Pioneers work with natural, local materials as arable farmers or in construction. Luc and Wout de Wit grow hemp in Utrecht, among other things, with which they will build biobased tiny houses. The Drenthe farmer Koos Vos has become a grower of elephant and mammoth grass. Landscape architect Julia Watson shows the Fab Tree Hab, a building partly built by willows, in the woods north of New York. A new perspective for farmers and builders, which also provides nature restoration and a healthier living environment. Is it too good to be true? Not if it is up to these pioneers.
