I've had my hands on this book for only a few days but it's already at the top of my list of favorite books on LEGO (and I own or have read many of the books on LEGO design and building).I love this particular book because it is filled with page after page over wonderful ideas for any aspect of architecture. The book invites you to experiment with your LEGO collection to build ornate windows, sloping roofs, rounded walls, etc. This book is not a how-to guide. Different architectural elements are presented over several pages with different examples using different pieces. The text is kept at a minimum, giving short explanations when necessary and piece descriptions and part number (Great for online shopping for specific pieces).There are few instructions on how to build and when there are it is more if a diagram rather than a step-by-step guide. There are few examples of completed products. Most of the focus of the book is on different architecture elements in isolation. Its up to the reader to take these different ideas and construct an architectural masterpiece.Highly recommended for advanced LEGO builders. The book might be a disappointed for parents of younger children as the idea require a lot of very specific brick types (and often in vast quantities). Overall, inspirational and well-done. Highly recommended!
