Built in 1910, the Richardson-Seehorn House is the finest example of the American Foursquare style, an early subtype of the Prairie style, in Spokane’s south side Hill Addition. The house stands on one of the first lots purchased following the promotion of the addition by the Arthur D. Jones Company in 1906. In addition to its architectural significance, then, the house is also historically significant for its association with the development and subsequent settlement of Spokane’s lower South Hill.
