For even more inspiration and information, check out Barbara’s book. Our self builders, and the architects we advise, all say this book is invaluable as a resource to understand how to build with straw. It covers the whole building process, from foundations to internal plastering. Barbara has been designing and building with straw for 25 years – this book is a distillation of all her knowledge and experience. Originally published in 2002 it has never been out of print – revised in 2009 and 2015, the last revision taking in details of how to compress straw walls and how to build the roof first when doing load-bearing buildings.
