It was built about 1886, and has two sections: a $2 1/2$-story rectangular, brick main block and a two-story rear ell. It features a hip-on-mansard roof and two one-story, brick polygonal bays. It combines features of the Italianate and French Second Empire styles. Also on the property are the ruins of a brick dairy, the cement foundations of a silo, and the stone foundations of another outbuilding.

It was listed on the National Register of Historic Places in 2002.
