Marina City Commentary

'"Marina City, in 1959, is a thirty-six-million- dollar project built on only three acres of land in the heart of Chicago's Loop. A dramatic landmark in the Chicago skyline, it culminated thirty years of thought and development for Goldberg. Each of the twin, sixty-story towers had four hundred and fifty apartments in its upper two-thirds, with the lower third a continuous parking ramp that spirals upwards, accommodating four hundred and fifty automobiles. Since the residential level starts at the twenty-first story, magnificent views of the city are enjoyed from every apartment.
"For many years Goldberg had felt there were advantages in the use of circular forms: the aerodynamic properties in a cylindrical high-rise structure; the structural equidistance from the center, and therefore uniform function of all parts; the absence of special corner conditions; and the creation of centrifugal or 'kinetic' spaces resulting from non-parallel walls. The towers derive much of their rigidity from the 35-foot-diameter cylindrical core that houses each building's services and utilities like a vertical street. Service spaces in apartments were grouped toward this core, giving living areas the light and view. The construction of the core preceded that of the floors, providing a rising foundation for the erection crane, thereby saving many working days. The project is all-electric, with heat and hot water individually produced in each apartment.'
