## History and architectural features

The original building was built in 1839, and was more than doubled in size in 1850. It was originally a two-and-one-half-story, rectangular, brick building with gable roof that was designed in a vernacular, Federal style. The 1850 expansion raised and flattened the original roofline, and added a three-bay, three-story brick addition to the east side. An old brownstone addition pre-dates the 1839 building.

It was added to the National Register of Historic Places in 1985.
