About These Cooperative Extension Plans:  These plans were developed over many years by engineers at U.S. Land Grant universities. They are generally older plans that need to be revised for today's construction methods, codes and standards. They provide design ideas and conceptual information for planning purposes. The plans were prepared through the USDA Cooperative Farm Buildings Plan Exchange.

Buildings must resist various forces from snow, wind, earthquake and use. They also must adhere to local building and zoning codes. A local building inspector, engineer, building supplier, or building contractor can help you determine what is a safe and legal building for your area.
