"Constructed in approximately 1885, the Oldham House is located at 321 South Denver Street in El Dorado. The home sits on a large lot and is surrounded by homes constructed during the housing boom of the 1920s. The Oldham House is a compound square plan with projections ranging from small bays to roomsized bays and a round tower. Typical of Queen Anne houses constructed in the late-nineteenth century, the house features a steep hipped roof with lower cross gables and two prominent limestone chimneys. The principal building material is quarry-faced limestone, laid in regular courses. The Oldham House is nominated to the National Register as an unusual vernacular example of Queen Anne style architecture."
