They employ the techniques of adobe, cob, earthbag / superadobe, straw-clay, clay wattle, wattle-and-daub, earth and lime plasters, earthen floors, and certain kinds of bamboo and strawbale construction. They use these techniques to work with both new construction and to retrofit existing structures. They also offer various workshops in art and building techniques.
