This book explains this new direction in architecture, so that in a few decades what may now seem extraordinary will be commonplace. It is a method to build or renovate close to what may eventually be known as bioconstruction — a building system with recycled or recyclable low-environmental impact materials, or materials that can be extracted by simple processes at a low cost. Let’s take a room-by-room look at the house, from the living room to the bathroom including the garden trying to preserve materials so that they have a longer life. We will give priority to environmental and technological measures in the design phase of a home to save water and energy.
