18th century to early 19th century stone residential architecture in Greene County. Original forms and many original materials survive or are clearly discernible. Spatial divisions and room uses have changed over time and help to illustrate how the building was adapted to meet the needs of its occupants over more than a century. Smokehouse The smokehouse, located northeast of the residence, is a tall stone structure surmounted by a wood-shingle gable roof with overhanging eaves. There is a vertical-board wood door with iron hardware in the south wall and small rectangular openings in the gables. The smokehouse is believed to date to the late 18th century or early 19th century. Garage The three-car garage, constructed in 1980, is a rectangular (20' by 32') wood-frame building with a standing-seem metal gable roof surmounted by a small cupola with weathervane. It sits on a concrete slab and features novelty siding. Shed The shed is a small, square (8' by 8'), wood-frame building with novelty siding and a gable roof with overhanging eaves. There is a vertical-board wood door in the north elevation and a small vent in the gable. The shed occupies the site of an original milk house.

The six-by-two-bay, -story building was constructed in two stages by Jeremiah Rushmore; a descendant of English Quakers from Long Island, whose family owned the property for more than a century. Although the exact building date is not known, tax records and construction details indicate a late 18th-century construction date or the earlier (western) half, while Rushmore's will confirms that the later (eastern) addition was constructed before his death in 1828. The building underwent renovations in the late 1830s or early 1840s, which probably account for the Greek Revival period trim and porch, dormers were added at a later date. The house was constructed of uncoursed fieldstone and surmounted by a steeply pitched gable roof pierced by interior end chimneys. The building's stone construction and long, low form with steep gables are typical of Dutch, German, and English settlement groups in the late 18th century; however, its specific framing method and spatial divisions are indicative of English building practices and may reflect the family's Long Island origins. These differences are particularly evident in the interior of the older section, which features a jambed fireplace, more and smaller
