This brick building in the Mediterranean Revival style is the most architecturally pleasing along the street. Alternating red and black bricks in a Flemish bond add color to the flat wall surface, continued in the color and texture of the tiled hipped roof. Although DeLongchamps preferred the Classical Revival style for public buildings, he designed several modest Mediterranean Revival structures for small towns in Nevada during the 1930s. The architect's love of order is apparent in the museum's symmetrical facade with a gabled central bay. The building functioned originally as the first Sparks branch of the Washoe County Public Library, occupying the second floor; the City of Sparks Justice Court occupied the first floor. The building became a museum in the 1990s.
