4 Foot Gridbeam Box

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, and tools with no special skills or tools required.

It’s perfect for prototyping, sustainable design, and reuse, empowering people to create endlessly reconfigurable and repairable systems.
