Earth sheltered home plans became popular in the mid 1970’s when energy efficiency emerged as a popular social and economic concern. Prior to that time however, Earth Homes
had been around for centuries. Among the advantages of an underground home are energy savings and superior safety from damaging storms such as tornados. If an earth shelter or underground house is constructed properly it is also very earth friendly, in terms of material usage and energy consumption. Earth berm houses are one of the most environmentally or eco-friendly homes available.
