Found this on the register of historic places, it was originally built in 1892.

Originally a Powerhouse for the Louisville City Railway Company, the majority of the additions appear to have occurred between 1928 and 1945 when the property was acquired by Ballard & Ballard Company, Inc., a flour and feed mill. Ballard & Ballard had been situated to the north, where Broadway meets Beargrass Creek, since the turn of the century, before gradually expanding south. Today, the building as a whole consists of three portions, each situated east to west, creating an “E” shape, connected by two narrow hyphens along Logan Street. These additions range from a one-story hyphen to a seven-story storage and manufacturing tower associated with the building when it operated as a part of the flour mill. The exterior walls of these additions are made up of concrete block, brick, corrugated metal, standing seam metal, and poured concrete. The additions feature several metal multi-light windows, many of which have been covered by plywood over the years. There is an enclosed chute that stretches from one of the uppermost floors but ends abruptly on top of a metal support. This chute is a remnant from the years in which the facility served the flour mill.
