The building process begins with a civil engineer, who evaluates soil conditions and water runoff. Dave South, the publisher of the Dome News for the Monolithic Dome Institute, recommends that a structural engineer design a building strong enough to support the load placed over the home. When you build into the ground, the earth functions as a thermal mass, helping to maintain a comfortable interior temperature year-round. However, you must carefully plan the structure itself to carry the load of the earth. Written for the layman, this is the fully revised and updated guide for individuals and businesses interested in generating their own electricity using the sun. You’ll be inspired to dive deeper into green living and feel empowered by your choice to help the environment and create a healthier household.
These buildings use less water, energy and other natural resources. Building with compressed-earth blocks makes sense, and not just because most of the construction materials are right under our feet. Earthen walls regulate temperatures, dampen sound, repel mold and, with the right build, they can resist earthquakes, fires and other disasters. Clay-slip straw is straw covered in a clay slurry that’s made by soaking clay in water until it becomes suspended.
Step 5: Floors and Interior Finishes
For example, retaining walls must be constructed to hold back the weight of the earth. Especially as it becomes water-logged, the earth's hydrostatic pressure can exert great stress on the walls. Drainage pipes help protect the structure from water infiltration.
Rammed earth or “beaten earth” is a fairly simplistic building technique but it can produce some of the grandest earthen buildings. It has been used on five continents and continues to be used in Australia, China, France, Germany, Morocco, South America, and it is having a small revival in the United States. Consider the earth constructions at Jericho in the Jordan Valley which date back to the tenth millennium B.C. Or the sections of the Great Wall of China which were built with rammed earth. There is an incredible amount of history and knowledge for us to rediscover which can be applied to the future of building.
Better Natural Finishes for Earthen Materials
Learn about everything from site preparation, design, and foundations all the way through to the roofing and finishing work. Every major component of building a cob house is covered in this instructional eBook. This 93-page eBook will instruct you, in detail, how to construct buildings with cob and earthen materials. The superadobe system was developed by Nader Khalili in 1984, but similar methods have been used before that time. It was common for buildings to be constructed out of sand bags on the fields of war, starting before World War One.
Of course, we covered above the potential cost savings due to the simple architecture that is involved. Another bonus in terms of cost savings is that of insulation. The surrounding earth and earth roof will act to prevent heat loss, providing a natural form of insulation to your home. Of course, depending on your climate, you might still require regular insulation, but the earth might do a lot of the job for you.
The first is known as an underground home or “underground structure,” which is built below-grade or completely underground.
It was a springboard that propelled the concept and made it recognized, worldwide. Scroll down to read about five different earthy approaches to building eco-friendly homes for today. Concrete is the most common choice for constructing earth-sheltered buildings, because it strong, durable, and fire resistant. Concrete masonry units reinforced with steel bars placed in the core of the masonry can also be used, and generally cost less than cast-in-place concrete.

Adobe, also known as mud brick, is a building block composed of mud that is dried inside of wooden forms by the heat of the sun. The mud used comes from subsoil that contains clay and sand. The amounts will vary in every geographical location so its best to test your soil. Chopped straw is also included sometimes to help prevent cracking. Earth building techniques have been around for thousands of years.

Dr. Jackie Craven has over 20 years of experience writing about architecture and the arts. She is the author of two books on home decor and sustainable design. While the whole idea sounds fantastic and you don’t have to be an engineer, architect, or construction worker to build it, it’s still a daunting mission.
Today, the superadobe system has developed into a sophisticated and modern building system fit for all types of needs. Interest in the system has continued to grow over the past few decades. There are a number of old and new examples of adobe buildings throughout the world. There is even a 100-room, four-story resort hotel constructed out of rammed earth in Queensland, Australia. Rammed earth dates back to the time of the pharaohs of Egypt and had its roots in North Africa and the Middle East.
Here you can see the walls of the covered porch and the two doorways into the home. Here you can see a gray line of cement between two rows of blocks. A concrete layer locks in the rebar beam, which is now covered and not visible, and the vertical rebar pictured.
A mix of water, clay subsoil, sand and straw is placed in forms, and the resulting blocks are stacked under a cover to air dry. Door and window frames are usually structural boxes (known as “bucks”). Because adobe can be mass produced and is modular and storable, it lends itself to the slower, phased approach typical of do-it-yourself construction. Because you’re making the blocks, you can adjust their dimensions to meet your needs.
When working to build an earthen dome home, there are many different types of building materials to choose from when building the walls. Though not suitable for colder climates, the walls of this 500 square foot home are built with cement blocks and clay bricks because compressed earth blocks were not readily available. Earthbag building surpasses most building methods in terms of structural integrity, low cost and use of sustainable in resources.
Your first construction step, then, should be the sieving of the soil through a slanted screen of 1″ mesh hardware cloth to separate out any big stones, roots, etc. Spread a tarpaulin over the screened dirt to protect it from precipitation (if the soil contains more than 10% moisture it will puddle, not compress). When you make a ball of earth in your hand it should hold its shape but break and scatter when dropped. The plaster-coated earth blocks were colored with a lime-based finish. Tinted with mineral oxide pigments, the finish produces no toxic fumes and the colors do not fade.
Earthbound: 5 “All Natural” House Styles
Dome-shaped earth bag house keeps residents cool in ColombiaLa Casa Vergara’s uncommon dome shapes may captivate the eye, but what’s underneath is most impressive. The Bogota home, built by architect Jose Andres Vallejo, is made from “earth bags,” or tubular bags stuffed with - you guessed it - earth. These bags are stacked atop each other and encased in concrete on both sides, which work together to prevent both earthquake and water damage. Exposed timber beams and plentiful daylighting make everyday living a bit greener and the $28 per square foot price tag puts the home within many buyers’ price range. An earth-bermed shelter is built into or against—you guessed it! In essence, the topography of a building site, whether naturally formed or shaped by men and machines, allows for habitable space to be carved out in the creation of a semi-subterranean dwelling.
You’ve seen them in such popular movies as Lord of the Rings and The Hobbit as well as extreme home shows—quaint and cozy houses built either completely underground or nestled into a hillside. On flatter sites, you can pack the earth against the exterior walls of your home so that it slopes away for drainage. But the advantage is that the earth adds yet another insulating plane to the home. Underground homes are typically made of reinforced concrete because it does not degrade and has high compressive strength.
