David and Carrie Chew live in a house made of straw. It has two bathrooms, a modern kitchen and a packed earthen floor. The exterior walls are made with stacked wheat straw bales covered in plaster.
Proponents of modern straw-bale construction highlight the sustainability of sourcing materials from local farms and natural insulation provided by straw. The thermal mass of the floor and wall plaster basically stabilizes your temperature through day and night and the thickness then reduces sound.
