The Charles S. Simpson House is a historic building located on the east side of Davenport, Iowa, United States.

He maintained his position as the bank president in Le Claire after the move, but also served as treasurer of the Midland Supply Company, a vending machine and cigar lighter dealership.

[3] The Simpson house is a fine Davenport example of the renewed interest that the United States had in Colonial Revival architecture around the turn of the 20th-century.

The two-story brick house features a high hipped roof with curved dormers, a six-bay front, a porte-cochere, and a full height entrance.

The single-door entrance is framed by columns in the Doric order, a semicircular pediment, and sidelights.
