Higgins Incorporated of New Orleans patented Thermo-Con Concrete and sought to promote its use as a building material throughout the southern United States, as well as the Caribbean, South America, and parts of the South Pacific region. In 1946, the company built a Thermo-Namel demonstration house at its Industrial Canal plant, and one year later followed with the Thermo-Con Demonstration Houses erected on the corner of North Broad Avenue and Havana Street. Other Thermo-Con residences quickly followed, and included a cluster on Havana Street, ones on Althea and Hydrangea Lanes in Lake Vista, and one on Vicksburg Street between Harrison Avenue and Bragg Street. A developer in Atlanta used the material to build a 104-apartment complex in North Buckhead, and another developer planned to create 200 3-bedroom houses in Pass Christian Heights, Mississippi. Thermo-Con's use went beyond residential architecture: fire walls in Fort Worth, Texas; USAF buildings at White Sands, New Mexico; and warm-up pads for the USAF at Andrews and McChord Air Force Bases.
