1663 Stone House
In January 1662, Pieter Bronck entered into a contract to purchase from the Katskill Indians a tract of land known by the Indian name "Koixhackung". Choosing a site at the base of the Kalkberg Ridge, Pieter built his dwelling, a small single room structure with cellar and storage garret. The original massive beams, wide floor boards, cellar hatchway, and early Dutch door still dominate the interior. This house is the oldest surviving dwelling in Upstate New York.
1685 Stone Addition
The first expansion of the original structure to accommodate the growing family. This "west wing" consists of a hallway, main room, and loft. The great storm of 1792 caused extensive structural damage, requiring rebuilding . It was during this rebuilding that the distinctive paneling was installed.
1738 Brick House
An excellent example of rural Hudson Valley Dutch architecture modified by a federal period taste. This four room dwelling has a large attic and cellar. The structure's size attests to the growing affluence of the Bronck family. Shortly after completion, the brick dwelling was connected to the stone dwellings with the construction of the "hyphen hallway".
