Marina City is a mixed-use residential/commercial building complex that occupies an entire city block on State Street in Chicago, Illinois. It sits on the north bank of the Chicago River in downtown Chicago, directly across from the Loop district. The complex consists of two corncob-shaped, 587-foot (179 m), 65-story towers, which include five-story elevators and physical plant penthouses. It also includes a saddle-shaped auditorium building, and a mid-rise hotel building, all contained on a raised platform next to the Chicago River. Beneath the platform, at river level, is a small marina for pleasure craft, giving the structures their name. Designed by Bertrand Goldberg, Marina City was the first building in the United States to be constructed with tower cranes.

The Marina City complex was designed in 1959 and completed in 1964 at a cost of $36 million, financed to a large extent by the union of building janitors and elevator operators, who sought to reverse the pattern of white flight from the city’s downtown area. When finished, the two towers were both the tallest residential buildings and the tallest reinforced concrete structures in the world. The complex was built as a city within a city, featuring numerous on-site facilities including a theatre, gym, swimming pool, ice rink, bowling alley, several stores and restaurants, and, of course, a marina.

Marina City was built in a joint venture with Brighton Construction Company, owner: Thomas J. Bowler, and James McHugh Construction Company. James McHugh Construction Co. subsequently built Water Tower Place in 1976 and Trump Tower in 2009, both also tallest reinforced concrete structures in the world at the time.

Marina City was the first urban post-war high-rise residential complex in the United States and is widely credited with beginning the residential renaissance of American inner cities. Its model of mixed residential and office uses and high-rise towers with a base of parking has become a primary model for urban development in the United States and throughout the world and has been widely copied throughout many cities internationally. Marina City construction employed the first tower crane used in the United States.

The two towers contain identical floor plans. The bottom 19 floors form an exposed spiral parking ramp operated by the valet with 896 parking spaces per building. The 20th floor of each contains a laundry room with panoramic views of the Loop, while floors 21 through 60 contain apartments (450 per tower). A 360-degree open-air roof deck lies on the 61st and top story. The buildings are accessed from separate lobbies that share a common below-grade mezzanine level as well as ground-level plaza entrances besides the House of Blues. Originally rental apartments, the complex converted to condominiums in 1977.

Marina City apartments are unique in containing almost no interior right angles. On each residential floor, a circular hallway surrounds the elevator core, which is 32 feet (10 m) in diameter, with 16 pie-shaped wedges arrayed around the hallway. Apartments are composed of these triangular wedges. Bathrooms and kitchens are located nearer to the point of each wedge, towards the inside of the building. Living areas occupy the outermost areas of each wedge. Each wedge terminates in a 175-square-foot (16.3 square meters) semi-circular balcony, separated from living areas by a floor-to-ceiling window wall. Because of this arrangement, every single living room and bedroom in Marina City has a balcony.

The apartments are also unusual in that they function solely on electricity; neither natural gas nor propane serves any function. The apartments are not provided with hot water, air conditioning, or heat from a central source, as was the common practice at the time the towers were built. Instead, each unit contains individual water heaters, heating and cooling units, and electric stoves; residents pay individually for the electricity needed to run these appliances. This may have been a financial decision on the part of the building owners; at the time these towers were constructed, local electric utility Commonwealth Edison provided expensive building transformers at little or no charge provided the buildings were made all-electric.

In addition, the residential towers are noted for the high speed of their elevators. It takes approximately 35 seconds to travel from the lower-level lobby to the 61st-floor roof decks.

The towers were awarded a prize by the New York Chapter of the American Institute of Architects in 1965 for their innovation.
