The Living room area of this home may sometimes almost seem alive ... a living room. The indoor pool remains at room temperature. Changing patterns of light mark out the time of day and seasons of the year.
Left to itself, the room temperature will remain at a constant near 70 degrees F., year round. The temperature can also be fine-tuned without use of an outside commercial energy source by the opening and closing of air tubes that penetrate the surrounding soil. The rainbow colored, cantilevered panels are portals  to other areas of the house.

A Liberty Home (and other-use structures) are formed in the earth, using mounded and sculpted earth as a reverse mold as illustrated in this animation. Shot-crete or regular poured Portland cement mix is applied over the earthen hemi-spherical mound. After setting and curing of the concrete, the soil is removed from under the reinforced shell and placed on top. More earth is bermed over the structure. then the shelter and surrounding earth bank is covered with an umbrella comprised of insulation and polyethylene sheeting extending beyond the perimeter of the structure 20'. The insulating, water-shedding, 'umbrella' is itself covered with more earth sufficient to support growth of vegetation for ground-cover and soil retention.  Again, this method of insulating and waterproofing the structure, while both easier and less expensive than standard practices, utilizes the heat storing capacity of the earth instead of thwarting it as occurs when insulation is applied directly to the structure itself, allowing the surrounding earth to remain cool and wet.  If heavy equipment is not available or affordable, it is feasible that the entire form can be dug and shaped with only a shovel and other small hand tools.  It is surprising how much dirt can be moved by one healthy person in a short period of time. .. even by an aging, out-of-shape codger such as myself. The reverse mold for my 20' diameter model was made in only twelve hours of hand-digging. Designing several smaller inter-linked domed rooms instead of a single larger diameter area, divided into rooms, makes hand digging much more feasible.  A 'Bob-Cat' type back-hoe/front-end loader or excavator, a powered conveyor belt, or for larger buildings, larger earth moving equipment, obviously can get the job done much quicker and with less muscle power. Many circumstances today and in the future can prove labor-intensive activity a positive benefit, rather than a burden.  This method can allow otherwise unemployed persons to build their own homes and help others build theirs. There are few localities with special soil structure or water table issues where provision cannot be made to allow such a structure to be built. Earth formed and sheltered buildings can be constructed completely above ground by mounding earth and other materials for use as a form, and then bermed. They can be, designed to be built partially below grade, partially above ...  or completely underground.  The greatest negative now is the requirement for Portland Cement and iron reinforcement materials such as rebar and welded wire mesh. These materials are very costly in terms of the environment and the atmosphere because of the CO2 emissions in manufacture  and transportation. Someday soon, hopefully these materials too can be replaced with structurally safe, more 'natural' local materials. Considering the low maintenance and durability these structures, these environmental costs amortized over the long term are probably less than standard construction methods and material. Until other ways are perfected to support the weight of the soil, to the author, a real necessity for the days ahead, using concrete may be the only safe way to build underground or earth bermed structures.  Any other successful safe ways to support this much soil, I would be very interested in learning about A non polluting energy source to produce the 2000+ degree temps required for Portland cement production will be a great boon to planet earth and it's inhabitants, for sure, when that day comes. For temporary structures, wood and metal supports and walls can be used for expediency, but are not ideal.  Earth and sand-filled bags, Nadir styled construction holds some promise as well, though not as quickly built, or with as much potential for diversity of design . Earth-forming can be used to create buildings of any size and most any purpose. The method particularly lends itself to inexpensive storm shelters and emergency protection for any catastrophic circumstance, including nuclear blast and fall out. The buildings can be hidden, undetectable to passers-by.  Entire communities can be designed, with environment friendly structures for shops, common areas, emergency shelters, workshops, and storage facilities. These structures can be well lighted, and ventilated ... artistically designed , satisfying and pleasing to the eye, and made to blend harmoniously with the environment. 'Underground' does not necessarily mean cave-like.  From root-cellars, saunas, special livestock shelters, from plain domed shapes to free-form sculpted rooms ... shopping malls? churches? all earth-formed and earth-sheltered at lowest cost available. "Dirt-cheap" housing, healthful, comfortable, and aesthetically pleasing should be a reality for anyone who needs and desires it. Gifts from the Creator: Earth, the Sun and all the laws of nature, available for the responsible use and taking. All other creatures seemed to have accomplished this. Why can't we humans? Earth sheltered, storms can blow, temperature records may be broken, earthquakes can shake, fires rage. but being in such a earth-sheltered home may be the safest place to be in the chaotic days ahead. With the use of such simple, age-proven principles, there may still be life left to carry on, and standing models for the life to follow.
