Marina City - Architecture

Architecture

The two towers contain identical floor plans. The bottom 19 floors form an exposed spiral parking ramp operated by 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 beside 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 meter) 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 roofdecks.

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

The corn-cob appearance of the towers is said to have inspired a similar design for the Corinthian Tower in New York.

In 2007, the condominium board controversially claimed to own common law copyright and trademark rights to the name and image of the buildings, although they do not own the parking garage portion of the buildings located below the 20th floor. They claim that any commercial use (such as in movies or Web sites) of pictures of the buildings or of the name "Marina City" without permission is a violation of their intellectual property rights.

Famous quotes containing the word architecture:

    No architecture is so haughty as that which is simple.
    John Ruskin (1819–1900)

    They can do without architecture who have no olives nor wines in the cellar.
    Henry David Thoreau (1817–1862)

    And when his hours are numbered, and the world
    Is all his own, retiring, as he were not,
    Leaves, when the sun appears, astonished Art
    To mimic in slow structures, stone by stone,
    Built in an age, the mad wind’s night-work,
    The frolic architecture of the snow.
    Ralph Waldo Emerson (1803–1882)
