Understanding the Building Regulations by Simon Polley -- I was not assisted by this book, i expected from the title to gain an insight into the building regs, it was not to be. Where you may expect an expansion and worked examples of the more complex issues this book refered the reader back to the originals. Where you might expect explanation of the underlying ethos, there was a poorly drawn cartoon. Where you might expect a comparison of methodologies with reasoned argument and recommendation of particular methods in particular situations and appropriate case histories, nothing.
Some people may find it useful, maybe the receptionist at building control, i found it quite slight.
