This book is excellent for the professional designer or aspiring one. As a homeowner looking for direction on my own backyard, this book was a little too advanced. It is illustrated with whimsical cartoons & stickfigures. I found these to be completely unhelpful, only amusing. Also, it is written by an English author, so some of the terms and verbage were unfamiliar to me. Likewise, example scenarios given are more suitable for English climate and landscape.
