The second earth-sheltered home by Massachusetts underground home legend John Barnard, Ecology II takes a much different approach than its predecessor. Instead of a pit/atrium style underground home layout, this design is more reminiscent of the terra-dome(tm) form style.
This home truly fits the bill of an “underground” home, with all access from a below-ground-level central atrium. John Barnard, a legend and veteran of the underground home field designed this underground home (in a series of many) to be built by contractors outside of the underground home field. A central atrium lets light in through all facings, eliminating the need to be faced in a specific direction as in some south-facing designs.
