Mono-Material Wood Wall is a new approach to sustainable construction for homes. The system achieves structural stability, enclosure, and high insulation values using solid timber, a natural, renewable and recyclable material. The system uses a computational model that gives architects the ability to rapidly design expressive forms that are instantly translated into machine code for automated fabrication. Combining traditional wood craft joinery with contemporary digital fabrication adds functionality to wood material, bringing the log cabin into the forefront of 21st century architecture.
