Monolithic Constructors, Inc.

About this Place

We are the original Monolithic Dome construction company.
The first Monolithic Dome ever constructed was built by David, Barry and Randy South in April of 1976 in the small town of Shelley, Idaho. David and Barry (Randy was too young at the time) had been insulating potato storages all over the northwest for years, so the choice for the first Monolithic Dome to be a 105-feet diameter by 35-feet tall potato storage seemed natural. They then patented the process and began marketing and building bulk storages in Idaho and up and down the Mississippi River.

In 1978, the brothers built the first Monolithic Dome House for their mother, Marjorie South. In 1979, David and his wife, Judy, built Cliffdome for their large family of 10 kids.

Cliffdome was built by David and Judy South in 1979, primarily to illustrate the Monolithic Dome’s potential as the perfect structure for a variety of uses. The family gave tours of their 8,000 square foot home regularly.
Cliffdome was a huge home with 8,000 square feet of living space and a 1,500-square-foot attic. Many thought David had built the large house because he had so many kids, but that was not the case. David built Cliffdome to show people that the Monolithic Dome could be used for any purpose.

David knew Monolithic Domes would be ideal for schools, churches, resorts, fire stations, municipal complexes, military compounds and more—not just storages and a few houses. To that end, Monolithic Constructors, Inc. was formed in 1980, and the three brothers started changing the world, one dome at a time.
