Art in Fort Worth and the restructuring of Palazzo Grassi in Venice, readers will be accompanied into the reserved and rigorous world of Tadao Ando, gaining a sense of the “secret” of his project work.
