Building Materials and Construction Components Design Plastidobe Ecological Housing by Abel Gómez Morón Santos Plastidobe is a self-build, environmental, bio-structural, sustainable, inexpensive housing system. Each module used to build the house consists of 4 recycled plastic ribbed plaques gathered by pressure on the corners, making for easy transportation, packaging and assembly. Moisturized dirt fills each module creating a solid earth trapezoidal block that is acoustic and water resistant. A galvanized metal structure creates the ceiling, later covered with pasture serving as thermic insulator. In addition to that, alfalfa roots grow inside the walls for structural reinforcement.
