That didn’t stop him from capitalizing on his reputation and designing some of the most flamboyantly distinctive edifices of this era, including the Beijing headquarters of the CCTV broadcasting company, with its two tilted towers joined at the top and bottom to frame a dramatic void. Aside from the new World Trade Center, it’s hard to think of a more contentious architectural project in the last few years than The CCTV Building, the headquarters of China Cable - the building has often been fondly termed as the ‘Beijing robot’ . Some once said it was physically impossible, others were discouraged by the fire that delayed its completion, and others still said it looked like a pair of pants, but the CCTV headquarters building in Beijing ,may yet be the greatest work of architecture built in this century. The structure was initially built as two separate towers which finally converged at the top in 2007, joined by a 75-meter cantilever. The connecting section is a marvel of modern architecture, appearing precarious despite being fully structurally sound. Mr. Koolhaas, has always been interested in making buildings that expose the conflicting energies at work in society, and the CCTV building is the ultimate expression of that aim, beginning with the slippery symbolism of its exterior. The building has been a highly visible part of the cityscape in this nation’s capital since late in the last decade, rising across an elevated freeway from the generic towers of Beijing’s new business district. It speaks of the growing face of china’s power- Its two 50-story legs, which house offices and production studios, are joined at the top by a 13-story bridge whose angled form juts out precariously over a plaza. Everything is magnanimous about the building, and there are no qualms about it.
