The columns, main cornice, frieze, and the doors and door trim were constructed of metal, with other trim features of concrete. This building is missing and presumed demolished.

The William Moss House is a two-story duplex located at 528 West Genesee Street. This house was built in approximately 1908, and is unusual in Iron County as a middle-class duplex, more so because the floor plans of the first and second floor are dissimilar. It is likely that the original owner, William Moss, occupied the first floor and let out the second. The house is a two-story structure with hipped roof, bracketed eaves, and narrow clapboard siding. It has an Ionic front porch and geometric pattern window sash. The Munro – M.A. Hanna Mining Company Office Building is an office building located at 107 North Fourth Street.
