Even though it has newer front doors, this structure fits the “shotgun” profile associated with many stores and commissaries in late-19th- and early-20th-century Georgia. The style was also commonly used for warehouses. Until I learn more, I’m identifying it as a store.
I’ve heard them referred to as stagecoach stops. Later most became yesteryears version of a convenience store. They usually had the overhang to pull under, a sign post out front and a wood stove chimney in the back. The ruins of one is on the front yard of my daughters property in Lexington.
