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

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

Spherical dome calculator conceptual sketch

Eighteen years ago, I wrote the first dome calculator for our website. I’d used the formulas before in spreadsheets, pattern programs, and even a script for the Palm Pilot. Writing the little program in the new web language of Javascript was fun. We still use it today, but it’s showing its age. The old calculator doesn’t work well on phones, and it has a dated, turn-of-the-millennium style. We have a new website; it is time for a new calculator. … read more

Today’s Throwback Thursday is a bit different as we look to the past and the future in Johnson Creek, Wisconsin. In 2016 the Johnson Creek School District opened a five-dome school to serve as the combined middle and high school. The small district of 750 students was dealing with old school buildings plus a hodgepodge of additions and portable classrooms. The maintenance costs were increasing and they needed something new. They tried several times to pass a bond to build a conventional school, but each time the voters rejected it. So they sought for a more innovative, affordable solution and found the Monolithic Dome. … read more

Whoever buys Jo King’s Hawaiian dome will buy so much more than a home. They’re buying a dream. The dome has a lot to offer, starting with breath-taking views. Snuggled on an acre of land in the Waimea Valley on Kauai, it’s surrounded by an abundance of history and natural beauty. The open floor plan offers two bedrooms and two and a half baths upstairs with another bath as well as two outdoor showers downstairs, all covering about 1,700 square feet. Painted coconut palms adorn the concrete walls, and a large lanai takes full advantage of the scenery. … read more

Monolithic Dome workshop graduation photo

We live with hope for a better future, yet we need to recognize the realities of today. COVID-19 cases are surging in Texas and across the US. There is no reason to believe the coronavirus pandemic will end anytime soon. We must accept that this is our new “normal” and plan accordingly. To that end, we are canceling the Fall 2020 Monolithic Dome Builders Workshop. … read more

Lincoln County Farm Center

Today’s Throwback Thursday is the Lincoln County Farm Center on US Route 66 in Chandler, Oklahoma. It’s home to the first Monolithic Dome fertilizer storage project — built more than 40 years ago in 1978. In 2011, the storage dome was covered with stainless steel and in 2015 they built a large, Monolithic Dome ranch store. … read more
