Efficient Earth-Sheltered Homes Department of Energy

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. Last month Dezeen featured Villa Aa, a concrete house in Norway made "invisible" by being nestled into a shallow hill. Here, we round up 10 other half-buried and underground homes partially hidden from view. Concrete and concrete alternatives are the most commonly used material for the construction of underground homes.

Underground Homes That are Crazy Cool

To me, earth shelters embody what simple living is about by encouraging an off-grid, eco-friendly, private life. Another thing you should do is plan your electricity earlier than you might for a traditional house. With an earth shelter, you can run certain elements through a conduit on the actual shell of your house.

Important Concepts Involved in Earth-Sheltered Home Construction

By harnessing geothermal heating and rainwater harvesting, Emily minimized her environmental impact and reduced utility costs. Her underground home became a showcase of eco-friendly initiatives, inspiring others in her community to consider alternative living options for a more sustainable future. Returning to prehistoric types of shelter is certainly not feasible in today's world. However, that doesn't mean that we can't attempt to re-create some of the advantages that came with our cave-dwelling ancestors.

Unique design opportunities

The town, widely known for its opal mines, is also unbearably hot, with temperatures routinely as high at 50 degrees Celsius (122 degrees Fahrenheit). Decades ago, local miners struggling with the heat experimented with building underground shelters. The natural coolness from the surrounding earth led to dozens of underground shelters, which continue to be inhabited today.

Earth-Sheltered Homes: The Lost Art of Building Underground

Many of these homes naturally only admit light from one cardinal direction (generally south). This makes any rooms that are not directly on the southern wall dark, and even the rooms on the south side will have strong and harsh shadows as everything is lit from only a single direction. To remedy this, you will need to either use skylights or cut through the berm on the other sides of the house so that you can place windows there. If you have ever come across a cave while hiking in the sweltering heat of summer or the frigid cold of winter, then you will be familiar with this second design concept. The idea here is that the temperature of the earth several feet underground changes very little during the year. Sure, the air temperature of the area can range from 0ºF to 90ºF, but the temperature of the ground 6 feet down may have only gone from 40ºF to 60ºF, if that.

The Subterranean technique involves building the house entirely below ground level. This method is often employed in areas with extreme weather conditions or when homeowners prioritize maximum privacy and minimal impact on the landscape. Subterranean houses are hidden beneath the earth’s surface, offering a unique and discreet living environment. Each construction technique presents its distinct advantages, contributing to the allure and innovation of underground living. Mountainous and hilly terrains pose unique challenges for construction. Underground houses can be integrated into slopes, taking advantage of the natural landscape to provide stability and blend harmoniously with the surroundings.

You can expect to have a life-changing experience in this home nestled in the beauty of nature. The house has been built to offer its residents the best retreat that one could envision. If you love a place where you can sit and enjoy the silence starring at the beautiful view outside then this place has a lot to offer you. The two neighboring hills are now part of the underground home, they protect it from the elements while it takes full advantage of them from a thermal point of view. A small residential ensemble, one that nestles a total of 9 houses which are connected with one another through sets of stairs, all wrapped around a small lake, lush vegetation, a loot of greenery.

However, underground homes are not actually the dark, humid, cave-like dwellings you may be picturing. These homes can be avant-garde, energy efficient, and designed in a classy, aesthetically appealing way, which is why they’re loved by people all over the world. Often times this type of housing is preferred in other countries when there is the presence of extreme weather conditions. While some underground houses or dwellings are entirely submerged below the earth’s surface, not all underground houses are.

Q. Who can benefit from building an underground home?

These earth shelters are built into surrounding hills but still have one outside facing wall. While this model has a smaller interior, it’s great for minimalists who want to try living with less. These earth shelters are unique in the way that they incorporate natural elements into the inside of the home as well as the outside. The house is fully submerged in the earth, with interior walls lined with beige and white stone. It offers low visibility and uses trees, bark, and plants throughout the inside of the house. Contractors will often build light tubes into the roofs of the structure to pull in sunlight and distribute it throughout the interior of the underground home.

By blending the structure with the natural topography and landscape features, homeowners can create visually stunning and seamlessly integrated dwellings. One of the primary benefits of building an underground home is its exceptional energy efficiency. By harnessing the earth’s natural insulation properties, underground dwellings require significantly less energy for heating and cooling compared to traditional above-ground structures.

Concrete is the most common choice for constructing earth-sheltered buildings, because it strong, durable, and fire resistant. Concrete masonry units (also called concrete blocks) reinforced with steel bars placed in the core of the masonry can also be used, and generally cost less than cast-in-place concrete. Natural drainage away from the building is the best way to avoid water pressure against underground walls, but installed drainage systems can be used to draw water away from the structure. It can also take more diligence to resell an earth-sheltered home, and buyers may have more hurdles to clear in the mortgage application process. The atrium design is hardly visible from ground level, creates a private outdoor space, and provides good protection from winter winds.

Proper waterproofing and drainage systems are incorporated to mitigate any potential water infiltration issues. In arid and desert regions like Phoenix, AZ, where scorching summers and limited water resources pose challenges, underground houses excel in their natural insulation properties. These homes remain cooler during hot days, providing relief from the intense heat. Additionally, underground houses can incorporate rainwater harvesting systems to mitigate water scarcity issues. The thick layer of earth surrounding underground houses provides excellent sound insulation, creating a peaceful and quiet living environment.

In the meantime they lived in a big dehumidified tent inside the cave, which once served as a roller skating rink. The couple faced considerable hurdles with getting fresh air and meeting egress requirements, it’s all quite the story. Make sure to avoid the five common building code violations and common National Electric Code violations. Well, these people took that dream one step further and built themselves a house in a hill. This is a really neat idea to have a self-sustainable home underground.

Over in Australia, abandoned mines were converted into homes, which can help people deal with the heat of the Australian desert. Much of the home was built with concrete, which presented problems of its own. It was a three bedroom, 2,000-square foot home that held a number of temperature sensors and gauges to measure humidity inside and out, as well as calculate energy consumption to the last watt. Some years later we now have these amazing devices that will turn your abode into a smart home. But what is so amazing about this gorgeous home is how well it is hidden into the hillside.

Careful planning and thoughtful design choices contribute to a comfortable and practical living environment in underground homes. Underground homes also drastically reduce the number of natural resources that go into the homes we build. For a 2,600 square foot traditional home, an average of 16,380 board feet of lumber goes toward framing alone.
