What needs to be considered in this context? The manual *Building with Earth* , which has been translated into many languages, describes the building technology of this material. The physical properties and characteristic values are explained in a hands-on manner: with proper moisture protection, earth buildings are very durable, and in particular the combination with wood or straw allows a wide spectrum of design options. Numerous built examples demonstrate the range of applications for this fully recyclable material. * Fifth and revised edition of the reference work on rammed earth construction * With seven new and relevant international case studies * Many drawings illustrate various construction methods
