The study set is intended for early-stage planning, such as obtaining quotes, searching for land, and consulting with local builders and permitting authorities. However, the study set cannot be used for actual construction, and we do not grant a license to build our designs with a study set. The building plans, on the other hand, is designed for obtaining detailed cost estimates, building permits, and actual construction. It includes comprehensive building details and a material list, simplifying the building process and permitting procedures. The building plans package comes with a single building license.
