It later housed a grocery store and other businesses and was continuously occupied from the time of its construction until its demolition. In addition, a potential archeological site lies beneath the parking lot at the rear of the building, which was the location of the John Armstrong adobe house. Built in August of 1882, the house was occupied by Armstrong for nearly ten years. The house was razed to the ground level in 1979 and immediately paved over, sealing a site continuously occupied for nearly 100 years. This archeological site was excavated in 1997, just prior to demolition of the Miller Block for construction of a new building on the site.
Brick pilasters leading to a simple continuous denticulated and corbelled cornice define the bays.
Recessed brick panels resting on steel beams fill the space above the original transom line. The building faced east onto Mill Avenue and south onto 5th Street. The corner bay featured a diagonal corner entry with original arched doorway. The original wooden storefronts, three toward Mill Avenue and one toward 5th Street, had been modified, as had the interiors with suspended ceilings. The building was demolished in 1998.
