It notes the residence was built in 1832 by Andrew Layman as a tavern and residence, and that the property was sold out of the family in 1937.","narrative":"Built in 1832 by Andrew Layman, a cordwainer, the Isaac Kulp Farm in Upper Gwynedd Township, Montgomery County, combines a three-story stone residence with a stucco exterior, a stone Pennsylvania bank barn, and a root cellar. Layman intended the house as both a tavern and his home, but he never opened the tavern and lost the property to creditors within a few years. Isaac Kolb, a Mennonite farmer, bought the property in 1847 and the Kolb and Kulp family farmed it for roughly ninety years. Census records from 1850 to 1880 show the farm, though smaller than its neighbors, often matched them in the quantity and value of its products, including butter, hay, and dairy cattle. The residence is regarded as an excellent example of the Georgian double-pile plan, with a symmetrical five-bay facade and interior end chimneys. The barn, which has an overhanging forebay and banked entrance, is an example of its type. The property is listed for its agricultural and architectural significance.","period_of_significance":"1832-1937","architect_builder":null,"architectural_style":"Colonial/Georgian","criteria":["A","C"],"status_note":"Contributing residence, barn and root cellar; a circa 1960 concrete block office building does not contribute.
