The result of a competition held in 2002, the winning design from Rem Koolhaas's office was envisioned as the "reinvention of the skyscraper as a loop."
"CCTV defies the skyscraper's typical quest for ultimate height. Rising from a common platform, two towers lean towards each other and eventually merge in a perpendicular, 75-metre cantilever...The structure of the CCTV Headquarters, and the forces at work within it, is visible on its façade: a web of diagonals that becomes dense in areas of greater stress, looser and more open in areas requiring less support. The façade itself becomes a visual manifestation of the building's structure."
