John Hancock Center is located on Chicago's "Magnificent Mile," an elegant length of Michigan Avenue which has long been famous for its smart shops, galleries, restaurants and the historic old Water Tower which survived the great Chicago fire of 1871.

The building's lower floors contain 812,000 square feet of office space. Over seven hundred apartments ranging in size from studios to four-bedrooms are located on its upper stories. Office and residential tenants are served by separate entrances and elevators, so both groups enjoy complete privacy and security. The entrance for apartment residences is on Delaware Place. Office and commercial entrances are on Michigan Avenue, Delaware Place and Chestnut Street.

Apartment dwellers step into street-level elevators and travel non-stop to the 44th floor "Sky Lobby." The Sky Lobby's amenities include a restaurant, commissary, health club, service shops and the highest above-ground swimming pool in the world (546 feet). From 44, another bank of elevators carries residents to apartments whose features include glassed-in "sky terraces" for year-around lounging in sky-high surroundings.

A resident gazing out of his living-room window on the 92nd floor (the topmost apartment level) in the John Hancock Center stands precisely 1,003 feet, 6 inches above ground. Our resident enjoys a view unequalled in any other dwelling place on earth. The same individual, if he or she works in the building, can "commute" to the office in 90 seconds.

Other features, from the concourse level through the 12th floor, include Bonwit Teller, a store in keeping with the "Magnificent Mile" tradition; a broad variety of service and retail shops; Upper Avenue National Bank; and heated indoor parking for 1,400 cars which enter and leave floors 6 through 12 via a spiral ramp.

More than 50 percent of the 104,000-square-foot site on whicch the building is located I devoted to open space. The landscaped plaza area features a skating rink in winter which serves as a reflecting pool in summer.

John Hancock Center's unique design reflects the logic of form following function. Consider the building's tapering sides, for example. Office space is most efficient and produces optimum flexibility when it is offered in large blocks. This space is thus located on the lower and larger floors of the building. Apartment dwellers wish to enjoy an exciting, high-level view of the city. In John Hancock Center, apartments begin where many building's end-at the 45th floor-and continue through the 92nd story
