It is also significant in Architecture as one of the finest and most intact Chicago-style commercial buildings in Texas, and as an early example of reinforced concrete flat-slab construction.","narrative":"Standing at the corner of Market and South St. Mary's Streets beside the San Antonio River Walk, this seven-story warehouse was completed in 1919 for the San Antonio Drug Company. Designed by Adams and Adams with engineering by the W.E. Simpson Company, it is built of reinforced concrete flat slabs on octagonal columns, with a red brick veneer, terra cotta trim and steel sash windows in the Chicago style. The company, the city's oldest wholesale drug business, occupied the building until its 1963 merger with Southwestern Drug Corporation, which kept operating there until 1984. At that time it was called the largest independent wholesale drug house in the Southwest. The building is valued as a leading Chicago-style commercial design in Texas and as an early local example of flat-slab construction. It has been vacant since 1984 but remains highly intact, and plans call for conversion into a hotel.","period_of_significance":"1919-1943","architect_builder":"Adams and Adams Architects; W.E.Simpson Company (engineers)","architectural_style":"Late 19th and Early 20th Century American Movements: Chicago","criteria":["A","C"],"status_note":"Vacant since 1984; the owners plan to develop it as a 140-unit all-suite hotel.
