The coffee roaster is a good example of an early 20th century Dallas industrial facility and is the last of the company's three roasters to survive. The complex is judged significant locally in industry and commerce.","narrative":"Two linked industrial buildings on North Lamar Street in Dallas housed the Waples-Platter Grocery Co. The grocery house, a two-story brick building of 100 by 200 feet, was built in 1915. Across the street, the four-story brick-faced, steel-frame coffee roaster followed in 1925, built by the Thomas S. Byrne Co. of Fort Worth. Its irregular plan resulted from a land trade that gave the building enough railroad frontage for a second loading door. Inside, steel columns with cast capitals carry heavy machinery, floor heights vary with the equipment, and a skylight lit the roasting ovens on the fourth floor. A steel bridge joined the two buildings. The company began in 1872 as a railroad commissary and grew into a family-run regional food manufacturer and wholesaler, marketing White Swan coffee. The roaster is the last of its three coffee roasters still standing. The complex was listed for its role in local industry and commerce.","period_of_significance":"1915-1925","architect_builder":"Thomas S.
