Lib Earth House
Redefining the Home:
Creating the Future of Living
We're here to challenge conventions in homebuilding.
We have constantly sought to break through established ideas—now, we introduce a new era of housing by fusing advanced technology and natural materials.
We pursue both environmental responsibility and solutions to social issues, offering sustainable living for all.
Furthermore, by utilizing AI from design to construction, we are aiming for the world’s first fully automated homebuilding.

Advanced Technology

Natural Materials
◇ Main materials: soil and natural elements
We have successfully developed a sustainable earthen wall made entirely of soil and natural ingredients, without any cement. Lib Earth House model B is five times stronger than previous models and drastically reduces CO₂ emissions. This is not just a house—it's a challenge to rethink how we live. The underlying innovation is now patent pending, protecting its value as a unique advancement in architecture.
Health Monitoring
◇ Next-generation homes that watch over your health
Sensors embedded within the walls continuously monitor temperature and humidity, detecting signs of condensation or deterioration. The house manages its own condition with an “internal wall condensation monitoring system.” Air conditioning and lighting can be operated remotely, and facial recognition at the entrance provides keyless security—redefining the quality of daily life with technology.
Circular Economy
◇ Toward a circular, self-sustaining lifestyle
Our off-grid system uses Tesla Powerwall and solar panels to generate and store electricity, enabling self-sufficiency and energy circulation at home. This home, rooted in the philosophy of a circular economy, offers a sustainable lifestyle that is gentle on the environment.
Breathing Design
◇ Breathing homes, connected with nature
With living areas, bedrooms, wet spaces, and a courtyard designed for natural light and breeze, the home invites nature’s rhythms indoors. This gentle, harmonious design enriches daily life, creating comfort through balance with the environment.
The Story Behind Our 3D Printed House

Building the Future from Earth

This is a story of a quiet revolution, born from a simple question.

“Is the way we build homes today truly fit for this era?”
In Kumamoto, supported for years by skilled artisans, we paused to reflect. Despite natural disasters, labor shortages, and rising costs, we kept building homes the same way. Was this truly the future of living?

That was the start of our challenge: to build homes from soil.
The oldest and most familiar of materials, combined with advanced technology never before tried—our mission was to create homes that didn’t yet exist in the world. That is the LibWork 3D Printer House Project.

We searched for answers across the globe, collaborating with robotics engineers and Italian 3D printer manufacturers. With repeated trial and error, we built “homes of earth” from scratch—uncharted territory where tradition and convention offered no guide.

In 2024, “Lib Earth House model A” was born. Then, in July 2025, the approximately 100㎡ “Lib Earth House model B” was completed.

A small house, cloaked in the color of the earth—built not just with “technology” or “efficiency,” but with passion.

We aim for a new style of living: sustainable, comfortable, beautiful homes realized with technology that gently supports each dream.
Through this project, we ask people in Japan and around the world—
“Is your home truly ready for the coming era?”
LibWork is starting the future of homebuilding—from the earth, today.

FUTURE INNOVATIONS
Beyond convention—a new form of living.
AI, 3D Printing, NFTs—revolutionizing homes through technology.
AI Full Auto Build
◇ Pioneering the world’s first fully AI-automated homebuilding
We have launched a project to realize the world’s first fully automated homebuilding by AI. Integrating generative AI into both design and construction, we are building a seamless automation system—from plan to print. This will create a more efficient and sustainable way of building homes, leading the housing industry into a new era.
NFT Asset
◇ Turning design data into assets: NFT and BTC-based 3D printed homes
For Lib Earth House, we are envisioning a new sales model—NFT-izing the design data and accepting Bitcoin payments. This ensures transparency in ownership and history, establishing a new global standard for home transactions. Each house is a unique asset, able to travel the world.
