I'm not a fan of Krier's views regarding the validity of most anything produced in a style that didn't originate 1,000 years ago. With that said, there are many sketches and analyses in this work that are helpful when one is designing an urban space. Krier's own work is present and used as examples, but the focus is on the analysis of different types of urban space. This is definitely a worthwhile read for anyone connected to the design of the built environment.
Urban Spaces is halfway to a picture book, and half of those pictures are extremely visually pleasing and interesting, and the other half are a break from the, admittedly occasionally dry writing. Rob Krier won’t really rouse you as much as his brother, and he won’t blow your mind quite like Montgomery, but he’s still got some really good takes on how to successfully design urban space which I think are certainly worth the time.
