The first 40 pages are filled with Ken Yeang's idea of how his approach is different from the rest.
The eco frontier architect put his hands on the bigger scale of the space, urban design to masterplans of the small regions to a town concept.
I like the clarity of the writing-introduction, but, I find his Green/Grey/Blue/Red concept layers are still sketchy and they are not meticulously or accurately explored in the rest of the pages/projects further.
Still over the decade, I find his works still refreshing and he often challenges the conventional design process.
The presentation and narrations of the projects selected are not entirely consistent and often hurried to show very inaccurate flashy images here and there, that only confuses the reader.
I don't think he is a visionary master architect of today IMHO. His designs are always linear repetitions of his past works. But, if you need a reference for your eco master plan works in brainstorming stages, this book might be a good bstart, and it comes with some decent diagrams to look at. Again, not accurate or perfected enough.
