From the drawing boards of some of the world's most renowned architects -Tadao Ando, Zaha Hadid, Mario Botta, Michael Graves, to name a few- comes this artistically rendered collection of rough sketches. As a unique expression of the artist's own distinctive style, these are sketches that are unplanned works of art in themselves Set alongside full-colour photographs of the corresponding completed building or project, they provide a rare and invaluable glimpse into the inner workings of each master's studio.
