I bought this to research and find references for concept art creation. I originally wanted a Book by Lebbeus Woods called the New City, but since it is out of print and it is a collectible and it is very expensive I started looking for alternatives. I found this book while browsing a magazine and found it is also out of print. I grabbed a copy before it was sold out and so far I must say that I'm impressed with the content. If you're an architect, concept designer or just love futuristic architecture for the sake of it, this is a must have.
