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.
