Both this, and other architectural books from Countryside Books are excellent. I am an interior design student and found this book indispensable when studying the Georgian era (I also used 'British Architectural Styles' by Trevor Yorke - which I would also recommend highly). The illustrations are very good, and the text to the point and readable - although this is a 'simple' book, it is by no means 'simplistic', and is a perfect introduction to the subject. Small enough to put in your bag (or a large pocket!)- it is invaluable for taking out and about with you if you are interested in historical architecture.
