Stark's Cabin is a single-pen, one-and-one-half-story log cabin, approximately 18 feet by 18 feet, with dovetail notching and a cut-stone chimney. Its construction date is unknown but is believed to fall during the first phase of Cumberland Furnace. Without its front porch and shed-frame addition, it reflects the many cabins that once formed part of Cumberland Furnace when it was an iron plantation.
