Before deciding to design and build an earth-sheltered house, you’ll need to consider your building site's climate, topography, soil, and groundwater level. There are two basic types of earth-sheltered house designs—underground and bermed. This Summer, for a hot-minute we contemplated selling the Frost House and buying another house around the corner. An incredible Architect Designed home on our favorite street in Michigan City – Kenwood. The house that was up for sale was the first berm house in Michigan City. It was originally built in the 1960s for Dr. William Hall (a Dentist), who later had his Architect son add a small addition to accommodate his in-home dental office.

Because of the unorthodox design and construction of earth-sheltered homes, local building codes and ordinances may need to be researched and/or navigated. Many construction companies have limited or no experience with earth-sheltered construction, potentially compromising the physical construction of even the best designs. The specific architecture of earth houses usually leads to non-righted, round-shaped walls, which can cause problems concerning the interior decoration, especially regarding furniture and large paintings. Therefore, there is a drastic reduction in energy consumption required for the home compared to homes of typical construction. One of the oldest examples of berming, dating back some 5,000 years, can be found at Skara Brae in the Orkney Islands off northern Scotland.

This can reduce the likelihood of there being cracks or leaks at the joints where the concrete has cured at different times. The foundation of the buildings designed by Vetsch are built conventionally. On land that is relatively flat, a fully recessed house with an open courtyard is the most appropriate design. The most practical orientation in the Tropics nearest the equator is north-facing toward the aphelion (or perhaps northeast) to moderate the temperature extremes. Atrium designs have an increased risk of flooding, so the surrounding land should slope away from the structure on all sides. A drain pipe at the perimeter of the roof edge can help collect and remove additional water.
Important Concepts Involved in Earth-Sheltered Home Construction
Our team is experienced and efficient when it comes to earth-sheltered home building services. We design and build beautiful, durable, safe, and eco-friendly earth-sheltered concrete homes. This is one issue that will cause big problems in areas where building inspectors prowl. Code requires certain rooms in the house to have windows or doors of certain sizes in order for the occupants to be able to escape in an emergency where the main exits are blocked. This will cause big problems if you place bedrooms on a bermed wall (which they often are).

The Benefits of Switching to Solar Home Energy…
According to this theory, a bermed earth shelter would absorb the sun’s heat in the summer and gently release it throughout the winter, negating the need for additional heating. According to studies, bermed Earth-sheltered homes are more economical in regions with extreme temperatures and low humidity, such as the Rocky Mountains and the northern Great Plains. Earth can absorb extra heat from the house in hot weather or act as insulation to keep the house warm in cold winter because earth temperatures in these regions change far less than air temperatures. Overall it is more technically challenging to design an earth shelter compared to a regular home.
For a society moving away from the McMansions, the unobtrusive berm home provides an appealing selection. Around for thousands of years, earth-sheltered homes, specifically berm homes, began rising in popularity in the 1970s as mankind became more aware and concerned about our planet. With this new energy conscientiousness and desire to live sustainably, we began to look to our past for solutions, leading us to the modern berm home. There are various cement-like coatings that can be used as waterproofing. It dries and acts like a huge ceramic layer between the wall and earth.

Thanks to the earth surrounding them, earth sheltered homes maintain a year-round temperature of degrees, depending on your location. Therefore, earth sheltered homes are ideal for hot climates, cold climates and everything in between. Earth sheltering often requires heavier construction materials to resist the weight of the earth against the walls and/or roof. Reinforced concrete in particular needs to be used in much larger quantities per building.
Sculpting Spaces: The Role of Materials in Shaping Environments
Once the site is prepared and the utility lines installed, a foundation of reinforced concrete is poured. Usually, they are either poured in place or formed either on or off-site and then moved into place. If the walls, floor, and roof are all to be poured in place, it is possible to make them with a single pour.
Earth-Sheltered Home: An Eco-Friendly, Passive Housing Alternative
Disaster Resistance Another money saver here, because the earth is essentially protecting the berm home, severe weather events such as tornadoes will likely cause little to no damage as they pass. Also, if there is an earthquake, the berm home will move with the earth and therefore you can expect less damage. Lastly, earth is essentially fireproof, so homeowners can live knowing that a fire will not devastate their home as easily as a normal house. With all of these damage resistances, it’s no wonder that the insurance costs for a berm home are much lower, which, coupled with the peace of mind, makes berm home living an attractive option. A Berm-style home is built on flat land or a very small hill and earth-covered to form your own mountain. It could have covering from side to side and the top only, leaving the home more open in the front and rear, a “see-through home”.
Soil as the main building material and blending in with the landscape, earth-sheltered houses drastically reduce the demand for lumber. This massive new home is slated for construction in the hills of Bel Air, California. Clocking in at 26,800 sq ft we'd be inclined to call it a McMansion, but the home will in fact be built underground, rendering it virtually invisible. Chris Painter, a technology entrepreneur, had been on the lookout for a perfect spot for his new home and found it on a bluff atop Moraga Canyon in Los Angeles.
This works very well where the shape of the structure is unconventional, rounded or difficult to get to. Foam insulation requires an additional protective top coat such as foil or fleece filter to help it resist water penetration. The most frequently used waterproofing system includes a layer of liquid asphalt onto which a heavy grade waterproof membrane is affixed, followed by a final liquid water sealant which may be sprayed on. It is very important to make sure that all of the seams are carefully sealed.
Wood can be used in earth-sheltered construction for both interior and light structural work. Steel can used for beams, bar joists, columns, and concrete reinforcement, but must be protected against corrosion if it is exposed to the elements or to groundwater. It is also expensive, so it must be used efficiently to be economical as a structural material. Granular soils such as sand and gravel are best for earth sheltering. These soils compact well for bearing the weight of the construction materials and are very permeable, allowing water to drain quickly. The poorest soils are cohesive, like clay, which may expand when wet and has poor permeability.
At the centre of the shelter, an atrium or courtyard can be built to offer enough light and ventilation. Eco-Flex is an environmentally friendly waterproofing membrane that seems to work very well on foundations, but not much is known about its effectiveness in earth sheltering. The main challenge with these products are they must be carefully applied, making sure that every area is covered to the right thickness, and that every crack or gap is tightly sealed. Water can cause potential damage to earth shelters if it ponds around the shelter. Underground, these temperature changes are blunted and delayed, termed thermal lag.
Questions therefore arise as to whether certain structures are truly environmentally friendly. For example, raw materials must be extracted from the earth, transported and then manufactured into building materials and transported again to be sold and finally transported to the build site. Earth-sheltered homes offer a myriad of advantages that make them appealing to eco-conscious homeowners and beyond. Their storm-proof, earthquake-resistant, and fire-resistant qualities provide a sense of security and protection. Additionally, their exceptional energy efficiency, soundproofing, and low maintenance requirements make them an attractive option for anyone seeking a comfortable and sustainable living space. With their unique designs, bermed homes demonstrate the possibilities of combining practicality and aesthetic appeal, proving that embracing earth-sheltered living can be a smart choice for a greener future.
This alleviates the problem of warm air escaping the house through gaps around windows and door. Furthermore, the earth walls protect against cold winter winds which might otherwise penetrate these gaps. However, this can also become a potential indoor air quality problem. Another design type for a bermed home is called a penetrational bermed design. With this one, earth covers the entire house, except where there are windows and doors. The house is constructed at ground level, and the earth is built up (bermed) around and on top of it.
