This triple-A-roofed, I-house is three bays wide and single-pile with a wide gabled rear wing. The house has plain weatherboards, vinyl windows, and diamond vents in the gables. The two-light-over-three-panel door is sheltered by a full-width, shed-roofed porch supported by replacement turned posts. A hip-roofed extension of the porch wraps around the left (west) elevation as a carport supported by turned posts on a brick knee wall. There is an exterior end brick chimney in the left (west) gable, low decorative gables on the side elevations of the rear wing, and a projecting bay window on the right (east) elevation of the rear wing. A sign in front of the house reads “Sparrow House c. 1850” and county tax records date the building to 1921. However, the architecture is consistent with that of turn-of-the-twentieth-century house.
Likely older than "turn of the twentieth century" given the exterior/gable end chimney on the west side of the house. I don't know the research to establish an 1850 date, but the decorative front gable may have been a later addition, along with the front porch; to hazard a guess, as the nominator did, I'd certainly say it was built before ~~1885.
