David, Barry and Randy South switched on the inflator fans to construct the first Monolithic Dome in April 1976.

Back in 2020, Jo King listed her Hawaiian home for sale. Needless to say, selling a home during a pandemic proved more than a little challenging. Instead, she pulled it from the market. Now she thinks it’s time to try again. Her Monolithic Dome home is in one of the most beautiful settings we have ever seen — on the island of Kauai. … read more

Twenty years ago, the school board in Avalon, Texas, broke ground on a new Monolithic Dome gymnasium. It would be more than just a place for playing ball, it became a classroom, concert hall, community center, and — when necessary — a storm shelter.
