While the Chicago School might be known for sparse ornamentation, the Wainwright Building proves that wrong; from the door on the first floor to the smallest detail, the building is accented with perfect, innovative designs.
There is the most interesting design element on the vertical elements in between the windows on the floor right above the base floors.
I came to the wonderful discover that the terracotta spandrels between the windows on each floor are different, with uniformity around each floor. The next eight photos are each floor, from bottom to top.
And finally, the pediment of the Wainwright Building continues it elaborate, innovative decoration pioneered by Sullivan, though with a little classical influence encroaching with the Composite capitals.
