Noted architect Daniel Burnham, FAIA, designed this Chicago School skyscraper between 1907 and 1909. Burnham was an American architect and urban designer, known among other things as Director of Works for the famous World’s Columbian Exposition in Chicago and the design of the famous Flatiron Building in NYC. It was the first building in Iowa to use a steel skeleton and brick veneer. Originally conceived as a Commercial Style building incorporating elements of Beaux-Arts style in its propostions and detailing, in the 1930’s the facade was renovated in Art Deco style. Evidence of the original design can be seen in the south alley. It was listed on the National Register of Historic Places in 2002. 2014 brought another renovation by Slingshot Architecture and Nelson Construction & Development. Four of its 11 floors retained an enormous amount of the building’s original fabric, including its corridors with marble veneers, wainscoting, and doors with transoms. In the rehabilitation, doors were sized to match the original size of the openings and the original grid of the building design was used by the architects, even if nothing remained that was original.
