Marshall Building & Gallery 218

Historic Third Ward building with six floors of renovated spaces.
Built in 1906-07 by architects George Ferry and Alfred Clas, the Marshall Building was originally named John Hoffman & Sons Grocery Building after the owners and primary tenant. The building was originally built as a five story building, however, in 1911 the building completed a second topping-off ceremony with the addition of a sixth floor in order to accommodate the growing retail operations of John Hoffmann & Sons wholesale grocery firm. Hoffman’s coffee roasters were located on the sixth floor and a sugar pulverizer was on the fourth floor.
Beginning in the late 1920s, Hoffman & Sons shared space with various manufacturers. The box-like shape and arched pavilions were common features of the many warehouses at that time, yet the way it was constructed was groundbreaking with the assistance of prized structural engineer Claude A.P. Turner. Turner, a pioneer of reinforced concrete construction, made the building a test project for his pioneering construction method known as the Turner System or the Spiral Mushroom System. Most buildings around this time used wood-and-steel-framed floors, which made construction more expensive and tedious, but Turner’s system used flat-slab concrete floors that were supported by mushroom-headed columns and reinforced with steel rebar. The cost-effective technology resulted in a sturdy, built-to-last building. The Marshall Building’s structure is the oldest extant example of the “mushroom” flat-slab system developed by reinforced concrete. The technique transformed the design and construction of reinforced concrete floors worldwide. In 1942, Roundy’s purchased John Hoffmann & Sons and the building, which was then used for coffee roasting and sugar pulverizing. In 1947, residential real estate broker George Bockl purchased the building and in 1948 renamed it the Marshall Building after his son, Robert Marshall. Tenants run the gamut to include art galleries, artist studios, attorneys, photographers, software companies, advertising agencies, printers, nonprofits, a local newspaper, a restaurant, a bakery and a men’s clothing store.
