The Monolithic Dome Institute is a Texas-based company that has been building domes for personal and public use for decades, explains CBS News. Dome Incorporated in Minnesota also builds domes. Concrete domes are designed to be one of the most energy-efficient, protective homes on the market. They can withstand Category 5 hurricanes, F5 tornadoes and wildfires. Despite the economical cost of building these homes, they remain an oddity in otherwise traditional neighborhoods, making them a difficult sell, as of 2015.

Domes can be designed for churches, homes, schools, stadiums and cabins. As of 2015, state-of-the-art popped-up concrete dome construction relies heavily on inflatable shells, according to gizmag.
