This structure is an interesting example of the complications I occasionally encounter with identifications. The sides of the building, unlike the plank front, are board-and-batten, and there’s no sign of a chimney, but I think the sides were updated.

The lack of a chimney initially led me to think this was a barn, but the door placement and original shake roof indicate this was a tenant house, or perhaps a kitchen. It has obviously been purposefully preserved as an important landmark of the historic farm on which it’s located.
