You mentioning North Georgia made me think of my consulting on a Structural Concrete Insulated Panel (SCIP) home in the Dawsonville, GA area that included a basement. Gulf Concrete Technology of Long Beach, Mississippi supplied the SCIPs, mortar and equipment, http://www.gctm2.com/ If interested in using SCIPs, contact Scott Miller, Technical Adviser/Sales, (904) 742-4175,
[email protected] Joe Martin, Architect, Chattanooga, TN designed the home. Joe was a former architectural student of mine when I taught at the Auburn University School of Architecture several years ago.
