Building History

The 1635 building was constructed in 1924 by the Standard Sanitary Manufacturing Company. Located in the Menomonee Valley, this building was a smaller version of the company’s headquarter building located in Pittsburgh, Pennsylvania. The company manufactured plumbing, heating, and cooling parts and over time merged with other companies. The building was eventually sold to Geuder, Paeschke & Frey, a tinware manufacturer, who operated several buildings in the Menomonee Valley. In recent years, the building was used for storage. It was purchased in 2015 by John Shannon to be the site of GUARDIAN Fine Art Services.
