The Leaphart/Harman House on the grounds of the museum was originally located near Corley Mill Road and US 378 east of Lexington. It was constructed about 1800 and owned by George Leaphart, a farmer and sawmill owner.

It was intially built as 5 rooms. The house was enlarged with 2 more rooms on the east end, built entirely of heart yellow pine, The wooden structure of the house clearly shows the hand planed boards cut with a water powered vertical saw, probably at the Leaphart’s own saw mills.
