"A must-have book for anyone interested in natural and sustainable building. It expands the possibilities with practical and essential information on this user-friendly method of construction."— Will Beemer, Director of the Heartwood School for the Homebuilding Crafts and author of Learn to Timber Frame."Kelly Hart and Dr. Owen Geiger ( who wrote the very informative Foreword ) probably know as much about earthbag building as anyone. Friend Kelly has always had a clear and concise way of explaining his subject, both in lectures and in his several books. I've never built an earthbag structure, although we once did a cordwood building on an earthbag foundation in New Zealand. But I wouldn't even attempt it without studying this book thoroughly and referring to it throughout the building process."— Rob Roy, Director, Earthwood Building School and author of Essential Cordwood Building"There is an urgent need for more sustainable homes and earthbag construction offers excellent, affordable, strong eco-friendly housing using natural and local materials. They are beautiful, comfortable and robust. This book is a comprehensive, practical and inspirational guide that is both detailed and easy to follow. Hart demonstrates that anyone can build a home, so use this book and give it a go."— Penny Pickerill, Professor of Environmental Geography, University of Sheffield, UK and author of Eco-Homes: People, Place and Politics (Zed Books)"Who doesn't love earthbags? Only people who don't know about this most versatile of earthen building techniques, suitable for building inexpensive low-impact homes on most parts of the globe. With just a pile of dirt, some bags, barbed wire, a tamper and a few basic tools, you can build an earthbag dome, retaining wall, or root cellar. For over 20 years author Kelly Hart has been experimenting and promoting simple DIY ecological building techniques, especially via his excellent web sites. Distilling both his own hard-won experience and the combined wisdom of the rapidly-expanding worldwide earthbag network, Hart delivers a thorough, detailed and readable guidebook that tells you everything you need to know for success with this potent technique."— Michael G. Smith, co-editor, The Art of Natural Building and co-author, The Hand-Sculpted House
