This farmhouse sits atop a terrace at the intersection of Lusk Run and Crystal Beach roads. It is the oldest of four stone houses built by a mason named Adam. At the time of its completion in 1798, the house had a four-over-four plan with a central hall. There was a major fire in 1865, which nearly destroyed the house. Therefore, most of the woodwork, especially on the interior, dates from the subsequent rebuilding. It is probable that the first floor was changed at that time to its present configuration of one room to the north and three rooms to the south. The house features exterior corner quoins and a three-bay front porch with sawn ornament. The sprawling Central Mountain Valley High School (1997–2000 Quad 3; 64 Keystone Central Drive) across the street is the largest indicator of encroaching suburbia.
