I was afraid of too austere book upon receipt, before opening. I do not know why. Long texts, pictures correct but not always top. In fact you really have to start and play the game c is to say, quite simply "read" ... You really learn a lot and above all the book reviews successively everything that makes architecture: forms, types of spaces , materials, currents ... C is very comprehensive !!! And this book soon became a sort of "bible", a comprehensive course on architecture .... The title is a bit misleading: all these "ideas" n not "revolutionized" architecture, they have the sitting, through the ages. Because it is interesting as c: the book is both thematic and historical. It runs through the various great movements of this discipline at the same time we review everything that makes architecture. In short, a very pleasant surprise after a first grip. Because the book is not "big beautiful book" but my level it is much better that some e who eyeful that we have not really want to read them. I am very happy to have this book on my coffee table ... And not just for "snob" set because every time I opened I read it and I enjoy intellectually. PS: translated from English but it feels not, which is not always the case.
