Plan Packages: Each set of construction documents includes detailed, dimensioned floor plans, basic electric layouts, structural information, cross sections, roof plans, cabinet layouts and elevations, as well as general specifications. They contain virtually all of the information required to construct your home. The typical plan set does not include any plumbing, heating or air conditioning drawings due to the wide variety of local codes and climatic conditions. These details and specifications are easily obtained from your builder, contractor, and/or local suppliers.
