The building is on the southwest corner of the Carrollton Public Square. Built in 1837, it is a perfect example of the popular Federal architecture. Its central door is framed by white side windows and a fan window above. A light sandstone arch surmounts the frame. The hipped roof is framed on both sides by two large chimneys.
The building became a National Historic Place in 1970, and is now a historic house museum operated by the Carroll County Historical Society. The house is owned by the Ohio History Connection. There are several period rooms and exhibits about the McCook family and the Civil War.
