Earth-sheltered homes are structures built into the ground or covered with soil, providing natural insulation and protection from the elements. These homes often use the earth's thermal mass to maintain a stable indoor temperature, reducing the need for heating and cooling. These designs can be energy-efficient and environmentally friendly, as they blend into the landscape and minimize visual impact. Additionally, earth-sheltered homes can be constructed using various materials, including concrete, wood, and straw bales, allowing for creative and sustainable building options.
