Eco-Friendly 3D-Printed Home Made from Soil

A groundbreaking new residence in Japan is attracting attention and revolutionizing the construction industry. The Lib Earth House Model B, a single-story home, was constructed using 3D-printing technology and a soil-based mixture instead of the traditional concrete. This innovative approach combines technology with nature in a sustainable way that has the potential to transform the way homes are built globally.

The home, located in Yamaga, Kumamoto Prefecture, was built by a collaboration between Lib Work Co., Arup, and 3D-printing firm WASP. Instead of using cement, the team developed a new material made from earth, lime, and natural fibers. These materials are renewable, readily available, and environmentally friendly.

During the construction process, WASP’s 3D printer was used to layer the soil-based mixture to create the curved walls and ribbed texture of the home. Once the structure was complete, human workers installed the windows, doors, and roof to finalize the build.

Inside, the home boasts a modern and bright feel. Large windows flood the rooms with natural light, while clean lines enhance the overall space. The flat roof and textured walls subtly showcase the home’s 3D-printed origins.

In addition to being eco-friendly, this sustainable 3D-printed home is off-grid and fully connected. It utilizes solar panels and Tesla’s Powerwall battery to power everything from lighting and air conditioning to a smart bath, all of which can be controlled through a smartphone or voice command. Sensors integrated into the structure will monitor its performance over time, tracking aspects such as insulation and humidity to gather insights that can enhance future designs and address questions about durability.

The Lib Earth House serves as a prototype for a more environmentally conscious way of living. By avoiding concrete and focusing on materials that can return to the earth, the home helps reduce landfill waste and carbon emissions. For individuals interested in environmental conservation, energy efficiency, and cutting-edge living, this project offers a glimpse into the future of residential housing. Lib Work aims to deliver 10,000 units by 2040, with pre-orders set to begin in August. While currently only available in Japan, there are plans for expansion in the future.

From its construction using soil to its innovative design, the Lib Earth House Model B showcases that sustainable housing can be both comfortable and stylish. Its incorporation of smart energy systems and eco-friendly design sets a new benchmark for the future of housing, addressing both climate and housing challenges simultaneously.
