David, Barry and Randy South switched on the inflator fans to construct the first Monolithic Dome in April 1976. It was for a potato storage in Shelley, Idaho — 105-feet diameter by 35-feet tall, which was pretty ambitious for their first dome. It changed their lives. They patented the process and started changing the world, one dome at a time.

Today, there are Monolithic Domes throughout the United States and the world — from the Arctic to the tropics — used for schools, storages, churches, homes, gymnasiums, safe rooms and much more. There are domes as small as 8-feet to over 340-feet diameter with engineering for even larger structures. … read more

The offer for a commemorative plaque always arrives first when a patent is granted. The plaque company usually beats the patent office by a day or two. It’s an effective marketing strategy; after all, Monolithic has five of these plaques. Now there will be six. A couple of days later, the official notice from the United States Patent and Trademark office arrives. Monolithic Constructors, Inc., is granted patent number 10,400,462 for the “Transverse Span Airform Structure.” … read more

We are sad to announce the passing of David Barney South Sr. — husband, father, entrepreneur, and inventor. David was married to the late Judy Lynne South (née Bates), and they raised nine children together. He co-invented the Monolithic Dome with his brothers, and they built a new construction industry. … read more

An oblate ellipsoid is a common shape for Monolithic Domes. The foundation is circular, but the profile is elliptically shaped. It creates higher “walls” around the outside of the dome, giving more headroom. … read more

Ohio is probably not the first State people think of when discussing tornadoes. Oklahoma or Kansas are more likely to provoke visions of violent skies and Dorothy running for the storm cellar. Yet, 36 tornadoes already struck Ohio this year — double the total tornadoes in 2018. “We are not dealing with a theoretical hazard,” said Sean Miller at the open house of the new Delaware State Park Tornado Shelter. “This is a very realistic hazard … and campers are vulnerable.” … read more

The Oktibbeha County Community Safe Room is a Monolithic Dome built near McKee Park and the Starkville Sportsplex in Starville, Mississippi. The structure is a FEMA P-361 rated safe room that can protect 1,500 people during a severe storm. Planning for the tornado shelter began in 2014 after “a tornado outbreak ravaged Mississippi, including an EF-4 tornado that devastated Louisville.” … read more
