Helmut Jahn’s Endless Tower project was inspired by Constantin Brancusi’s Endless Column, a slender sculpture of repeating prism shapes developed in 1918. Jahn’s translation of sculpture to skyscraper resulted in a remarkable double-layered structure with a faceted tower embedded within a simple, clear glass column. The resulting voids at the building’s corners were intended to function as “skygardens,” large atria providing meeting areas as well as passive climate control for the office space. In 2007 Murphy/Jahn adapted this ambitious design for a single-skin tower planned for Bucharest, Romania, with triangular facets that recall Brancusi’s Romanian Endless Column monument, erected in 1938.
