Ep 3. Idaho Underground Home

Building Off the Grid season 12 episode 3 is titled "Idaho Underground Home" and features a breathtaking project in which a couple, Marc and Sarah, build a unique and sustainable home in the remote wilderness of Idaho.

The episode begins with Marc and Sarah sharing their vision for an underground home that would be both eco-friendly and capable of making use of solar power. The site they've chosen for their project is in a mountainous area with rocky terrain and a challenging climate. They need to work with the natural landscape in order to create a sustainable living space that blends seamlessly into the surrounding environment.

The first step of their journey involves excavating the site and clearing the land to make way for the home. This task proves to be challenging given the rough terrain and limited resources available. But through hard work and determination, the couple manages to dig out the foundation and prepare the site for building.

The next step involves lining the foundation with a layer of waterproof fabric in order to protect the home from moisture and dampness. This is followed by the construction of the exterior walls using insulated concrete forms, which are known for their excellent insulation properties and solid structure.

Once the foundation and walls are in place, the next step is to create the roof. Marc and Sarah choose to build a "green roof", which is a living roof that's capable of providing insulation, reducing energy costs, and producing fresh herbs, fruits, and vegetables.

After the roof is installed, the team begins to work on the interior of the home. They install a geothermal heating and cooling system that uses natural heat from the earth to regulate the temperature inside the home. They also install a solar panel array that generates all the electricity the home will need.

Finally, they begin to decorate the interior of the home, putting their own personal touches on each room. They choose natural materials such as wood and stone to decorate the space, creating a warm and welcoming atmosphere.

Throughout the episode, the couple faces numerous challenges, from working in extreme weather conditions to dealing with the natural hazards in the area. However, they remain determined to see their vision through to the end.

Building Off the Grid season 12 episode 3 is a captivating and inspiring look at the ingenuity and resourcefulness of these two individuals as they work to create a unique and sustainable living space in the Idaho wilderness. The episode is must-see television for anyone interested in sustainable living, eco-friendly architecture, and innovative construction techniques.
