Sometimes referred to as the “Grange Road” project.
“Conceived as a set of prefabricated units hoisted onto a structural frame, the Colonnade apartment tower is another attempt by Rudolph to design with prefab units, what he called the ‘twentieth-century brick.’ The original concept for this kind of structure dates back to the 1960s and particularly to his 1967 design for a Graphic Arts Center in lower Manhattan, which established the fundamental principles for his designs of tall buildings in the subsequent three decades.
Although for technical and financial reasons the Colonnade was built of pour-in-place concrete with conventional techniques rather than with prefabricated units, the final product retains much of the visual impact of the original concept.”
