A comprehensive coverage of house designs. I found myself more impressed and interested by the traditional vernacular houses and cottages than the modern designs. There were one or two minor factual errors in the descriptions.
The biggest issue for me was the print size, which I think may depend on the edition of the book, but the paperback edition I read had miniscule print, each character less than 2mm so probably 6pt or smaller. I'm not at the stage of life to need reading specs, but I did need to strain my eyes to try read text this small!
Personally, I think I would have liked half the number of buildings and for each building to take up 2 pages instead of one. Some buildings were hard to understand from the description and the picture chosen, and there were some that I know I really like but if I had first come across them in here, I wouldn't have given them a second thought due to the lack of information and the way it was presented.
