HiberTec Homes Lower Themselves Underground to Survive Wildfires and Tornadoes

Wildfires and tornadoes destroy thousands of homes across the United States every year. Insurance carriers have begun stepping away from entire regions because the risks keep climbing. Families face the choice of expensive rebuilds or walking away from everything they built. A California company named HiberTec Homes developed a different response. Their houses do not fight the flames or winds at ground level, they simply move out of the way.

From the street, the homes appear to be any typical modern building, with clean lines, large windows, and varied materials that give off a highly contemporary vibe, suitable for a variety of communities. One model opts for a single-story configuration of approximately 1,600 square feet with three bedrooms. The larger variants are two floors tall and around 2,500 or 4,000 square feet. Rather than starting from scratch each time, builders can modify an existing modular home design to operate with this technology.

When danger calls, it all begins with a tap on a smartphone app, as is intended. Part of this patented method is the automatic separation of power, water, and gas lines, ensuring that nothing is left attached when you move the house. Hydraulic columns then step in to support the entire structure and guide it down into the pre-built subsurface vault. Gravity helps with this, and there are some backup power sources as well as a manual winch on standby in case the main power goes out. The journey from street level to safe place takes approximately 15 minutes.

As it descends, a fireproof spray is released around the property, adding to the level of protection. When the house reaches the end of its journey, a large heavy-duty cover emerges, sealing the vault with some highly fire-resistant material. The house and all of its belongings are now safely tucked away below ground level, protected from temperatures that can exceed 2,000 degrees Fahrenheit and last for days.

The underground vault is designed to withstand conditions that would be too extreme for standard fireproof construction. Some surface materials may be able to withstand brief exposure to temperatures as high as 850 degrees, but this technology ensures that the house never has to encounter such temperatures in the first place. Tornado-force winds and their accompanying debris lose their objective the moment the house is underground. Homeowners continue to follow evacuation orders because the vault is designed to protect the property, not the people inside, and they may return later to find everything completely intact.

The starting price for this system is roughly $1,200 per square foot, before you even consider the excavation and site preparation charges, which will be slightly more. Even the smallest model will cost over $2 million or more, depending on your location and soil conditions. As production scales up, the company intends to reduce the cost to around $500 per square foot. To get this system to work, you need stable ground and a water table that is not too high. Unfortunately, most existing homes are unsuitable since the vault and associated hydraulics must be incorporated into the foundation from the beginning.

There are three utility patents that cover the basic ideas: one for moving the structure, one for the retractable cover system, and one for safely disconnecting and reconnecting utilities. The entire creation process took over 5 years, with a team of engineers and architects on board. Later on, they intend to build a full-scale prototype near Los Angeles to demonstrate the entire system in operation under real-world conditions.
