This book is subtitled How to carry out environmentally friendly improvements to your home which, whilst descriptive of the contents, also undersells a very good book which should be required reading for anyone wanting to lessen their carbon-footprint, or just cut their utility bills. Apart from the sheer quantity and quality of the suggestions, what I particularly like about this book is that the suggested improvements don't loose sight of the fact that they should look good, as this is a home being talked about. You will save the cost of this in no time - really! 168 A4 format pages. Vast numbers of illustrations, nearly all in colour. Hardbound. Haynes Publishing
