Tony Johnson runs Earth House Holdings in Sooke, B.C., Canada. He specializes in rammed earth like his own house featured here. He used steel rebar and wool insulation, which results in exceptional strength when it comes to earthquakes and a much more insulated envelope for the colder Canadian climate. It is extremely energy efficient due … Read more
Penny Livingston-Stark is a designer and professor of permaculture who has worked for 25 years in the field of regenerative design based on non-toxic natural materials. She insists on the compatibility between bamboo and earth. Their similarities and differences help them to integrate remarkably well. “Earth and bamboo are not compatible with plastic vapor barriers … Read more
Researchers from Newcastle University have crafted a new bio-based material called “mycocrete”. Using mycelium combined with additional natural materials, the team can grow a tightly wound substrate stronger than previous mycelium materials. The knitted design can create 3D shapes without seams or waste. “Our ambition is to transform the look, feel, and well-being of architectural … Read more
From the earliest times the only way for humans to build shelter was to use locally available raw materials. Rammed earth is estimated to have been used since around 5,000 B.C., often enclosing a wooden framework with a mixture of raw earth combined with plant fiber. Thin wooden sticks can be driven into the ground … Read more
Natives from the Lower Sioux Indian Reservation in southwestern Minnesota are building a 20,000-square-foot manufacturing campus that will allow them to pioneer a green experiment, the first of its kind in the United States. They are growing hemp to process it into hempcrete, and then build healthy homes with it. Once the tribe makes this low-carbon … Read more
As a process that involves the layer-by-layer compression of gravel, sand, silt, and clay, rammed earth appears as horizontal stratification of earth tones. This can be controlled and explored through patterns, texture, pigmentation, and natural clay colors. The type of soil not only affects the mechanical properties of the rammed layers (the denser the material, … Read more
