With the rising costs, scarcity of materials, and greater construction requirements for regular tobacco barns, the concept of a lower cost but functionally sound tobacco curing facility with partial or no sidewall closure has been developed into a blueprint plan shown in Figure 1. The plan can be built and used now with partial sidewalls and enclosed more completely later if desired.
