It is an indulgent delight to be asked to review a book, more so one of this stature that follows on from two previous noteworthy volumes. My shelves are full of architectural tomes which have only been skim-read, or worse, only flicked through – I know they are there and one day, yes one day, I will find time to read them. So, being given the responsibility to read each page of such a book feels like a privilege – and it must be said that this book is rather special.
