One of Chicago's best finds, this treasured residence - an entire floor in an intimate boutique building designed by famed architect Benjamin Marshall - exudes opulence and offers practicality. Rich in preserved architectural details, the one-of-a-kind square floor plan elegantly works for both entertaining and day-to-day living. The formal rooms all flow from the main gallery: A glamorous living room framed by a marble fireplace and windows on all sides; a large dining room with extensive molding and decorative windows; and a library/bedroom with an arched entry and built-in shelving. A welcomed surprise for vintage residences, the fabulous chef's kitchen opens to an enormous great room for casual hang-out time. Off the great room is a wonderful private terrace which leads a few steps up to an incredible landscaped common roof garden. The bedrooms and ensuite baths have all been tastefully renovated to modern standards. Prime location right off the lakefront where parks, paths, beaches, tennis courts, and the bird sanctuary await. One garage space+one outdoor parking space included. Truly, a magnificent offering.
