Earth Sheltered Homes

earth sheltered him honingham
“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.

The earth sheltered home uses the ground as an insulating blanket which 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. 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 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.

The 2 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.

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).

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

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

earth sheltered home

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 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 speciality 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.

  2. 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?

  3. 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!!!

  4. 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

  5. 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?

  6. 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.
