A Cold Study Follow Up The Eckers’ Monolithic Dome home in Galax, VA is an oblate elipse on a 2’ stemwall and has a 50’ diameter. Its single story with loft provides 2675 square feet of living space. To outfit their home, the Eckers used universal design products that can be comfortably used by virtually anyone at any stage of life. This data clearly illustrates that domes typically use 1/2 the energy or less to heat.
