The Sloan–Parker House consists of the original stone section, which faces toward the Northwestern Turnpike, and a wooden frame addition (built c.1900) adjacent to the original stone section. The stone section's exterior wall is about thick at the basement level and tapers to a thickness of about at the attic level. Most of the stone section's flooring, and the hardware on the doors, are original. Other features of the Sloan–Parker House property include a large barn (built in 1803) and, to the northeast of the house, the Sloan–Ludwick Cemetery.
