Grid Beam is a modular, open-source building system inspired by Ken Isaacs’ Living Structures. Made up of standardized, perforated beams that connect using simple nuts and bolts, Grid Beam allows anyone to build structures, furniture, vehicles, think of it as an adult-sized Erector Set—ideal for kids, makers, tinkerers, educators, and inventors. It’s perfect for prototyping, and reusing empowering people to create endlessly reconfigurable and repairable systems.
