Enter through the original white marble vestibule, and the first floor is dedicated to entertaining (which the couple does a lot of) with an open sitting room, large formal dining room and prep kitchen. Take the stairs or elevator to the second floor, which functions as the couple’s primary living quarters, and you’ll find a modern chef’s kitchen — a necessity for Ballis, who writes foodie fiction. The third floor, which suffered a fire in the 1980s and thus lacks many of the mansion’s original elements, is the ultimate couple’s suite. It boasts his and hers dressing rooms, a spacious master bedroom and master bathroom with bathtub views of Willis Tower.
