The Arndt House is a post-and-beam dwelling with exposed structural elements at both the interior and exterior and an open floor plan in the public living areas. The house is built into a sloping parcel, allowing for a two-story rear elevation that comes as a surprise after encountering the modest single-story gabled facade. Deeply recessed porches are at both elevations. The house was listed in the National Register of Historic Places in 2011; it is also a Raleigh Local Historic Landmark.
