Marina City is a mixed-use residential-commercial building complex in Chicago, Illinois, United States, North America, designed by architect Bertrand Goldberg. The multi-building complex on State Street on the north bank of the Chicago River on the Near North Side, directly across from the Loop, opened between 1963 and 1967. Portions of the complex were designated a Chicago Landmark in 2016. The towers’ symbolic similarity to rural Illinois corncobs has often been noted in media.
The complex consists of two 587-foot (179 m), 65-story apartment towers, opened in 1963, which include physical plant penthouses. It also includes a 10-story office building (now a hotel) opened in 1964, and a saddle-shaped auditorium building originally used as a cinema. The four buildings, access driveways, and a small plaza that originally included an ice rink are built 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.
The two towers contain identical floor plans. The bottom 19 floors form an exposed spiral parking ramp operated by valet with approximately 896 parking spaces. The 20th floor of each contains a laundry room and gym 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 beside the House of Blues. Originally rental apartments, the complex converted to condominiums in 1977, but still contains a number of rental units.
Marina City apartments are unusual in containing almost no interior right angles. On each residential floor, a circular hallway surrounds the elevator core, which is 32 feet (9.8 m) in diameter, with 16 sector-shaped units arrayed around the hallway. Apartments are composed of these units. Bathrooms and kitchens are located towards the inside of the building. Living areas occupy the outermost areas of each unit. Each unit terminates in a 175-square-foot (16.3 m²) 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 might 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 33 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.
