Designed by Rem Koolhaas and Ole Scheeren of the Office for Metropolitan Architecture (OMA), the CCTV Headquarters in Beijing rejects the traditional vertical race of the skyscraper. Completed in 2012, the 234-meter structure unifies the entire television production process into a continuous loop of two leaning towers and a dramatic cantilevered bridge. Rather than maximizing height, the design prioritizes connectivity, physical presence, and urban integration, sparking intense debate over state power, structural engineering, and the evolution of global cityscapes.
From structural innovations to severe political and local controversies, the building remains one of the most scrutinized feats of twenty-first-century engineering. This deep dive explores how OMA challenged standard high-rise design, the hurdles faced by engineers at Arup, and how the loop reshaped architectural theory.
The Architectural Vision: Breaking the Skyscraper Loop
For decades, the global corporate skyscraper race focused on height, culminating in slender towers pointing vertically toward the clouds. When China Central Television launched an international competition for its new home in Beijing's Central Business District, OMA bypassed the standard tower approach entirely.
Instead of isolating departments, Koolhaas mapped out the entire workflow of a television network—from administration and news production to recording and broadcasting—and connected them in a continuous circuit.
- The Two Towers: Two leaning towers slant toward each other at a 6-degree angle, defying conventional gravity loads.
- The Overhang: A massive 75-meter cantilever bridges the two towers at a height of several stories, creating a floating loop that alters Beijing's skyline.
- The Facade: A dense web of exterior steel diagrids visualizes the structural stress flowing through the building, acting as both an aesthetic pattern and a primary load-bearing system.
By turning the tower inside out, the design exposes the internal mechanics of state media broadcasting while presenting a shifting silhouette depending on the viewer's angle in the city.
Engineering Challenges and Structural Realities
Building a loop of this magnitude required unprecedented engineering from firms like Arup. Standard skyscrapers transfer loads straight down to a deep foundation. The CCTV Headquarters distributes immense asymmetrical weight across diagonal grids and massive piled raft foundations buried deep beneath Beijing's silty subsoil.
The structural grid is densest where stress concentrations are highest—primarily at the base and along the corners of the overhang—and thins out where loads are lighter. During construction, engineers had to monitor thermal expansion and contraction closely. Because the two leaning towers were built separately before being joined at the top, precision alignment was critical. Crews welded the final connection during the coolest hours of the night to minimize metal shifting caused by daytime heat.
Controversy, Public Reception, and the TVCC Fire
The project didn't emerge without severe friction. Critics and local residents raised concerns about traffic congestion, the immense budget (reported to exceed $900 million), and the assertive aesthetic footprint dominating the Beijing skyline.
Furthermore, the adjacent Television Cultural Center (TVCC), designed as a companion public facility housing a hotel and a grand theater, suffered a devastating fire on Lunar New Year's Eve in 2009 due to unauthorized fireworks display work. This disaster delayed full operations and cast a long shadow over the complex's opening years, prompting strict government reviews on construction safety and public events management across China.
Culturally, the building also drew satirical commentary from locals who noted its unusual geometric profile, highlighting the culture clash between avant-garde Western structuralism and traditional Chinese urban aesthetics.
Cultural Impact on Global Urbanism
Despite initial friction, the CCTV Headquarters altered how architects think about mega-structures. It proved that corporate and state headquarters could express internal corporate logic rather than relying on generic phallic height to assert dominance.
While the building did not kill the traditional skyscraper—as evidenced by the forest of standard towers that quickly crowded around Beijing's Third Ring Road—it expanded the vocabulary of postmodern architecture. It demonstrated that structural engineering could be externalized dramatically, turning gravity and wind loads into visible public art.

Frequently Asked Questions
How tall is the CCTV Headquarters?
The main tower reaches a height of 234 meters (768 feet) across 51 floors. While not the tallest building in Beijing, its massive footprint and unique loop shape give it an imposing visual presence.
Why is the building shaped like a loop?
Rem Koolhaas designed the loop to connect the entire sequence of television production—administration, program generation, broadcasting, and staff housing—into a single continuous workspace rather than separating departments across isolated floors.
Who engineered the structural system?
The structural engineering was led by Arup, which utilized an exterior steel diagrid system to support the leaning towers and the heavy cantilevered bridge.
Can visitors go inside the CCTV Headquarters?
The building is a secure working facility for state media operations and is generally closed to general public tourism, though certain viewing areas and event spaces have hosted public functions.
