The Monolithic Dome Institute (MDI) advances the construction of the Monolithic Dome — a super insulated, steel reinforced, thin-shell concrete structure. Built worldwide for residential, commercial, and industrial uses the Monolithic Dome is beautiful, energy efficient, green, and strong.

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

Before the sun came up on a cold December morning, the crew turned on the four large blowers that were to inflate the structure. They said it should take about three hours to completely inflate, which gave my team plenty of time to set up the four time-lapse cameras, a drone, and several ground video cameras. Next thing we knew, the roof was up within minutes, including that big heavy ring. We were not ready! Think about this, an entire weather-sealed, full-size gymnasium was completely standing in about 45 minutes! … read more

Congressman Kevin Brady speaks about FEMA grant

Several Monolithic Dome safe rooms recently made it into the news. A nearly completed safe room in Mississippi was used for the first time as a large storm approached the community. Tuscaloosa, Alabama, opened its new community center and tornado shelter dome. A first responder safe room grant awarded to Covenant Christian School in Texas. And a Tennessee high school applies for FEMA grant for a combined gymnasium and safe room. … 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

A dome hotel is opening in Costa Rica this December. The IGLOO Beach Lodge is a series of individual Monolithic Domes surrounding a swimming pool. Each dome is a room with one or two beds with a huge windowed entryway. Vines will grow over the shells to complete what is billed as a luxury eco-tourism accommodation. … read more

The tent is up, chairs placed underneath, tables set up nearby, grills are hot, steaks are ready, and pickups are parking on the grassy field. Time again for the annual Jackson Farmers, Inc. open house where farmers see demonstration crops, listen to sales presentations, eat steak, drink beer, and — this time — inspect their new Monolithic Dome fertilizer blend plant. … read more

Delaware State Park Tornado Shelter

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

Architect Jason Elliott Purdy designed the “spaceship” house for Clarence and Louise Lederhos who constructed the dome in 1978. “For some reason, I always wanted to live in a round house,” said Louise Lederhos in an interview. “But it was the energy efficiency that drew us to this design.” In 2016, they sold their home. Today, it’s on the market again. … read more
