“Another type of building is emerging: one that actually heals the scars of its own construction. It conserves rainwater and fuel and it provides a habitat for creatures other than the human one. Maybe it will catch on, maybe it won’t. We’ll see.” – Malcolm Wells, 2002.
An earth sheltered home uses the ground as an insulating blanket that effectively protects it from temperature extremes, wind, rain, and extreme weather events. An earth-sheltered home is energy-efficient, quiet, freeze-proof, and low maintenance.
Aesthetically, an earth-sheltered home blends in with the natural environment, leaving more yard space and more space for wildlife.
Fifteen feet below ground, the soil maintains a fairly constant temperature equal to the annual average temperature of the area’s surface air.
For example, if the average temperature in your area is 55, that means the soil temperature at 15 feet is 55 degrees and in the winter you will only have to bring the temperature inside your earth sheltered home up to thirteen degrees, to bring it up to a comfortable 68 degrees. That’s instead of bringing up the inside temperature 68 degrees if your home is above ground and the outside wind chill is 0.
In the summer, that 55-degree soil will also keep your home much cooler than an above ground home. Many earth homes incorporate passive solar designs, lessening even further the need for fuel for heating or cooling.
Here is a tour of an 1,900 square foot earth-sheltered home built by architect Alan Shope. Shope explains how earth-sheltering mitigates against cold. The 54 F degree temperature of the earth acts as a “blanket” around the house, he says. Includes video of the building process.

Everything about the building is recycled—including the paving stone, which was the floor of old jail cells. The exterior was copper flashing of a mental institution. The window faces south, so that it warms the two-foot-thick concrete floor. Even on a cold day, the floor stays warm from being heated by the sun.
Types of Earth Sheltered Homes
- Earth Sheltered: Dirt covers three exterior sides and the roof (the walls are most often concrete).
- Earth Bermed: Dirt is pushed up against the exterior walls only, and not onto the roof, yet the roof is usually super-insulated.
28 Stunning Earth Sheltered Home Designs
These home designs are not only environmentally friendly, but truly spectacular.
1) Cooper Pedy, Australia
In Coober Pedy, Australia, daytime highs often climb into the 100s and many have taken up residence in abandoned opal mines to beat the heat. Some of the homes can be rented for overnight stays.
2) Outer Hebrides Islands, UK
This earth-sheltered house, which’s almost more of an underground house, is located in the wilds of the Outer Hebrides. It provides a perfect living environment for harsh weather. This home’s support walls are constructed of PolarWall (polystyrene).
3) The Sedum House, North Norfolk, UK
An award winning earth shelter dwelling by Cam Architects. The Sedum House, in Gimingham, North Norfolk, UK, incorporates green technology in the form of ground source heat pumps, photovoltaic panels and a whole house ventilation system. The use of highly insulating ICF in the walls makes for a very low energy use dwelling. Note the sunken room on right.
Side wall of the Sedum House.
4) Earthship Farmstead, Virginia Mountains
Kaplan Thompson Architects did an amazing job with the structure of this building. They used their experience with building “net-zero” homes to create this eco-friendly home.
5) Pinnacle House, New Hampshire
Earth-sheltered Pinnacle House is an award-winning, sustainably-designed home in Lyme, New Hampshire. The home was designed and built by architect Don Metz in 1971, a pioneer in green home design and construction. The north-side of the house is built into the hillside, creating a green roof through the use of earth-sheltered building techniques. The house faces due south, offering passive solar gain and spectacular views from every room.
Pinnacle House interior. How dreamy are those large windows?
6) Underhill, Yorkshire, UK
Underhill, near Holmfirth, Yorkshire, UK. “The first ‘modern’ earth-sheltered house in Britain and the home of its architect Arthur Quarmby, a pioneer of earth-sheltered buildings. The house features earth embankments, turf roof, lots of insulation and a visual impact that not even the pickiest of neighbors could fault.” Best yet, this earth sheltered home features something you don’t often see: skylights.
Earthbag Underground House: Time-Lapse Video
Six months of building this earthbag underground home at a commune in Ecuador, shown in two minutes. First up in the excavation, all done by hand. Next, the earth bags are laid in place. Wooden beams are laid across to form the roof, then metal sheeting laid across the beams.
More sandbags are put in place to form a loft area. Then earth is laid over the lower-roof area, and stucco put around the exposed bags. Very cool (figuratively and literally).
7) Farm in New Zealand
Earth Sheltered Rainbow Valley Farm, New Zealand. The solar design maintains the temperature in the building, creating an escape from the heat while also increasing overall energy savings. The exterior looks similar to that of a conventional home, but the roof is far from ordinary.
8) Earth Sheltered Office, New Jersey
Architect Malcolm Wells built this earth-sheltered office in Cherry Hill, New Jersey—quiet and light-filled even though it’s beneath a meadow and adjacent to a six-lane highway.
9) St-Malo, France

18) Dani Ridge House, Big Sur, California
The gorgeous Dani Ridge House in Big Sur, California by Carver + Schicketanz is tucked into a hillside.
Documentary: Fritz Eisenhofer, Earth-Sheltered Home Pioneer
A Dome in Peka Peka tells the story of Fritz Eisenhofer. He shares his experiences and his knowledge from building earth-sheltered homes. He points out that underground homes need to feel spacious. They can’t be laid out conventionally, or they feel claustrophobic. His solution—to build a dome. This type of structure minimizes the internal structure.
The dome is such a strong form, it’s only 35 mm thick. Stills of the construction process are shown. Eisenhofer narrates the plan of the home, showing where all of the rooms were and their function. The house was built with a swimming pool / garden area. Eisenhofer lived in the home for 20 years…he points out that construction took longer than expected: “Anything new, you can’t rush it.”
19) Two-Story Underground Home, Cumbria
British architect John Bodger built this underground home in Cumbria. The two-story house is burrowed backwards into rock at the site of on an old quarry. See plans and lots more about the project.
20) Earth Shelter, Project Michigan
This building was constructed to keep the windows facing south, protecting them from potential storm damage.

The daytime areas are situated towards the south, the nighttime areas towards the north. In the middle, you find the bathrooms and the connecting stairs to the basement. All the bathrooms get natural light through rooftop windows.
24) Honingham Social Housing, UK
Honingham Earth Sheltered Social Housing. The UK’s first earth-sheltered social housing scheme. “We do not have any heating on at all in the winter and the building still stays at 72 degrees. The light comes in through the full-length windows in winter but in the summer the sun’s heat does not penetrate so you stay cool,” say the owners. And that earth roof is pretty stunning at this angle.
25) Earth Sheltered Home With Natural Swimming Pond
Earth-sheltered home with a conventional facade by Formworks Building. Dig out a pond (raise fish or create a natural swim pond) and place the soil on the house.
Earth sheltered home, as above. This design really allows for the surrounding landscape to do the talking. See the kit and floor plan at: earthshelter.com
26) Mill Valley Cabins
Feldman Architecture used the surrounding redwoods to design a space for the residents that encourages creativity. Talk about some serious privacy in nature!
27) Earth-Sheltered Adobe Home
The facade by Formworks may accommodate any architectural styling of the home owners choosing. Here the structure is a bolted together skeletal steel system which is then sprayed with pressurized concrete, same process as a gunite swimming pool.
28) Earth-Sheltered Home + Umbrella
Use an umbrella to insulate the surrounding soil and increase inner temperatures even more. An umbrella house or PAHS (Passive Annual Heat Storage) home works on the principle that Earth is an ideal thermal mass for storing heat over long time periods. Summer’s heat is absorbed out of the home into the surrounding dry earth, keeping it cool and comfortable. This heat reserve is then conducted back up into the home when winter or extreme temperatures prevail, heat is available even through an entire winter.
To contain the heat, the heat should flow between the earth and the home, rather than the earth and the out-of-doors. You must keep the earth dry around the periphery of the home. The umbrella’s sandwich of polystyrene insulation and polyethylene sheeting (about R-20) insulates a huge mass of surrounding dirt instead of just the house. The lower, inside portion of the home needs but minimal insulation. See John Hait’s book: Passive Annual Heat Storage, Improving the Design of Earth Shelters.
Earth-Sheltered Home Resources
- The Terra-Dome building system is a forming system that helps create a concrete steel reinforced structure in modular form of 24′ x 24′ or 28′ x 28′ (inside measurement). These modules are poured on location and can be arranged in a multitude of configurations. The Terra-Dome module is used for earth-sheltered structures in most cases.
- Sturdy concrete earth sheltered homes are a specialty of Conrad’s Castles Construction in Bastrop, Texas.
- The modular framework of Polarwall makes it easy for earth sheltered home builders to incorporate concrete and steel reinforcement.
- Made from concrete, reinforced steel, and insulating foam, Monolithic Dome Homes are an inexpensive option for above-ground buildings in tornado zones—and are also used for underground homes.
- The idea came from building an igloo—see how Bill Lishman’s idea for an underground home of interconnected igloos was built.
This is an ad for Green Magic Homes, a pre-fab construction concept. The modules are made from resins and composites. They are then assembled—they claim you need no construction experience for assembly. The Hotel Bellandia (see video below), in the Amazon rainforest of Ecuador, was built by Green Magic Homes.

looking for some blueprints for a earth home or a earth sheltered home i really would like to make my first and only house a earth home but cant find a good blueprint
in process of building a large bunker under ground, prepper, but love this idea a lot better. Have seen a program about grey, waste, water with green house that is part of house and you can live off of Grid and have your own food. any ideas or phone numbers who can help me design better?
While discussing earth homes with family. I remember seeing a home featured on MTV Cribs. This home was earth friendly to the point that tub/shower water was drained to the garden. Hot tub was heated with hot rocks. I cant seem to find this home anywhere online. Please help!!!
It was about Sun Ray Kelly. I cannot find the video, it appears to have been erased from the web. Here is a reference to it: ilovecob.com/archive/sunray
looks good
I’ve been trying to contact John Hait, author of the Passive Solar Storage House book, but cannot seem to find a good way to contact him. http://www.earthshelters.com and commonly found phone numbers and email addresses do not work. Does anyone have good contact info?
roofing options
Many of the roof tops have growing gardens, what are the concerns and necessary ingredients to support roof top gardening. I envision water damage.
Hi Jess,
There’s a lot of established methods for waterproofing the roof and safely separating the soil and root systems, but like any roof system, they can fail if done incorrectly or due to other factors. Often it’s done with one or more layers of heavy mil pond liners.

Good to read!
How much are we looking at to build one like the adobe home?
Been looking at Earth Shelter for a few years now and with retirement soon, want to escape the congestion of ever expanding suburbia in the search for as Independent Lifestyle as I can find/create and afford. With annual average temperature at my current location of 69 degrees, earth should be near perfect living condition. A few years back in middle of upper 90s degree summer, I measured temperature 2′ below ground at 82 degrees, 3′ at 81 and 4′ at 79 which is still tolerable.
Every time I mention earth sheltered, someone wants to dismiss with “humidity” which is true of basements 50 years ago but even then some I spent time in were just fine. With proper attention to details I cannot see moisture as a hindrance.
Photo/Attachment:
Hello JJM, I live in an underground home that was built into the Ouachita River bluff here in the Ouachita National Forest in Arkansas. It has north facing windows (on the cliff side) and does not feel like a cave. I do have moisture issues at times, but run fans and dehumidifier to keep moisture at bay. Regardless of how hot it gets here in Arkansas, inside the home has never been above 80 degrees. In the winter, never below 58 or so. I am offering this home as a short term vacation rental for those who want to give underground living a try.
Besides being an amazing underground home, the location here in Mt. Ida Arkansas, quartz crystal capital of the world, is where there are more trees than houses and businesses. This county is 70% national forest. Contact me for rates and availability on staying in this home, or if you have any general questions about my experience living in an underground home for the past 12 years. I can’t imagine a life living any where else but here. There’s no place live home!
nice view connie ! am considering a three sided (in hill) earth shelter in northern arkansas. i assume moisture issues are humidity based ? could you elaborate ? and does surface water runoff from above pose any issues ? thanks
Earthberm with conventional roofing has all the advantages of earth covered house without the added expense & problems of earth covering. Adding layers of waterproof plastic prone to fail (roots can get thru rock. What chance has plastic?) adds a great deal of expense, as does the added concrete….. Earth covered is a disadvantage in winter unless concrete is below freeze line (that’s down 6ft here in WI). My concrete slab/ICF, poured concrete walls with conventional 6″ framing on front wall and conventional truss/metal roof requires no AC in summer (max temp low 90s) and we use only 3.5 cords of wood to heat 2800 sf comfortably in winter (Min temp to -35*F)….Moisture inside depends on humidity outside. Not a big problem, easily handled with a simple dehumidifier in summer & humidifier in winter…. K.I.S.S.
