Ten Eyck Brown for Albert E. Thornton.","why_significant":"The nomination argues it is a fine example of the \"Ultra Modern\" style, a variation of Art Deco, built in Atlanta at the start of the Depression. It introduced movable interior partition walls, circulating ice water on each floor and high-speed gearless elevators. It is also a work of architect A. Ten Eyck Brown and one of the last Atlanta commercial buildings erected before the Depression and World War II halted construction.","narrative":"Rising six stories one block from Atlanta's Five Points, this office building at 10 Pryor Street was constructed in 1930-32 for Albert E. Thornton on land his family had owned for generations. Architect A. Ten Eyck Brown designed it in the \"Ultra Modern\" style, a variation of Art Deco, using tan limestone blocks, black and green marble at the storefront bases and entrance, and bronze door and window frames. Inside, the lobby keeps its decorative plaster ceiling, marble floor, original light fixtures and ornate elevator doors. The building was notable for its time: partition walls could be moved to suit tenants, ice water circulated on each floor, and high-speed gearless elevators served the upper levels. It was among the last commercial buildings completed in Atlanta before the Depression and war stopped such construction. Its architecture and its role in the city's commercial history are the reasons it was recognized.","period_of_significance":"1930-32","architect_builder":"A.
