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

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

MIT students hacked the MIT Great Dome by turning it into Captain America’s shield in honor of Avengers: Endgame. Students carefully covered the dome with a fabric “shield” on Saturday, April 27, 2019, during the opening weekend of Endgame. MIT sophomore Raymond Huffman shot a drone video of the shield on Sunday morning. By Monday, the shield was taken down. … read more

There’s a palpable “wow factor” to this home. Surrounded by a sense of pleasure and possibility, the structural roots of this monolithic dome home define its genius. The brainchild of aeronautical engineer Chris Barnes, the dome was built intentionally to be a showplace for modern design, energy efficiency, optimism and individuality. … read more

Dome at the crossroads

Thanks to a generous, anonymous donation the community of Hansen, Idaho, has a new gymnasium. The Hansen School District owns the 120-foot diameter monolithic dome but shares it with the city. “This is a unique facility,” said Superintendent David Carson at Friday’s open house. “It’s a community school district partnership. Both entities will be able to use it — a lot.” … read more
