Woman single-handedly builds an underground wooden house in just 32 days, lives off the power grid, and creates a self-sufficient refuge hidden in nature.
The project begins in a raw and direct way: choosing the exact spot on the land and manually excavating the soil. Without machines, backhoes, or external support, the woman uses only simple tools to open the space that would house the underground house. The images show the gradual progress of the hole, with walls carefully carved to ensure stability and natural drainage, something essential in buried constructions. The rectangular shape of the opening already foreshadows the internal organization of the shelter, demonstrating that nothing there is improvised.
The underground house structure uses wooden logs and traditional techniques.

With the excavation complete, the structural phase begins. Wooden logs are cut, debarked, and positioned vertically along the walls of the hole, acting as retaining pillars. On top of them, horizontal beams form a solid framework capable of supporting the weight of the earth that will later cover the roof.

The technique harks back to ancient methods of underground construction used for centuries in different regions of the world, especially in forested areas where wood is abundant and resistant when properly treated.

Interior wooden walls create natural thermal insulation.
As the structure progresses, the interior walls begin to take shape with wooden planks fitted together one by one. The finish reveals an aesthetic care that goes beyond functionality.
The combination of woods with different tones creates a welcoming look, while the surrounding soil itself acts as a natural thermal insulator, maintaining a stable internal temperature even with external climate variations.

This is one of the great advantages of underground houses: thermal comfort without consuming electricity.
The top closure is one of the most critical stages of the project. On top of the beam structure, the construction company installs planks, a waterproof protective layer, and then replaces the soil removed during excavation.

The result is a roof completely integrated into the environment, practically invisible when viewed from a distance. The vegetation is replanted on top, causing the house to disappear into the landscape, creating a hidden, silent, and protected refuge.
Even without a connection to the electrical grid, the interior space is functional. Lighting is provided by lanterns and low-energy lights, while the intelligent use of natural ventilation ensures air circulation.
The images show moments of everyday use of the shelter, such as simple meals, rest, and organizing the interior space. Everything is designed for the essentials, without excess, reinforcing the concept of self-sufficient and sustainable living.
Sustainable construction showcases a real alternative for off-grid housing.
The project is noteworthy not only for its speed—just 32 days—but also for its feasibility. The underground house uses local materials, reduces environmental impact, eliminates the need for concrete, and virtually eliminates the need for artificial climate control.

At a time when the cost of traditional housing is rising and the search for off-grid solutions is increasing, this type of construction emerges as a real alternative, especially in rural and forested areas.
A hidden haven that combines technique, resilience, and simplicity.
More than just a buried cabin, the construction represents a lifestyle choice. Each step of the process reveals physical resilience, practical knowledge, and a direct connection with the natural environment.
In the end, what emerges is not just a house, but a silent, self-sufficient refuge integrated with nature, capable of functioning far from civilization without sacrificing essential comforts.
