Our latest collaboration with Lib Work introduces the groundbreaking Lib Earth House Model B—a full-scale residential prototype that marries 3D-printed soil walls with widely adopted timber frames. This innovative approach demonstrates how natural materials and digital fabrication can create environmentally conscious homes that meet modern living standards. Spanning approximately 100m², Model B showcases our hybrid construction method, merging advanced 3D printing technology with mainstream Japanese wooden housing techniques. The design features self-supporting soil walls reaching 3m in height, deep eaves, and a cluster-type layout that seamlessly connects living spaces with nature. By optimising soil-based materials and printing paths, we have achieved both structural integrity and aesthetic freedom. This milestone project opens new possibilities for sustainable architecture. By combining earth’s natural properties with digital innovation, we are creating homes that not only reduce environmental impact but also provide thermal comfort. The success of Model B proves that sustainable construction can be both practical and architecturally expressive, setting a new standard for eco-conscious residential design.
