The CCTV Headquarters is a 51-floor skyscraper formed out of a pair of conjoined towers that sits on the East Third Ring Road, Guanghua Road in the Beijing Central Business District (CBD) and serves as the headquarters for China Central Television (CCTV). Rem Koolhaas and Ole Scheeren of OMA were the architects in charge for the building, while Cecil Balmond at Arup provided the complex engineering design. The building is among the world's largest office buildings.

The building's construction began on 1 June 2004 and its façade was completed in January 2008. The structure was feted by some architectural critics as "the greatest work of architecture built in this century" and was named the 2013 Best Tall Building Worldwide by the Council on Tall Buildings and Urban Habitat.

Architecture critics claim that "Mr. Koolhaas, of the Office for Metropolitan Architecture, 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," thus giving rise to "the slippery symbolism of its exterior." The main building is not a traditional tower, but a loop of six horizontal and vertical sections covering 473,000 m (5,090,000 sq ft) of floor space, creating an irregular grid on the building's façade with an open center. The construction of the building is considered to be a structural challenge, especially because it is in a seismic zone. Rem Koolhaas has said the building "could never have been conceived by the Chinese and could never have been built by Europeans. It is a hybrid by definition". Because of its radical shape, it is said that a taxi driver first came up with its nickname dà kùchǎ (大裤衩), roughly translated as "big boxer shorts". Locals often refer to it as "big pants".

The building was built in three buildings that were joined to become one and a half buildings on 30 May 2007. In order not to lock in structural differentials, this connection was scheduled in the early morning when the steel in the two towers cooled to the same temperature. The CCTV building was part of a media park intended to form a landscape of public entertainment, outdoor filming areas, and production studios as an extension of the central green axis of the CBD.

The Office for Metropolitan Architecture won the contract from the Beijing International Tendering Co. to construct the CCTV Headquarters and the Television Cultural Center by its side on 1 January 2002, after winning an international design competition. The jury included architect Arata Isozaki and critic Charles Jencks. It is among the first of 300 new towers in the new Beijing CBD. Administration, news, broadcasting, and program production offices and studios are all contained inside.

CCTV Headquarters was officially opened by the chairman on 1 January 2008. Among the distinguished guests at the opening were Hu Jintao, Jiang Zemin, Wen Jiabao and Guo Jinlong.

CCTV Headquarters went on to be feted by architecture critics as perhaps "the greatest work of architecture built in this century", and was awarded the 2013 Best Tall Building Worldwide from the Council on Tall Buildings and Urban Habitat.

An adjacent building in the complex, the Television Cultural Center, caught on fire, ignited by fireworks on Lantern Festival day, 9 February 2009, before the building's scheduled completion in May 2009. It was to have the Beijing Mandarin Oriental Hotel, a visitor's center, a large public theater, two recording studios with three audio control rooms, a digital cinema and two screening rooms. The 160-metre-tall (520 ft) Mandarin Oriental Hotel was badly damaged and one fire fighter was killed. The director of the project and 19 others were imprisoned. On 25 October 2009, scaffolds were set up in the front gate of CCTV which indicated the renovation of the building had begun. As of 9 February 2010, the main CCTV tower was still unoccupied.
