High above Beijing, two leaning towers waited to be joined. Between them, a 75-meter cantilever would complete a continuous loop, with little room for error. A miscalculation could make the frame twist, buckle, or collapse. The defining moment of CCTV Headquarters architecture came when an improbable shape had to become a stable building.
The connection captured the tension behind the project. A headquarters designed to express confidence and control became one of Beijing's strangest landmarks: structurally daring, politically loaded, publicly mocked, and impossible to overlook.
Why CCTV Headquarters architecture rejected the vertical default
By the late 1990s, CCTV had outgrown its headquarters. But the 2002 commission was about more than office space. China's central television was the government's official mouthpiece, responsible for shaping public opinion across China. Its new home had to be visible, modern, and large enough for the ambitions surrounding the 2008 Olympics.
Rem Koolhaas and the Office for Metropolitan Architecture rejected what he called the vertical default. Rather than design another isolated glass tower, OMA proposed six main parts forming a three-dimensional loop: two leaning towers, each about 234 meters, joined by a massive two-section cantilever above and a two-section horizontal podium below. It was a skyscraper refusing to behave like one.

The geometry had a practical purpose. Offices, broadcasting studios, editing rooms, technical areas, and production spaces were connected as a machine for making media. The loop made those workflows visible in the building's form. A tightly controlled state had invited an international firm to express connection, movement, and controlled chaos while still projecting order.
The 75-meter cantilever made the loop a structural gamble
OMA worked with ARUP and structural designer Cecil Balmond to make the proposal stand. Traditional vertical columns could not manage the forces where the leaning towers met the overhanging top. ARUP designed a diagrid system, a dense web of steel triangles across the facade that distributed weight diagonally around the loop.
Built last, the cantilever joined the towers like a horizontal bridge in the air. As the connection formed, parts of the frame stretched, bent, and twisted; some worked in tension, others in compression. Every joint and weld had to withstand unusual forces. The facade's pattern is not decoration. It reveals where the building works hardest.

Construction began in 2004 and proceeded cautiously. The headquarters was not ready for the 2008 Olympics, the event it had been intended to meet. It opened in 2012 after nearly a decade of construction. National ambition set the deadline, but structural ambition made it unrealistic.
Big Pants, state power, and a landmark that missed its moment
The Chinese government wanted a commanding national symbol. Beijing offered a less solemn name: Dakucha, or Big Pants. The nickname can sound affectionate, mocking, or faintly embarrassed. It also punctures the official image efficiently. Monumental architecture may seek to control its meaning, but the public gets naming rights.

In 2009, illegally launched Lunar New Year fireworks ignited insulation on the adjacent TVCC complex. One firefighter was killed and dozens more were injured. The main headquarters was not damaged, but images of the burning tower spread before censors could stop them. The disaster became attached to a project already facing questions about a Dutch architect designing the home of China's state media: bold openness, or imported spectacle?
The completed building supports over 10,000 employees across nearly 400,000 square meters, more than 4 million square feet. Its organization supports CCTV's media workflows, but the diagonal grid limits interior flexibility, and maintaining the cantilevered sections is expensive. Around $900 million US dollars bought a functioning media hub, a costly state symbol, and a challenge to the glass box associated with Mies van der Rohe. More than a decade later, nothing else quite like it has been built. That may signal admiration, warning, or both.
