eventually got painted white and then a bridge was added that connected the second story of the building to the elevated railroad. In 1898, Schlesinger and Mayer decided to remove the original building located on State and Madison replace it with a new building designed by Sullivan. Sullivan had both a nine and twelve-story proposal made up for this new building. They eventually started with a nine-story portion of the building that was made on the Madison Street side next to the original portion of the Adler and Sullivan renovations. In 1902, Schlesinger and Mayer came back to Sullivan wanting a twenty-story building on State and Madison, eventually settling for the final twelve stories. The Madison Street portion that was added earlier did not structurally support twelve stories so was left as is. Sullivan came up with a three-stage plan to finish the new building and allow Schlesinger and Mayer to keep their business running during the Christmas season. The building is remarkable for its steel-framed structure, which allowed a dramatic increase in window area created by bay-wide windows, which in turn allowed for the greatest amount of daylight into the building interiors. This steel framed structure uses the post-and-lintel technique to provide a strong, light, and fireproof steel skeleton. The exterior of the building consists of a grid of piers and spandrels that reveals the post-and-lintel technique that supports the building. The design was the first use of what became known as the Chicago window. At street level, the broad expanses of glass allowed for larger displays of merchandise to outside pedestrian traffic creating the idea of the sidewalk showcase. In between the windows were bands of terra cotta, replacing an earlier plan for white Georgia marble, to save cost and weight and to avoid delays arising from a stonecutter's strike. The design featured bronze-plated cast-iron ornamental work above the rounded tower. The project also included a fire suppression sprinkler system, supplied from a water tower on the roof. Sullivan designed the corner entry to be seen from both State and Madison. The attractive ornamentation above the entrance would give the store an elegant and unique persona important to the building's competition with neighboring stores. The building is one of the classic structures of the Chicago school. The way this technique was used on the lower floors of the building was so elaborate that it used the natural lighting
