History and architectural features
This farm has three contributing buildings and one contributing structure. They are the miller's house, a one-and-one-half-story, stone-and-frame grist mill, which was erected in 1805, a stone-and-frame bank barn, which was built circa 1840 and the head and tail races.

The house is a two-and-one-half-story, five-bay, banked, fieldstone dwelling with a gable roof. The foundation in the western section was built sometime around 1725 to support a log dwelling. It was expanded with the present eastern section in 1735; the log section was replaced circa 1780.

A two-story, two-bay annex was built between 1935 and 1940, and was expanded in 1965. A shed-roofed addition was built to the north in 1990.

It was added to the National Register of Historic Places in 1990.
