Today OMA participated in the official construction completion ceremony for the China Central Television (CCTV) Headquarters in Beijing, which will start to be used later this year. Designed by OMA as a reinvention of the skyscraper as a loop, construction on the building began in 2004. At approximately 473, 000m², CCTV - accommodating TV studios, offices, broadcasting and production facilities - is OMA's largest ever project and its first major building in China.
