Board Lock is a DIY home builder that allows customers to construct their own small home using sustainable materials. This construction method allows for structural wall systems to be assembled with little-to-no prior construction knowledge. This allows the customer to build their own shed, garage, or small home. The system consists of small, prefabricated vertical and horizontal pieces that lock together with dovetail joints, rather than the typical nails, screws, or bolts. The only tools required are a mallet/hammer, a wrench, and a ladder.
