Many comfortable foursquare, homestead temple-form, and bungalow houses were built in Iron River in the early twentieth century during Iron County's period of greatest economic activity. Distinguished among others on 7th and 8th avenues in the southwest quarter of Young's Addition to the city are the Harvey Van Wagner House (c. 1920) at 103 N. 7th Avenue, and the Joseph Joseph House (1925) at 105 N. 8th Avenue. Craftsman ornamentation is applied to the little stucco Wall-Seppanen bungalow (c. 1915) at 21 N. 7th Avenue. The interpenetration of inner and outer space achieved by the roof that sweeps over the veranda, the dormer window, and the hoodlike roof over the side bay mark this house as a variation of the bungalow form. Exposed rafter ends, the triangular braced supports under the eaves, and the cobblestone exterior chimney express the materials and construction in a way characteristic of the Craftsman style. The house was built for James S. Wall (b. 1852) and his wife, Britania Nichols. Wall was manager of the Oliver Iron Mining Company and president of the Miners' State Bank. Later, in 1943, the family of Wayne E. Seppanen, a mining engineer and superintendent of the Caspian Mine, occupied the house.
