With a construction history dating to 1663, it is believed to be the oldest surviving building in Upstate New York,[3] and is a well-preserved example of early Dutch and Swedish Colonial architecture.

The house consists of a series of connected structures, oriented roughly north–south on the south side of Pieter Bronck Road east of Coxsackie Creek.

The southernmost section is the oldest part: it is a single-pile structure with thick stone walls, with a steeply pitched gable roof.

Its interior as built consisted of single open chambers on two floors, with a loft space in the attic.

In 1792 the Broncks added a stone addition to the rear of the 1738 structure, using construction methods similar to that of the 1663 building.
