CCTV HQ, Beijing, China

The CCTV Headquarters is a skyscraper in the Beijing Central Business District. The building is the headquarters of China Central Television. Groundbreaking took place on September 22, 2004 and the building was completed in December 2008.

The main building is not a traditional tower, but a continuous loop of six horizontal and vertical sections covering 4.1E+6 square feet (381,000 m2) of floor space, creating an irregular grid on the building’s facade with an open center. The construction of the building is considered to be a structural challenge, especially because it is in a seismic zone.

The building was built in two sections that were joined to complete the loop on December 26, 2007. In order not to lock in structural differentials this connection was planned to be completed at the coldest time of night when the steel in the two towers cooled to the same temperature.

Architect : Rem Koolhaas
