This is a set of two books with decent thickness, and I was very excited while unwrapping it. Nevertheless, as I started flipping through the pages of one and saw just images and images I thought maybe the other book would have more content (One is Design and the other Construction, so I figured the second would have more details or specifications) but I opened it just to be disappointed again.
This is the format: on one page a big render of the project, on the opposite page a few isometric drawings not too different from what is on the cover and with not much added. Some have a small vertical strip of tiny text on a side.
This book has no good explanations, details, or real information whatsoever. The text size (not too much of it, as I already mentioned) is terrible and seems to have been copied directly from the architects' websites like taking a screenshots and pasting them together in Photoshop so the letters are very small. I was very anxious to get this book because I also own "Yes is More" by BIG, and even though it is not perfect, the projects are explained in a funny and different way. And while "Architectural Diagrams" includes some of BIG's projects, you can get much more content if you just go to their website [...] Also, A LOT of the projects are by JDS Architects, you can just go to their website [...] and see what would be in the book, just in a better format because you can actually know what the project is about.
Don't be misled by other comments, if you like Ching's books, because it is not even close. What the most important thing in a diagram is, is actually the process; a red arrow pointing nowhere with a blue line coming from the opposite side, and then five black dots indicating something that you don't know what it is... not much to learn from it.
Do yourself a favor and just google "architectural renders" or "architectural concept diagrams," and save the money. Or I would recommend you decide to buy it only after having had it in your hands and took a good look at it.
